Here are pictures of how I built the first system. And it sure did come together...
These are the frames of my kick panels

These are the Kicker speakers,Two 6 and a halves and two 4 and a quarters. Complete with built in tweeters.

Check out the cross-overs
Here are the hideaway Kicker amps, Kx 800.4 and a Zr 1000, built and installed in the car. The 800.4 is for day to day listening and the Zr 1000 is the competition amp.
There's one in the backrest...
and one under the cusion.
Installed and ready to go

Here you can see, the single 8 inch Solo in the back.
The numbers are from this setups first competition.

I have two more boxes built, one for a Solo 10 and the other for two Solo 8s. Both can hit 140 dbs.
I installed the Solo 10 in April and changed out amps so expect more pics...
