I asked some time ago for any suggestions for a cheapish, compact sized, but decent quality amp to run (2) 200w rms 10's at 2 ohms. I ended up getting an MTX 421D R-stock amp for $100 and it kicks azz. I installed a stock GM 95A alt, a second battery hooked up parallel, and ran 2 gauge cable to it all, it's been running perfect for 2 months now. Thanks to those who offered their suggestions!
