My 89 Formula system
My 89 Formula system
I went with 4 Bazooka 12" subs, MB Quart 6.5" components, and JBL 6x9's. The sub amp is a Lanzar 225 x 4 and the rest is powered by a Soundstorm 170 x 4. Its an old Alpine head unit and Coustic EQ up front.
I just finished the install yesterday. Eventually I'll find out how it does. The Bazookas don't drop real low, but they have real nice punc. With everything being black, the pictures tend to come out dark. We'll see if this shot is any better.

That second pic is better. Looks real good. How many ft^3 is that box of yours? Looks like a good idea. Everyone else buts the subs in the well and the amps on the tank.

Sweet. Do you happen to have the plans to that box? Does the box go into the well? I might have to look into something like that. Whats better than a well box with two 12s? A box with four 12s

The box does not go into the well at all. With the hatch closed, the box goes from the back of the seat right up to the end of the glass. To access the well, you fold the seat down and slide the box forward a few inches. Then you have full access to the amps. The amp rack lifts out to give access to the cap, distribution blocks, and the wiring.

Now that I can see them, it looks great. Does the side panel still open?

The locking side panel does still open. In order to open the spare tire compartment, you just need to fold the rear seat down and slide the box forward. Then the plastic side panel can be opened for the spare.

that is cool....atleast you didnt try to hide them like most people...plus if your going to loose trunk space might as well go big...and your neighbors must hate u
Holy smokes, this is an oldie.
I didn't realize two years have past since I put my system in. It's not always wide out in the open like that. I built a cover for it so when the hatch is shut it just has black carpet over the entire hatch. As far as the Quarts go, they are awesome. I previously had 5.25" MB Quart components, so going to the 6" was just a slight upgrade. The Quart can play really loud and stay clean. I really like them.

I love those custom kicks!! How'd you build them? Got a diagram for them?
I was thinking of gutting my Bose kicks to do something like that--but I didn't really want to trash them.

Re: another shot
How much did the box cost you and long did it take for them to make it I was thinking of putting 3 12's in mine but this makes me want 4
Re: My 89 Formula system
The box itself is a pretty simple design. It's just a big square that's divided into four equal squares inside. It's made from 3/4" MDF, and then i coated it with spray adhesive and covered it in black carpet from my local AutoZone. I probably spent under $100 making it. It's got nice punchy, tight bass, but does not drop super low. That suites me fine since I listen to a lot of metal that has fast double bassing. If you're going for low bass or monster dB, you may be better served going with a different setup.
