I know this subject comes up a lot, so I thought I would chime in. To any interested in keeping their stock deck and adding multiple amps and subs, Navone Engineering makes some great stuff. I just finished an install using a line level converter and remote trigger source. All work great with NO NOISE (no alternator noise, no distortion, no turn on thumps or pops). I would highly recomend this guys stuff to anyone. Many thanks to those who suggested his equipment!
