Great value

Bought the amp to go with my new Pioneer 7500 series head unit and new JBL speakers. Fabulous sound! This unit had much better signal to noise ratio compared to similar priced amps, including the JBL.

Hookup was quick and easy, connections well marked. No complaints.

Perfect

Great amp. I'm running it off of my factory head unit using the high level inputs. It's powering 2 JBL GTO638 6.5's and 2 JBL GTO428 4 inch speakers. Those speakers sounded good just using the head unit but when I added this amp oh man did it make them come alive. Pioneer makes great products.

Just what I needed

Bought this amp after reading tons of reviews. Want wanting to spend a lot but wanted quality. I have it powering 4 alpine type r 6x8s. It's in my 06 f150. Provides enough power, never even gets warm. Great amp fir the money.

Pioneer fm-a4604

good bang for your buck! Bought this to run a set of components, and they sound great! Crisp sound. Easy on the pocket, so I'd call that a win win! I'd recommend this to anyone who wants good sound, but isn't caring about huge wattage.
