audio setup from scratch (techno/trance/bassy fast)

[StereoInstaller1]

damn!! that's pretty nice! I wonder how much it weights? Did you only use glue? what kind? (woodworx... is that it?)

Dude, that is some nice work man!

When I build, I use 3/4" MDF, a quality wood glue carefully spread for best adhesion, and I use a 1/4" crown air stapler, with staples that are 1.5" length. Generally, the boxes I build cannot be broken at the joint, even using a sledgehammer.

As far as weight, my setup is pretty big. I am using 2 600 watt Exile amps, a 2 channel and a 4 channel. I would say the total weight is about 80 pounds, maybe a bit more. But, I am looking for some damn big sound...ask the guys at the Picnic!

I am doing a thin Exile XTEC 10" (single 4 ohm) in my GF's '89, ported through the ski boot hole. I am not too sure how things are gonna turn out, but she needs her trunk space...and I intend to integrate a strut bar into the design.

Here are the design goals:
Useable output to below 25Hz, over 125db
Less than 8" depth (measured from the bottom of the trunk)
100% sealed into the cabin
Less than 55 pounds, being the same weight as the trunk tar

Custom fabricated strut bar will be through a tube running inside the box...not quite sure how I am gonna do a strut bar in the same space as the woofer...but I am pretty stubborn about the whole thing.

Sorry for dumping this all over your thread. Seriously jacked up on coffee this morning!

Sealed cheap sub if you just want some bass and not a lot, i would suggest maybe a MTX 5500 10". But i am MTX for life, my sub has never let me down for the money i paid for it, cheaper then most, great sound quality, and very forgiving. I also am a pioneer fan, so i only use pioneer decks, but for speakers i would suggest you go with some component speakers and a 4 channel amp. If you really want, buy the MTX 5500 10" in the ported box, sold out at most places and cost more then the 5500 15", and i know why it's so expensive. It is almost as loud as my 7500 15" but it has great sound quality.

I make certain that the entire output of the subwoofer is 100% sealed into the car...but I prefer the sound of ported boxes. I have the ports run into the car through the stock rear speaker location...since I have no rear speakers.

Currtently running a single Exile XP12. Could not be happier.

Here is a shot of the woofer in the box. I wanted the face of the woofer to be vertical so when I do the window in the back of the box, the magnet is paralell to the window


Here is how I did the porting, which is HUGE compared to how normal people so ports. Larger surface area needs longer tubing to achieve the same tuning...so 2 X 4" ports in my 2.4 cubic feet is about 30" long.


Almost anyone with a decent tablesaw and some skillz can build a box...give it a try!

Yep, sub facing the cabin. Works well even if there is no center armrest. Well it did for us, we're no bass heads.

My take on e30 and subwoofers:

sealed box 100% sealed against rear wall/cutout is the way to go.

what do you mean by that? Sealed against meaning sealed in the trunk facing the rear cutout?

Thanks!! that looks like what i need!

[Mless5]

I can prolly do ~$700 for the whole setup (installing all by myself)

I should correct myself. For the speakers, I ment $100 for one set... not for all 6!! LOL

You want great sound, cheap?

Buy a CRX.

No such thing as good cheap sound in an E30.

Your best bet? a single 10" in a ported box, a 4 channel amp running it and the front "Premium Sound" speakers using aftermarket crossovers. No rear speakers at all.

If you shop carefully and have box building skills, you could do this for about $350 using all new stuff....assuming you alreay have a set of premiums.

[PУCCKAЯ_e30ka]

speakers should not be more than $100. Keep it stock, I don't wanna go "show" just some nice sound. Weight... well, I think that would be regardless of what I would get anyways... thanks for your input thought!

[Mless5]

Any restrictions in $, space, weight? How far are you willing to modify your car?
