I have had this amp for over 3 years and no issues what so ever. It's a beast. I have used it to run 4 kicker rs6.5 components and it does so with minimum effort. Very strong amp.

I installed this in my 07 Altima, and have it powering MOMO MMC6500 components in the front, and MOMO MMC690 3 ways in the rear deck. This amp has great power, and the install was fairly easy.

I have this amp powering my 6.5 Polk MOMO's in my doors and my 4x10's behind my front seat and this amp gives them crystal clear sound even at high volumes. It sounds like a concert in my truck and it doesn't overpower my highs and make them sound distorted. This is a good amp that will bring your music to life.
