Customer Reviews

Sean From Tampa, FL
Like everyone else said, this 4channel amp is da BOMB. I used it to power a set of Alpine 6.5 components and a 10" Type R sub. I had the perfect setup. WARNING, this amp is NOT WATER PROOF. My amp got a bit of water on it and well, lets just say I have to buy another one. Other than that, my next amp will be the exact same one :)

Anthony From Virginia
This amp is a great value and true performer. I have this amp in my Nissan Titan powering 2 sets of JL 6.5 XR's. They are clean and loud. You can't ask for better sound than what they sound like. Worth taking a strong look at.

Aaron From Raleigh
This is an excellent amplifier for the money. I replaced my Infinity 4 channel with this, and it is ridiculously clear. Mine came rated at 140 watts per channel, but I notice it is slightly quieter than my old Infinity, but that is more than offset by the sound quality and noise floor improvement. Also and excellent deal from OCS.
