Here is few pictures of my setup. It has 2 subs and three amps. all mounted out of sight (as you can see, or not see). The subs are, JL audio, old school 10w6 & 8w6. The amps are JL 450x4 & 2, 250x1's. I built the boxes according to JL's specs. They both fire down and sound perfect for my type of listening. The 8" and 10" subs, combine nicely to give a full sound of bass without overpowering the whole system. Also, the spar is still in its space and the targa fits like a glove. My main goal was to be stealthy, keep the spare and have a useful trunk.
