Where would be the beat place to mount an amp in the trunk?
I'm thinking the back of the seat, but if my subs are pointing at it from pretty close, won't that damage it?
Cashdollar2009

The only reason why your subs should be facing forward is if you plan to seal you enclosure off from the trunk. If not, you are just going to get a lot of cancellation and not a whole lot of sound pressure. (It will not be very loud.) Face your subs to the rear so they can load off of your trunk lid, then your amplifier will be fine on the back of your seat.
Edit: spelling

one of my friends took their car to get a HID installation and they actually have a relay in his wheel well with a plastic bag wrapped over it so it didnt get wet LOL

back of the seat or in the spare tire void cause once you put a sub in better get roadside and take out the spare you got room for a battery and an amp if you wanted

only problem with this area is the amp will get very very hot! had a 500rms boss amp melt from bein in there

get a more efficent amp!! my mrp-m2000 cranked for 30 mins doesnt even reach 40c... and what ohm you running at?
MattismodderX
11-10-2010, 01:55 PM
it melted about 2 years ago. my car is black. when it gets hot in the summer, inner temperatures of my car become oven-like. from it just sitting in the sun, amps cant play for too long loudly (mounted on the back of the backseats) because without even powering them on theyre too hot to touch. so when its one of those days and the amp is in the spare tire well..
scott192
11-10-2010, 02:12 PM
so where in the oven you plan on putting it if its too hot on the back of the seat where the hell you plan on putting it whatever the temp at the back seat is gonna be the temp anywhere else....you plan on putting it under your a/c vent?? like wtf the temp isnt going to change anywhere in the car in the summer if anything the back of the seat would be best cause you can fold down the seat and get some cool air on it from your window!! and in the spare tire holder throw a fan on the top and cut some vents on the other side sure it would work good...and just get a bigger amp so your not workin it so hard! wont get hot

i have an MB Quart 1000.1 discus and a kicker 350.4. its about all my stock alt can handle without crapping out. surprised its lasted this long. if i open my windows with them on the back of the seat it works out ok after about 15 mins. other then that i dont have the room for them without building an amp rack. - which will hopefully be done before spring. picking up either 2 15 XFLs or HDs. then a 2000rms/3000rms amp will be needed depending on the final sub choice
attached is a photo of the current temporary setup. despite its grotesque appearance it sounds very nice. loud as shit. mids are painful. temp sub currently. its only 300rms :lol: had a 2000rms custom built tc sounds 12 in a 3.9 box. sounded sexy but it had a slow painful death

1. Matt was referring to the spare tire well as a bad place because there is absolutely no ventilation in there. On a hot summer day, if the tire well gets warm enough the amplifier has no way whatsoever to vent when it dissipates its heat = amplifier overheating = mechanical failure/ melting or burning up internals/ protection. (With the fan idea, you'd need a fan going either way, you can't just pump "fresh" air in, you need to also remove the heat buildup as well.) Plus with the box more than likely covering the spare tire well, ventilating that area would be rough.
No matter how efficient your amplifier may be, you are still putting your equipment at risk by running it in such conditions... In 99% of cases, the back of your seat is just fine if you drive around with it down. The amplifier heatsinks are developed the way that they are for a reason; to dissipate heat as efficiently as possible for that particular amp. They aren't meant to be mounted at angles/sideways/areas with little to no ventilation.
2. You can't run a dual 2-ohm subwoofer at a 2-ohm final nominal load. Either 1-ohm or 4-ohms for a single subwoofer.
3. There is absolutely no reason to NOT run an amplifier at 1-ohm as long as you can keep your voltage stable and you have the gain matched to the specific driver(s) in your application. If your amplifier can produce the power that you need, USE IT! Efficiency drops when your voltage drops. If you keep your voltage stable then it is up to proper gain settings and proper physical application to ensure that you are running everything safely.
4. Budget: To buy an amplifier that is 1-ohm stable or even .5 stable and you have the electrical to support it, it is definitely cost inefficient trying to find another amplifier to run at 2-ohms to do the same power. For example one amplifier may do 1,000rms @1-ohm, but only 650rms at 2-ohms. In order to find an amplifier that does 1,000rms @ 2-ohms, you are looking at a 1-ohm power rating of about 1,400 to 1,600rms. Wasted power in my opinion, as well as cash. I mean unless you have that money burning a hole in your pocket. (These are just VERY general examples, nothing specific. Just giving an idea.)
Also, roadside assistance? REAL bassheads don't have enough money after buying all of their equipment to afford a tow-truck. lol :p

come on 65 bucks a year come on i spend more on coffee!! its a part of driving your gonna have an issue sometime or another worth it in my books!! and it includes dummy stuff like running outta gas*havnt used*, locking yourself out*gf used 4 times*, towwed my car across the city*used*, and boosting *used on my lastcar* so what would that have been total?? lol
and when you buy an amp buy it to what you plan on using it for daily driver get something nice... i spent 650 on mine and am very happy with it!! more then enough power never gets to hot...and yes i have a black 2 door tinted and it feels like an oven getting in yet i can bump that shit and not worry at all and im running it at 2 ohm with the fi now but was running the HX2's all summer not one issue!! and it was a damn sauna in there

I feel that putting the amp under the car especially if it snows
is bad, because moisture can build up if to cold and short out the amp

I agree, you cant just take any speaker to any amp,
Theres alot more to it if your going with a custom system
. If you by a package when speaker and amp are supplied
together it pretty much plug and go not much to set up
besides tuning out in the dash setting. if its custom
you gotta make sure you running the right ohms nd the watts are correct
other wise the amp is gonna burn out, or cut off
its not rocket science. and its always good to go with a capaciter
and run a seperate battery depending how much shit you have tapped into
the power wires, other wise your gonna be drawing alot of power out of your battery thats running your car, thats where the diming of the lights come in
drawing that power
God i miss my system, it had gotten stolen a month after i got it
I had 2 12' AudioBahn AW1206T Flame Q series subs, with a 1500HCJ AudioBahn amp
ran em with 4ohms mono parallel setup, since its a duel voice coil, and that shit thumped
but that was the last one i will ever get, now in my alero i replaced stock speakers with polk audios

First off i didn't start a post talking about something I don't know
get your fact right.
second why ? my knowledge, dude im 25 im sure I know the more than just the basic and know how things work, otherwise I wouldnt be posting up shit, cause I would just sound stupid, but theres nothing I put down that was wrong. and your making it sound like I dont know what im talking about.
whats a capacitor? it's basically power storages in the car, and accumulate power whenever it is not required. This power is released when the demand for power exceeds the supply in your car. and also necessary to supplement the regular power supply of the car in order to ensure the smooth functioning of the amplifier, my opinion use a seperate battery for the supplement. so like i said If you car lights dim when your system produces a deep bass note, then your amp will be greatly helped with a car audio capacitor.
As for ohms,
All speakers produce a certain amount of resistance which is what we call ohms. Think of it this way Think of a water faucet. Open the faucet all the way more water comes out slightly close the faucet and the water will flow slowly or trickle persay. So lets use the water as an example of the flow of electricity(voltage and/or amps).And the faucet's valve that controls the flow is the speakers ohms(resistance). A speaker at 1 ohm would represent the water faucet being opened or turn up at the maxium or high level which a large amount of water would be flowing.The large amount of water would also represent the amount of power/wattage.Now a speaker that is 8 ohms would represent the valve turned down to a minimum level creating a smaller flow of water or "power" flowing

The only reason why your subs should be facing forward is if you plan to seal you enclosure off from the trunk. If not, you are just going to get a lot of cancellation and not a whole lot of sound pressure. (It will not be very loud.) Face your subs to the rear so they can load off of your trunk lid, then your amplifier will be fine on the back of your seat.

Best place for amps is as close to a good ground point you can get it within reason. Not upside down/inverted unless your amp is specifically designed for it. Also you dont want it tight against something else front wise- best leave room for proper air flow/cooling.
I agree, you cant just take any speaker to any amp,

Take notes, you need them.
Actually you can take any speaker and put them on any amp- doesnt mean it will function the way you want it to.
If you by a package when speaker and amp are supplied

besides tuning out in the dash setting.
Plenty of things to setup and things to do. There is proper amplifier tuning. There is adjusting filters. Its not all on the head unit... Dont forget aiming of subwoofers, polyfill in the box!!!
if its custom you gotta make sure you running the right ohms nd the watts are correct other wise the amp is gonna burn out, or cut of
Whats custom? not opening up a box and pulling an amp, sub, sub box and wiring out? That makes it "custom" ROFL
Of course the basics of Car Audio apply when you pick out your own equipment. I dont understand how the correct watts can burn an amp out or make it cut off? Maybe you can elaborate on that topic some.
and its always good to go with a capaciter and run a seperate battery depending how much shit you have tapped into the power wires, other wise your gonna be drawing alot of power out of your battery thats running your car, thats where the diming of the lights come in drawing that power
The basics of electricity will tell you that the battery is not powering the car, the alternator is. With that being said if the alternator is not supplying enough amperage to properly power the amp and the car, what makes you think that it has enough power to charge another battery or maintain a capacitor? It is this exact flawed thinking/myth which has plagued car audio for well over 12 years now.

whats a capacitor? it's basically power storages in the car, and accumulate power whenever it is not required. This power is released when the demand for power exceeds the supply in your car. and also necessary to supplement the regular power supply of the car in order to ensure the smooth functioning of the amplifier, my opinion use a seperate battery for the supplement. so like i said If you car lights dim when your system produces a deep bass note, then your amp will be greatly helped with a car audio capacitor.
Actually most of this is wrong also. Ya I know, go figure some random information copied and pasted around the interwebz could be wrong??? No its online it MUST be true!
It all starts with the alternator. If you dont have a proper charging system your shit is going to fail- its only a matter of time. Thats the bottom line.
Deeper you say? Fine.
Now once you are drawing over 125% of your rated alternator the brushes in the alternator start to burn. What this means is that if you voltage rail is sagging bellow battery voltage you will be burning up alternators. Adding more batteries only makes the demand on the alternator more. Adding more capacitors is almost worse...
More more more??? OK baby...
Capacitors... Well its short term storage. In what a capacitor can output in one second it takes 5 seconds to fully recharge. What does this mean you ask? Well it means if you have a demand that forces a draw from the capacitor then and the cap becomes depleted during this draw or one close by, the voltage will sag. It will make it worse because not only is the amplifier consuming power, the capacitor is recharging also. So its a double whammy.
Bottom line is alternator #1. Extra batteries help, but its a band aide. Capacitors- good when you have the proper charging system to back them. Ideally you would have all three. proper alternator, extra batteries and a nice cap bank for the transients.

As for ohms,
All speakers produce a certain amount of resistance which is what we call ohms. Think of it this way Think of a water faucet. Open the faucet all the way more water comes out slightly close the faucet and the water will flow slowly or trickle persay. So lets use the water as an example of the flow of electricity(voltage and/or amps).And the faucet's valve that controls the flow is the speakers ohms(resistance). A speaker at 1 ohm would represent the water faucet being opened or turn up at the maxium or high level which a large amount of water would be flowing.The large amount of water would also represent the amount of power/wattage.Now a speaker that is 8 ohms would represent the valve turned down to a minimum level creating a smaller flow of water or "power" flowing
anything else just ask
This again is false.
Resistance is a DC measurement weighted in Ohms. Resistance is a constant, just like DC power.
Impedance is an AC measurement weighted also in Ohms. What makes impedance different is that like AC current it is variable.
A speaker has an Ohm rated Impedance as the rating is variable.
What you call a 4 Ohm speaker is a speaker with an average Ohm of 4. DC resistance on a 4 Ohm speaker at rest is usually around 3.6 Ohm DC.
The water analogy only works in terms of amplifier output. A 16 Ohm speaker will sound the same as a 1 Ohm speaker providing they are powered the same at respective amp output.

The only reason why your subs should be facing forward is if you plan to seal you enclosure off from the trunk. If not, you are just going to get a lot of cancellation and not a whole lot of sound pressure. (It will not be very loud.) Face your subs to the rear so they can load off of your trunk lid, then your amplifier will be fine on the back of your seat.
Unless you're building your trunk as a 6th order enclosure it does NOT matter how you have your subs firing. Most people are going to push there enclosure up to the seats to have more room in the trunk, that alone brakes the deal. Never mind anytime you add anything inside of your trunk you will change its tuning.
What did I gain from sealing off my trunk, NOTHING!!!!, I only gain 3 db because of how I tuned the box that replaced the old non sealed boxes, I have the smaart metering to prove it.
Ryan, I love you.

I disagree Scott.
There is such a thing as aiming subs in trunks and I think it does make differences.
I have had subs in the trunk facing every which way. Ported, sealed and bandpass, including 6th order band passes. Moving them around can, will and does change things up. Hell I even sealed a trunk off before and noticed a loss.
I think the worse was when I put two 10's in the rear deck of a car, in a box per manufacturer specs. That was an epic failure and they were placed differently a day or so later... lol. That was my shortest lived setup.

Ryan, you are my hero. Recording Major here, and I fully understand everything you just said. :lol:
Could get technical about frequencies and acoustics and how it relates to speaker placement/direction and your vehicle. :lol:

I understand how it all works and all... With car audio, for some reason, I make it more difficult than it should be. :lol: I know what to do and all, but I still question myself. :rolleyes2: Probably cause I'm an audio nerd and think I could do better somehow....

my Alero is the only car I've ever had with a radio lol, never cared much about it (not like I could hear it in the truck anyways) and I would personally spend more money on engine work rather than something I would probably mess up/ never get done

lol I don't have to worry about it now.... I ride a scooter to work now. :lol: The only audio I worry about is plugging my headphones into my laptop. :lol: :yahoo:
Well, that and this little wireless PA system I've been installing in a small town close to where I live.... :lol: It's been one major PITA!!!
Pictures to follow shortly...

Regardless of audio OR engine, is anything EVER really done? :cool!:

I was wiring systems up while you were watching cartoons...
14 years in this. By no means was that serious. Even the newbiest idiots know enough to laugh at something like mounting amps outside to be "snow cooled" and patenting an idea like that.
:haha:
i had the jr circut builder and have been at it since i was 5 lol.. i built my first amp myself at 6 so who's got the biggest penis hahaha im going on 19 years and im 24 :scpimp:
everyones got an opinion right or wrong who cares lol just cause some people say a wrong term cant fight over resistance or impedance it is different but very similar and some people dont know the difference
