I have bought a new Alpine SWR-10D4 for my car and would like some opinions on amplifier options. I am looking for something with enough power and decent sound quality. My budget is around 250 or less for the Amp. I am running a sealed box and looking for low and tight bass. I would like to know if anyone has bench marked these amps and to hear any hands on opinions. I am open to any amplifier suggestions though. I would like something that can produce 900w rms +-100w without reaching 1% distortion. Any Suggestions?
