I Need a decent low priced 4ch amp to run some PG RSD6.5 and some infinity 6822cf's ? MSALL or SUNDEVIL help if you can, Im building the same system as stealth but i already have the 6822's and want to amp them.

 

I think both would tell you to do away with the rear fill or just run it off the headunit because you want your soundstage in front of you. That would allow you to just use a 2channel for the front 2. And use that extra money for sound deadning and ur mdf for the baffles.
When i installed my ppi 6.5 components i was wary of leaving the rears unhooked, but ive gotten used to it and like it better.
