I love my Yamaha Pro amps so much that I am getting more.
I started out with a pair of P2500s amps for my bass bins, and a P7000s amp for my subs... I love them so much that now I am adding 2 P2075 amps for my horns, and 2 more P2500s amps for my surrounds. These are the best amps I have heard, and I get no fan noise at all (hate fan noise).
