I need a good amp for my subs, and I would like to pick it up from somebody local. I'm looking for about 400-600 watts in either 2 ohm stereo or 1 or 4 ohm mono. I'm not looking to spend more than about 200 bucks as I can buy a JBL 600 watt mono amp for about 180 right now. I just want to see if there's anything else out there, so let me know. Thanks
