I have been out of the car audio scene for a few years, back when fosgate was the bad boys on the block with the Punch 200. I am rebuilding an SQ setup and am looking for an amp. It will be running MB Quart 6.5 comps and a Stryke AV12(dual 2ohm VC). I was looking at PPI PCX-4125, SS Tarantula 500/4, or a nice class D and keep my Punch 75 for the comps. What are the new top-end bad boy companies? I have a factory alt., but I am considering an upgrade, and I have a 1 farad cap laying around. If only my 225 had not been "misplaced", I would just run my old stuff. Any advice or suggestions would be great.
