Subwoofer Wiring

[MattismodderX]

Ok so this is my sub. below is the wiring diagram
http://img104.imageshack.us/img104/8569/rfp3212.jpg (http://img104.imageshack.us/my.php?image=rfp3212.jpg)

This is how it is currently wired (illustrated to the best of my abilities in ms paint) but ive heard that the way you wire it depends on the ohms and sound or w.e if so, my question is- is my setup correct in the wiring? if i change it will it make better/different sound? What way is mine currently set up??

Without knowing:

1) what the hell is that round thing between amp and speaker? Only 1 wire going to it?

2) whats the positive and negative terminal.

Gotta be a cap distributor block

the round thing was whats on the back/outside of hte sub box with the black/red pos/neg terminals or w.e off the top of my head i cant remember exactly which ones are positive/negative, but thats how it was when i got it so i kept it that way.

edit: you can kind of see how it look on the picture above. i cant find a good one up-close

[cherrington17]

i think hes talking about the big red circle above your sub, in the drawing.

if its a cap... your doing it wrong.

so what your asking is... whats the best setup?

we'd need info on the amp. what power, what ohm, how many channels, etc

[MattismodderX]

its a Boss 1000w max amp w. 2 channels. no idea what ohm its at, ill go snap a picture of it in a second. just gotta wait for my smoke break (work...ugh)

[AGT]

What sub is it. Go to site. Look for instructions. Log out of Aleromod. :lol: just kidding

[cherrington17]

its a fosgate HE2. 400w DVC (i have 2):lol:

[MattismodderX]

they're 2 12" 800w max (not sure about rms rating or ohm)
Heres a picture of all levels of the amp

this thread lacks information needed to help you.
are the subs each dual 4ohm voicecoils?
if so, i would go to crutchfield and look at their wiring diagrams so you can actually see how you should wire them as it is a lot easier than us trying to explain it to you. i would wire the 2 subs together at a 4ohm load and bridge the amp.

you said " i would wire the 2 subs together at a 4ohm load and bridge the amp" im not sure how to wire it like that, or what you mean by that

[MattismodderX]

Ok so heres the wiring diagram i found on crutchfield. the connectors on the actual subwoofer show 4 total, 2 pos/ 2 neg. thats on both sides of the subs i have (8 per sub).

[heineck]

put em in parralel.

[MattismodderX]

put em in parralel.

what do u mean

[heineck]

look here (http://www.termpro.com/articles/spkrz.html)

[heineck]

what you shouldv done is go witha 4 channel amp and power all your speakers and then run the subs in parrallel. but it all depends on if your amp can handle it

[lonnie]

put em in parralel.

what do u mean

look here (http://www.termpro.com/articles/spkrz.html)If that is how they are hooked up then they are in parrallel! This is good if the amp is stable and can support a 2ohm load on each channel.

[heineck]

they could be in series, i cant see through the box! lol like i said idk the specs on that amp

[MattismodderX]

going back to the shitty drawing i made in ms paint, the wires are connected to the 4 terminals in an X pattern, and the outside terminals on the one side are going to the box terminal, and then to the amp.


they could be in series, i cant see through the box! lol like i said idk the specs on that amp

This is parallel

[MattismodderX]

is that good?/bad? if i change it will it sounds better or would i be wasting my time?

[FrankTheTank]

just looked on crutchfields site, they used to have more diagrams than that.

[heineck]

with parralel your lowering the resistance and pushing more power thats good

[lonnie]

is that good?/bad? if i change it will it sounds better or would i be wasting my time?
This is good if your amp is stable at 2ohms on each channel. I assume you are running two subs in a box that are 4ohm DVC, so you have two sets of wires coming out of the box one to one channel and one to another...nothing wrong with this as long as the amp can handle it.

[AGT]

so does it look like this?
http://i59.photobucket.com/albums/g304/freezepoint/untitled-1.jpg

I sure hope not. Looks like a double head faucet with titties coming out. Plus I am not sure the wiring is correct

[heineck]

i was hopin sum1 would catch that i started out with a lopsided pair of tits

[MattismodderX]

basically when i look at the crutchfield diagram it only shows one side (ie: 4 connectors vs my 8) so does that mean i leave the other 4 untouched??

[itsbmw]

Assuming these are dual voice coil 4 ohm subs. These are your wiring options:
http://rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woofer_imp=4

you can only wire to 1 or 4 ohms, and I HIGHLY doubt your amp can run 1-ohm stable

[MattismodderX]

well all that looks and makes sense to me, but there are a total of 4+/4- terminals PER sub.

[lonnie]

well all that looks and makes sense to me, but there are a total of 4+/4- terminals PER sub.
Ok after looking at the pics above the way they are wired in post 21 is the correct way to wire them because they will be wired for a 2ohm load. If the amp can handle 2ohms per channel then you are good to go.

[Cliff8928]

well all that looks and makes sense to me, but there are a total of 4+/4- terminals PER sub.

They're duplcate terminals. The + and - on one side are for one coil, the + and - on the other side of the sub are for the other.

You can wire them that way as in the crutchfield diagram, however if you have only 2 terminals on your box you could also wire them up as a 4Ω load and bridge the amp. The results should be identical based on your amp's specs.

i love how there are like 4 different answers for this. its a simple question, that should warrent one answer and 12 agreeing statements...geeze.

[FrankTheTank]

just go with this configuration. each voicecoil has 2+ and 2- terminals to make wiring it like this easier, so you dont have to try to attach 2 wires into 1 terminal.

There is nothing above that says the amp is 2 ohm stable bridged...it is at 4ohms but I like mine being on seperate channels..but that's just me and I'm still pushing 300 watts rms to each sub at 2ohm load on each channel.

lol i know, half of me says alright that could work and the other half is like...wait mines correct? lol:blink:

hook it up exactly like buddy shows you in the pic..

stay with the 4 ohm load unless you invest in a powerhouse of an amp then ide run it 2 ohm

Thanks for getting us know where....LOL
