This afternoon, I installed a Kenwood KAC-529S and 10" Sony Xplod sub. It took about two and a half hours because I had to un-bolt the front seats to get to the screws holding the trim down. I did that to install the power cable and turn on lead on the driver side, and the patch cables on the passenger side. That was the hardest and most time-consuming part of putting amps and subs in. Everything else was easy.
