Poor Power

This amp is extremely underpowered. It only does around 30watts RMS @ 4ohms per channel which is well under what it is rated for. Another thing I dislike about this amp it that all the channel terminals are over one another making it difficult to wire. With all this being said, the amp works but I only recommend it for two channels not four. With two channels only expect to push about 40watts or so per channel to leave some headroom. My advice, save up and buy something better that will actually perform as stated.

The price is right

I needed a 4 channel amp to upgrade my system but didn't want to spend a ton of $$ so I purchased the Autotek. One of the main reasons I bought this amp was because it had the preouts that allow me to run another amp for my subs. Not the most powerful amp I have had but for the price, it'll do!
