Ok, I've finally decided to upgrade the amp on my 996 with a JL Audio G6600. I'm wondering if I can do it myself or should I take it somewhere to get it done. I'm very handy but don't have a schematic. Has anyone done a G6600 amp install on a 996 that can offer any advice before wires get snipped so to speak? I have the optional 6 speaker non-Bose system with DSP. I appreciate any advice or assistance any of you may have!
