Very pleased

Bought all Boston for the car and needed a single amp solution. This amp is amazing. Any type of music as loud as I can handle without dimming lights or any signs of it warming up. Perfect for the inverted under rear deck install. Can't put the quality into words.

AWESOME!

Ordered this Amp and when it came it I was captured simply by its simplicity. Then I installed it. AMAZING! The clarity in it caught me off guard. I'm hearing things I haven't before. My 2008 Jetta still has the stock speakers and this thing actually made those things sound like they're worth something. I will be upgrading the speakers soon to take full; advantage of this amp. 5 stars all the way

Quality Unit!

The size and weight of this unit was a little intimidating when it came to deciding where to put it. Inserting a piece of plywood under the upholstery on the back of the rear seat in my SUV created a secure and out of the way location. The wiring directions were easy to follow. The sound and performance have been flawless, even on the coldest winter mornings. Crystal clear sound at any volume. It's a great when a product turns out to be as good as expected. It's worth every penny!

GREAT!

Love the Amp, its inverted and completely out of the way. People don't know I have an amp until I turn the volume up.
