Amp failed

I purchased this amp recently and it worked good for 2 weeks, after that it started to fail. Amp always shows it has power but it would only work for a few minutes and then no sound, eventually I wouldn't get any sound at all. I did verify my system worked with another amp, so this MB Quart product was definitely defective. The other thing that I did not care for were the speaker wire connections. The wires connections are very close together and awkward to secure. The amp adjustments are made easily as they are located under a cover on the top of the amp. Crutchfield reps are always great and arranged for a return of the product.

Pros: Look of product Adjustments on top of amp

Cons: Product failed Speaker wire connections close together
