I have owned this amp for 1.5 years and never had a problem with it. This small amp is a great performer! MTX has spent decades establishing their reputation for great products, and this product is no exception. No, this is not a cheap 500w amp, But it puts out more-than-rated power, and never heats up if you give it clean signal and power. It has a small footprint so you can fit it in tight places (under a seat comes to mind). Over all, I am very happy with this amp and would recommend it to anyone with a modest setup if reliability/quality is more important than saving a few bucks.
