DIY: How to install the G.A.S E30 'vert subwoofer

[StereoInstaller1]

My 2 cents: Used cooking oil actually works better than bought cutting oil for cooling saw blades. Also I would try to cut holes from inside the cabin ( installer must be young and slim) Looks Good though.

Crisco FTW?

You cannot get to the area that gets cut from the inside: it is a solid metal wall.

POWER TOP GUYS!

Shoot me an email if you are ready, the model is here, the power top vert box will commence shortly. I have a few orders of other stuff headed out now, the slate will be clear to get this new design done.

OH! A NEW woofer gonna be available soon, too. Soundstream will be offering a fairly high power 8" that will work in this setup. I will have details as soon as it is actually available.

doesnt all that air driven by the woofers just hit the back seat? seams like you would lose most of the energy in the backseat?

READ THE GODDAMN STORY! THAT IS THE WHOLE FUCKING REASON I DID ALL THIS GODDAMN WORK!

Just kidding, but I am feeling a bit grumpy today.

No, the area behind the seat is actually part of the enclosure. It is the "vented" side of the 4th order bandpass that this design is based on.

Make more sense?

BTW, next run starts TOMORROW!

Get in on it, this thing rocks!

I believe he said 4 1/2" hole saw. Probably for the port tube holes behind the seat.

Hey Luke,

You mentioned that a 4'' hole cutter would be beneficial but didn't say why. I bought a kit that inclucdes the smalled one and a 4'' one. What do I do with it?

Thanks

Hi Luke, when the carpet goes in, is this supposed to cover the area where I cut the triangles out (with the triangles cut out in the carpet too...or do I trim this around the area the box goes?)

Any chance you have a picture of what the carpet looks like once it's installed?

Thanks

Jay

There are a few pics in the thread showing the carpet, Jay. It is only about a foot or so that you cover: it is purely cosmetic. Also, you don't want to carpet to be in the way of the air seal between the box and the triangles.

[QUOTE=Hey-U;3073074]Hi Luke,
I just found this thread. Looks like an excellent install. It seems to me that you mentioned elsewhere that this added about 50 lbs to the car? Is there a way to make this lighter? Nope, no way to make this lighter. I could maybe cut 5 or 6 lbs off and lose performance...no way.

You want a lighter car? Buy one that has a damn roof!

Honestly, I could not feel a difference with this car, and it was pretty well set up. For the bass you get out of this package, it is 100% worth it.

Are you offering an installed price?

Absolutely! Shoot me an email, let me know your timeframe, etc. I will do the labor for $350 on any normal 'vert.

Need to make sure you vert guys see this bump

Is there any feeling of reduced rigidity while driving assertively since you're cutting into the rear structural support?

None that I could feel. The car that we did this development on has a slight drop and billie sports, seemed to feel exactly the same, but somewhat heavier.

From doing frame work on multiple BMW models and my understanding of the structure on these cars. The cutting of those panels will not affect rigidity. The pieces cut out are hallow. And do not contain a piece of the frame or support. :D
