I purchased this to power my 4 Alpine Type R 6x8s (SR68 I believe is the model number). Anyhow, they're very crisp, loud and no distortion. The best part of this amp if the RCA noise cancellation. My last amp picked up unreal amounts of ground loop noise, this amp COMPLETELY filters it out. In all, I'm pleased with the puchase, it's a solid amp, doesn't get warm, looks nice, sounds great and is fairly priced. Don't hesitate to buy if you're on the fence about powering components!
