    I bought this amp through a different site and it sounded amazing until 2 channels went out. Not sure why but they did. My old cheap mtx works like a charm still so not sure what happen to this one. I'll try alpine 1 more time because they sound great for the price.

    This amp was the perfect addition to my car audio upgrade. Alpine class D really packs a punch. This amp also includes wire plugs for very quick, dependable and easy installation. This was my first purchase through Onlinecarstereo.com and it most certainly will not be by last. Excellent prices, great service, and very quick shipping. Next purchase = 2 sets of component speakers.

    Hook up was extremely easy. The sound was very clean. Worth the money.
