Ported Trunk 2

[AleroDrime]

for clarity im not talking about ports for my box, my box is ported
nor am i talking about ports running from the box elsewhere
and this is basically a cosmetic question

original post

I have two 3in ports, identical to the ones that were in my bandpass box, and I want to port the trunk. My original plan was to do this through the rear deck. But the metal part underneath and roods are keeping me from doing this.
I'm asking your opinions on placing the ports though the center of the rear seat. This means relocating my large amp but i beleive there would be a lot of benefits from doing this. Such as more bass in the front of the car and releived pressure in the trunk, less rattle and less hazard to the 6x9s.

I want your honest opinions on this mod, please leave opinions about me out

basically
do it through the center of the rear seat one over the other

or in the rear deck between the 6x9s

another thread ? :rolleyes2:

are you freaking for real ? :coolio:

or are you just playing this role ?

effin troll

For one thing, you don't necessarily need to use 2 ports, maybe only 1. Also, this whole project is going to involve trial and error, since the volume of the trunk vs the port diameter and depth will affect the tuning. It may turn out that the tuning is at too low a frequency, who knows?
Anyway, I vote rear deck.

[AleroDrime]

the other became a crap fest, too many pple had noclue what i was asking about(like most my threads)

i dont think tunes gonna be a big deal, we are just talking about holes in the trunk, basically i bought two ports to use so it'd look clean

[jayson_waltz]

just leave the rear seat down? thats wat i do and its lots easier than this.

[AleroDrime]

i want ports and cant have the seat down all the time

[KenshinZero]

N/M misunderstood. >_< PLUH Are you having a problem with hearing your rear speakers?

[Ryan from Ohio]

Two 3" ports?

You are toying with things outside your capability. What you will be doing is making a bandpass box...

To avoid this, make the openings as big as possible.

two 3" ports is hardly worth the effort IMO.

that is what i told him in the other thread :rolleyes2: sure we will see a third thread :rolleyes2:

[worknprog.99]

just remove the whole back seat... bondo over your door creases shave the rear door handles and make it an extended coupe. then put a glassed box in the back where the seat was. and put your amps in the trunk with the speakers npw filling the whole where the seats were.. just make sure you learn to do body work before you shave your back doors to create a coupe... thus now you dont have to worry about poeple sitting back there...

[AleroDrime]

lol i wanted a coupe to begin with but couldnt find an ecotec coupe anywhere near my area. ryan how much opening do you think itll need, and overall acoustically is it a bad idea

and while he is @ it why not make it a convertable.

[worknprog.99]

i told you the opening size. remove the back seat and convert to long-coupe

[AleroDrime]

can yall be serious im not turning a sedan into a coupe, nor am i removing the back seat mess from a sedan

ive been serious about this idea for a while and i really want experience input on how to do it right
my friend ran and got two 3inch hole cutters(sry bad with proper names) just so if this works we can do his sentra

[AleroChick785]

they are givin the advice they have...ur the difficult one in this entire situation

[worknprog.99]

yoou were serious about making an extended cup holder sub box thing too and that failed or never was even going to happen... how do we know when an idea is serious and when you just are shooting the shit?

[YALEROYNOT]

lol i wanted a coupe to begin with but couldnt find an ecotec coupe anywhere near my area. ryan how much opening do you think itll need, and overall acoustically is it a bad idea

its a calculation you need to do and like i said on the thread.....:rolleyes2:................ you should seal the box off from the trunk and make a band pass.... using the trunk as a chamber it is to big unless you are putting 2 or 3 18" in there

[YALEROYNOT]

its a hole saw

and take a video so when you pop thru the metal and in to the rear window I can see it...... dont forget your safety glasses

What About The Extended Center Console Speaker Thing Project!! Finish It Now

[AleroDrime]

ryan and yalero are the only ones i really am seeing any actual advice from, the idea of turning the sedan in too a coupe is ignorant and would never go over well with my family, (its my car i make the payment but dont do the insurance).

i wanted to use the ports so itd look really clean, however, if you could give me some dimensions (itd be harder too) id be willing to try a slit in the back behind the 6x9s, maybe 2 inches wide and about the width of the rear deck, that way i could cut the carpet there right and glue the carpet under the edges and give it a clean almost factory look

do both, why not? since what everyone is saying that two 3" holes will not be good enough, then go with four 3" holes, or maybe larger.

[AleroDrime]

What About The Extended Center Console Speaker Thing Project!! Finish It Now

it got scrapped, like i said a while back, its just a stand now for the frontend loader on pops tractor
im currently thinking of using that plastic bondo filler mess there and removing those two holders all to get there if i cant find some kinda oem looking strap to go on the open part of the holders

here we go again yall are mocking this instead of helping me do this right, except for yalero and ryan

yalero, is there a way to do this without the trunk becoming a hugely unproportioned bandpass box?

[colonel6632]

i think the only way to make the car sound like it would with the back seats down... is to make a hole about the same size... try moving your subs around... have them face towards you and pushed close or pushed to the back of the trunk... all of that makes a difference... i cant stand my car with the seats down normally... waaaay too much bass

[Ryan from Ohio]

The bigger the better.

Nothing will be bigger than the two 6x9 holes.

Thats all I can say.

Catch the drift?

Anything short of that is futile.

[AleroDrime]

and take a video so when you pop thru the metal and in to the rear window I can see it...... dont forget your safety glasses

the plan against that was, while he drills ill push down on a 4x4 wrapped in a towel(to prevetn scratches) that way we hit wood instead of window

[AleroDrime]

ryan if i could fit four or possibly five, how much less of a bandpass would it be, although 4 and 5 chrome ports would be kinda ridiculous looking, what do you think about the slit idea

[worknprog.99]

use a short blade... or cut with the blade going into the trunk

its a little too much with mine down too but i figured smaller openings was a good idea

[KenshinZero]

How often do you have 3 people in the back seat? if you hardly have people there, why not cut an opening in the middle of the seat? People could still sit in the middle, better yet make a hatch in the middle, when there isnt 3 in the back, open it, if there is you can close it, man im SMRT!!!

sry the back seat is needed for family issues, i really dont want to explain it on the site either, but can we say that my car having no backseat is not an option

sry just re read that i could put cup holders there too i might consider that but ill have to look around some hardware shops at door hinges, but id still like something i little more professional looking

i think smurf or afungy suggested something like that minus the centerhatch

[worknprog.99]

what about removing the top rear deck and glassing a cover with the ports in that?

[AleroDrime]

wayout of my skill level is why, seems like itd be a much harder task for me, probably alot easier to and experienced person

[worknprog.99]

you wouldnt have to remove the whole thing. just like in that one picture in the other thread. maybe not glass but wood covered in matching carpet...

[AleroDrime]

if anyone can come up with a way to make the edges, of the holes look clean, cause if i did do that, id move the 6x9's and the covers to the rear doors

[worknprog.99]

no i think that is out of your skill level

[AleroDrime]

some kinda rubber lip mess?

[worknprog.99]

no glassing a door panel to alow the space for the new speaker.. and re routing the wires

so the kid who was sooo broke like a week ago, and refused to drop 35 bucks on a shifter console wants to go down this road?

dude this are the only nice words imma tell u evar, aaron your wasting ur time and ours, so drop this shit and port your 1/4 panels.... ask bdyman hed looove to walk you thru it LOL

[WhiteV6]

Wow. The w bodies have the rear arm rest open up to the trunk (option?) and that was awesome for my sealed 2 10" box facing towards the back from the rear of the trunk. If you want the best sound, you need to experiment. If you wanna be a forum whore, you create multiple threads asking what others think you should do. More hands on, less hands on the keyboard.

[Afugy]

Please stop calling it a port,,, call it a vent or a hole. When people hear port they think sub box. Ports are tuned and increase the efficiency of the sub, your VENT will do non of this. Nor will your VENT stop the rattling coming from the trunk.

[Ryan from Ohio]

If you are thinking of moving the 6x9s into the side wells of the rear plastic DONT.

6x9s blow nuts.

If you want to do this get some decent 5.25" or 6.5" Mids. There IS room.

Simply cut a hole accurately with a jig saw, dremel tool or butter knife. Then use the included grille covers. Or get some grilles if yours didnt come with any.

i know the vent will not stop the rattling, thats why the car willl be dynomatted how ever vents like these should help alot with other issues, such as pressure

lol that was the around march, since then i scored two jobs, but now im back with no job, i dont think this project could get costly, all it really is is skill intensive, what im doing is trying to ask experience pple like ryan how to do it and get it right

[GA_turbo]

well i guess there are only 2 solutions, either you take out the 6x9s or get a louder system so that way you dont have to have the seats down then.

[AtomicX]

Agreed. I don't ever need to put my seats down with mine.

Upgrade your sound.

[meadus101]

I think if you put the two vents in a vertical line through the middle seat, it would look awesome.

It wouldn't be that comfortable for people sitting there, but oh well.

[worknprog.99]

where are progress pics drime?

[mach3]

Wow, like 7 pages of discussion on this topic, with numerous suggestions from simple easy to do all the way to hacking up you car. Here is my honest opinion, what you're doing is a waste of time for how little benefit you're going to get out of it. Personally I would revamp the whole thing to get it right rather than, using band aid solutions. Just my 2 cents.

I'm not try to discourage you, please don't take offense to what I said. It's just my opinion.

Good luck with your project.

[Bad99Olds]

My vote would be what a lot of people have said, make the system louder so your not cutting holes in things.

[worknprog.99]

^^^ i second that. just sell the current setup. invest in some sound deadening stuff for the rattle and purchace a harder hitting system

[Bad99Olds]

Upgrading equipment>>>>>>cutting holes in shit

[Ryan from Ohio]

The simple upgrading equipment rather than porting the trunk to cabin is a flawed and poor response.

The bottom line is the 6x9s need to be removed from the rear deck of a car when subs are in the trunk and the seats are up.

The reason is the pressure (both ways) involved with the subs. When the sub extends and presureizes the trunk, the 6x9s are forced to extends also. Same is true when the sub pulls back.

This actually causes the 6x9 to over extend. If power is applied to the speaker while this is happening it causes issues.

Now if your port the trunk and do so with say, 2 3" ports through the arm rest as mentioned- then you are creating a bandpass box. The same issues I mentioned earlier will still be a factor- besides the weird tuning this will create. The reason behind this is you are actually going to use ports that have an influence on the subs. The reason removing the 6x9s wont have an impact on the subs is because it will actually create a tuning point well above where the subs operate.

Now that Ive sunk so much time into this response I hope its crystal clear to AleroDrime and the others who commented.

:ninja:

[AleroDrime]

i know, sometimes you can hear them warping, how well do those "speaker condoms" work

[Ian 2000GL LA1]

check out the build logs in my sig. imo the back seat is not going to be the loudest. im going back in the trunk with an 18" if im keeping my 10K amp and batteries.
