Good amp

Good amp, I really like the fact its fan cooled when its needed. I installed this in place of a 2 channel amp and running speakers off a Alpine head unit with the bigger 27x4 rated amp. More power is better. Running everything off this amp and it sounds great. About perfect match for my 2 12" infinity kappa perfects.
Only complaint really is the plastic tabs that you mount it with seem a little weak but no issues so far.

Great Amp & Perfect Solution!

I recently purchased this to replace an (2) amps an Infinity 475 and 1300, after I lost a channel in the 475. It is paired with a set of Infinity 60.7's components and a pair of 63.9i's and I am adding a RF shallow mount 10" in the small space behind the rear driver's side seat in my 4dr Tacoma. I thought it would have similar performance, because it has simliar specs at 2 Ohms, but HOLY CRAP! This Amp is 10x cleaner than the infinity's, and is more powerful by far. The single amp has allowed me to reconfigure my system so that everything appears stock and I have not had to destroy any stock trim. I am absolutely thrilled, Thank you for allowing me to purchase this product!!!!

Amp does everything and then some

I replaced two smaller rockford amps, a 4 channel and a 2 channel for this amp. It is way cleaner and way louder. I am glad I bought this Amp. It is a little costly, but well worth it.
