I might not have the loudest sub, but I will have a clean set up here soon with pictures. I'm working on my install soon as the rest of the misc stuff gets here.
New setup will be:
Alpine IVA310 HU, Alpine S634 CD Changer, 4x - Alpine SPR-57C 5x7"s Powered by a Precision Power PCX440 amp, 2x - Alpine SPR-13S 5 1/4" Components in Custom Kick Panels Powered by the HU, 4x - JL Audio 10w1v2 (2007 Version) Powered by a Precision Power PCX2400 amp. The JL's will be located in: One Adrenalin sub enclosure under the driver side rear seat, One Probox sub enclosure under the passenger side rear seat, Two in a JD Boxes dual 10" box located behind the rear seat.
Again not sure if going to be the loudest, but should be very clean. Other misc items include, Optima Yellow Top Battery, Stinger wiring, Stinger Pro Hybrid 10 Farad Capacitor. (Might put either my XBOX360 or PS3 in as well) Its all in the works...
