Awesome!

This product is very good! Even though you have to buy the wires separately. It makes my sub sound great!

Good output for price.

Amp powers a mb quart 10 with dual voice coil well, easy hookup and adjustment. Only issue is amp is mostly plastic, be gentle when mounting.

Crunch DRA850.2

This is a better than advertised amplifier. Even better than i wouldve thought. Ive never owned a Crunch amp but this thing rocks. very easy to install and sounds excellent. forget about what you may know about bargain amps, this thing is beast. i would buy from this manufacturer again.

By wil on October 21, 2016


Not too bad.

Purchased this amp to replace an older one. For its size it performs well. Installation is as expected when doing an amplifier with no surprises. Would recomend for somebody on a budget but still wanting descent power.
