Video soon!


Okay guys, I thought I'd share my most recent build with yall. I work until 5:00 P.M. so please excuse the low light pictures. Most of the work was done at night. Ask me questions so I can make this a more complete build log!

Equipment: Two HDS215s, JBL GTO 1400.1 amplifier (1500w RMS @ 2 ohms), XS Power D3100 battery, Alpine CDE-123 head unit, Sky high 10ga wire for subs and 1/0 for power and ground. Stock alternator, and I still haven't done the big 3... I need to get around to that.. But my light dimming isn't too bad with this battery on only 1500w.

Rear chamber is very close to 6.3 cubes after displacement of port, and a small guess on how much fiberglass displaces. Front is an educated guess of 2.8-3 cubic feet.

Rear is tuned to 35hz, and front is tuned between 70-85hz. It's kind of a guessing game using the ski hole as a port.



This picture was really taken after my first botched attempt, but it lets you get the breath of the trunk before.


After some tinkering with cardboard, I got the shape of the interior where the wall will go and then cut this.




Then carpeted it.



And threw it in. It damn near fit perfect the first time. I only had to make some very small mods to it.



After getting it in, I sealed around it with "great stuff" to create a solid seal. I also had to build the box inside the trunk because of how large it was, so L brackets were also required.



Angle grinder to cut an 8" hole in the deck for the port.

After the floor was on, the walls went on relatively easily.


















I fiberglassed all of the corners for extra support and a better seal.

Some seriously perfect timing, my subs came in on my lunch break!


So sexy.



This is how I created the second chamber for the 6th order.


I went a little foam crazy, but you get it. Sealing all the holes up makes this an additional chamber in front of the subs, and the ski hole becomes the second port. (specs, tune, and cubic footage at top.)


Fix up the back.


Bulked up my electrical a little bit.


Seats back on. Hey you little SoundQubed! I see you peeking at me through that hole!




And that's it guys. Total cost for subs, box/building material, and battery was about $570. Subs were $105 a piece, battery was $225 used, and building material was about $135 for everything. I already had the amp and wiring, so I didn't have to buy that.

Nice. Would have been the perfect time for a fold down seat mod.

Omg! I just realized I have great stuff in my beard!


On a serious note, that's a great idea. The hard part would be giving it a good seal. After testing though, it definitely sounds better with the seats on.

Looking good, what does the rest of your system consist of? I had an infinite baffle setup quite a few years back, your front baffle with the foam sealer reminded me of it.

Everything you don't see here is stock bose. As loud as these subs are, the bose system keeps up. So I haven't found a reason to change them.

How hard are those arms and bars to work around? Im thinking of doing a "wall" with 4 10" mmats. I also still havent gotten around to the big three let me know how yours goes/went if youve done it.
