Anyone have ideas? Post them up! Heres a couple Ive seen.

 

How about sumtin like this. 1 10's and 2 8's but I believe it should work with 12's as well. These pics aren't the best but I will descrobe as much as I can. Behind the 3 subs, there was a lower portion where the 500/1 JL amp was mounted basically on mirrors so show the 2 JL AMPS mounted under the rear deck. It looked pretty trick in person!!! For you project, you may wanna drop the 12's where the 8's sit and place the amp where the 10 is maybe behind etched and backlit plexi. The the area closest to the seats maybe you can put the capacitors, on either side of a nice colormatched nitrous bottle!! LOL Also you may want to place the wires under clear plexi too and showcase them if you lay it out nice. I think most peeps hide em, but it may be cool to actually show a very meticulous wiring job!

Good luck with it!

 

That does give me a couple more ideas, thanks.
