Just bought a Magnum and I am going to upgrade the factory crap stereo and I was looking at the new RF Punch amps and I was wondering if anyone has used them. I heard that the 600.1 is stable to 1ohm and since I have 2 9kv2d2's I thought this would be a good fit and give me a decent amount of power at a VERY REASONABLE price. I was also going to use the 400.2 for the mids and highs. Any feedback is greatly appreciated.
