OK I have a couple questions, I already upgraded my head unit to a Pioneer AVH-P8400BH. First issue I have is that the stock Sirius/XM Satellite isn't working. I'm using the PAC C2R-CHY4
wiring harness, but something isn't right, as far as I can tell the Antenna doesn't hook up to the head unit, is there an adapter I'm missing?
Also, I'm wanting to upgrade the stock sub and have no idea what I'm getting into. Obviously I'll have to pull out the old Amp and sub, but I'm wanting advice on a new set up. I'm looking into doing 2 12" JL Audio 12TW3's (or similar) but I don't know what I'm looking for as far as a proper Amp to power them and the required wiring (possible battery upgrade) that I'll need to do.
Also later on down the road I'm wanting to do a custom enclosure involving the center console to house 1 8" Sub (Kicker CVR84) and want to know what I'll need to run that as well when I add it to the rest of the system
I know it's a lot but everyone's help is greatly appreciated
