Various HHR Sub Installs...

Almost complete. I shortened the wires and replaced separate fuse box and spliter with a combination unit. The speaker grill is Autobahn, and has flames that match those on the car.
Now all that's left-remove everything and carpet the board black, then get black carpet to replace the shoddy grey cargo mat. Then, I have to make the old speaker hole in the side panal square, attach a door, then carpet the panal and the other side black (so the door will be concealed). I will use a spring loaded magnet latch, so no knob will be needed. There is plenty of room inside to keep my cleaning kit-polish, glass cleaner, paper towels, etc. Eventually I would like to change the entire interior to ebony/black. Have to start somewhere, so it may as well be in the back

The system easily conceals behind the hats. But they still allow for airflow and cooling of the amps. The amps angle down towards the front of the car following the seat, while the hats drop straight down leaving several inches of space.
Remember-bottom cargo area opens, as well as the passanger storage bin. To access the drivers side bin, when the seat folds, the sub is attached and goes with it. If needed, just remove the headrest and the sub comes right out. Bass with the Infinity Kappa is so strong that it shakes the car, yet it is not overpowering.
I am proud to say that I have accomplished all of my goals-great sound while retaing all of the functions and relatively stealth appearance until I remove the hats.
To answer all questions.
No I don't have a spare tire. Took is out long time ago.
Yes its a sealed box. I took out my three 10" subs and put one 12" and a small amp. Wanted it quietier, but It's louder. go figuer
I used truck bed liner spreay that you can get in a can to paint it. that way I can put stuff on it and not scratch it up.Still need to sink the sub in and put a cage on it. Just waiting for my PG sub and amp to get here

I am using a single 2 ohm 10 inch Infinity Kappa in a .75 sealed box I built (with Dynamat Extreme and polyfill and everything glued and caulked). The box is small enough to fit behind the back seat and allow the rear compartment to open. At about half volume on my radio, the car ROCKS! Seats shake so much it is like a massage. Mirrors are hard to see out of. I could adjust the gain and settings on the head unit to get more thump, but that would make the music sound unbalanced. I really do not understand the need for anything more
Lee3333, that looks pretty good actually. creative, and still functional. fold-flat functionality for a large, flat load area unfortunately is ultimately lost, but you gotta prioritize what's important to you, as it is, of course, your car. i would suggest considering maybe carpeting the board the amps are on when you carpet the box too, just so it all matches. if you're already planning on it, cool, i just didn't see it mentioned.
Many thanks to you, Yonash. That was a great suggestion. Dont know why I didnt think of it. I have been planning on doing it since your post, but it involved a bit of work so I needed to allocate enough time. As an incentive, yesterday on 'Unique Auto' they built a sub rack/speaker box and they carped it to match the car.
Anyhow, here it be: (I still need to get a black rug for the cargo area to pull it all together, then finish up the side panals once I come up with a door for the old speaker area so it can be additional storage.)



Again, the bass is more than adequate, easily capable of overpowering the rest of the system. I am looking forward to April when the car shows begin so I can show it all off

Here is how it will look when I get the black carpet (Photoshopped)

No photoshop-I got bold and painted the carpet with Krylon carpet paint. Finished the compartment door also. Now all thats left is to carpet the side panals and door with the speaker box carpet. It is seamless, so the door should be totally hidden. No knobs are needed, as I used a magnet catch that swings the door open if you push it in the right spot.


It a Kicker CVT12 , mounting depth is about 4 inches. I bought the sub matched with the box. It is nice and thin yet still hits as hard as any other 12 i've had. ( in it's power range
