Im looking for a 2-channel amp to drive my two fronts, Cerwin Vega VS-120's. They are 12-inchers with a 4-ohm impedence i would like to get by without breaking the bank. Would an AudioSource AMP200 cut the mustard? I think I can get one for around $270. Any other suggestions? I will be using a Pioneer VSX-D814 for my preamp and to run my surround speakers.
