I just finished having my system installed today. I went with a kenwood head unit with the Ipod dongle in the place where 99% of you guys have your 4x4 knob Replaced the components with Ifinity Kappas. The back doors I had to use 6" and an adapter. I can't believe no one has done this yet but my amp (RF 8002) is in the storage bin under the cargo floor. Clean install, it's out of the way and no can see it to steal it lol. taking up my cargo area (for now, till I get back from Iraq and can build some side boxes) is my big box with two infinity 12" subs.

This setup totally deafens me when I drive with it turned up at all. Sounds great at normal volume levels. I'm totally happy with it. Can't wait to get rid of the big box in the back. I'm really impressed with you guy's ingenuity building those custom boxes on the side. Does anyone know how much volume you need for a 12" sealed box? I'd like to put one on each side like you guys did, facing inboard, so I still have room in the back for gear and stuff.
