My totally hidden subwoofer install

**KUSoob** · #1: 05-30-2011, 01:46 PM

For those of you that want extra bass, without the lost of your trunk, this is your solution!

See this thread for details. http://legacygt.com/forums/showthrea...38#post1870838

The 4th gen guys have had these for a while, but I was the first box he made for the 5th gens, and let me say, it sounds incredible!

Line out converter

Amp underneath passenger seat (seat pushed forward to show, normally you can't see it).

This is by far the best option for a sub IMO. It provides REAL bass, unlike the underseat subwoofer and the HK sub.

Spare?

How come you have speakers in the trunk panel? I didn't know there are cutouts.. I thought It was 4x 6 1/2" in the doors and that's it?.... Did you cut those out yourself?

Yes, the spare tire is still under there, and Spider, the harman/kardon system came with a rear deck mounted sub.... but its very quiet.

Did you bolt the sub box in to the well, or does it just hold in there with gravity?

Any cooling issues with the amp under the seat? Have you run it hard for an extended period of time?

It's held in by gravity, and it doesn't move at all. Very secure.

As far as the amp... no known issues. I don't run it extremely hard as the sub provides a nice punch with little power, but overall no issues running it under the seat.

Not something I would do but that is a damn good idea, props. I just dynamatted my trunk (the spare tire well and base are) and noticed that the bass is much more prevlent with the stock HK sub now.

No props to me, they all go to Steven (ItalynStylion), he's the one who makes these. He did an excellent job on the box and is very knowledgeable about subs.

That looks like a really clean installation--nice!!

Did you have the h/k system? And if so, did you replace your head unit too? Or just the amp?

It looks like he still has the stock system. I noticed the stock amp was sitting under the new amp.

What is the cost/size sub?

**KUSoob** · #**11:** 05-31-2011, 06:35 AM

Yes, I have the h/k system. Didn't replace the head unit, just put in a mono amp to power the subwoofer.

Here is the sub I have: http://www.sonicelectronix.com/item_...-GTO1214D.html

JBL GTO 12" DVC, however I got it for $105. Looks like they've raised the price on it.
All said and done, the box, wiring, sub, and amp ran around $430. Pricey, a little. Worth it? Absolutely.

Awesome, I like it! How many cubic feet is the box? Was it shipped to you or did you pick it up?

I believe the box is ~ 1 cubic foot. Which is just enough for that Sub. It was shipped to me, he makes every box custom according to what you want.

I've had a few spare tire installs..

I love installs where everything is hidden.. What someone needs to do is make a fiberglass template/mold for the spare tire well..

It's a huge area with lots of potential airspace.. more than most cars..

If the installer didn't do it already, remove the factory sub and use that hole to allow bass to pass through... Yes you will notice a huge difference..

**20LEGGY10** · #**15:** 05-31-2011, 11:51 AM

you would need a rim to go around that hole. That would look pretty out of place with the sub missing haha
