I'm trying to figure out how to power and wire a system that I've been looking at. Here is what I'm looking at getting. Alpine CDA-7998 (no preamp). Alpine SPR-136A (40wRMS-160wPEAK) in the dash and doors wired up to the front preouts. Alpine SPR-176A (50wRMS-200wPEAK) in the soundbar wired up to the rear preouts. 2 Alpine SWR-1241D (2x4ohm) or SWR-1221D (2x2ohm) depending on which one I need (both subs are 300wRMS-1000wPEAK).

What wattage/impedence amps would I need for this. I'd like to keep 1 sub on the right channel and the other on the left channel. How should I wire the 4 front speakers to get the right amount of power and impedence? I think the rear speakers will just be wired up like normal.

Does anyone want to offer some advice on what wattage amps I'd need and also how to wire for the 4 front speakers, 2 rear speakers, and 2 subs?
