Powers my MTX magnum 10's perfectly and bumps like hell. Much more clear and crisp than my old amp and it also runs pretty cool compared to my last one as well. Well worth the money, perfect for powering 2 10's

I recently used this amp to replace a JBL BP600.1 I had powering 2 12 inch RF P3s. I thought the JBL slammed but on a whim I decided to hook up this just to see and wow sounds just as powerful but more of a clean sound. 600 RMS from JBL doesn't sound better than 400 RMS from RF go figure. I love Fosgate and have been using there equipment for a decade. Can't wait to replace this with P1000-BD now!
