The were selling some PL300 (i think that was the model number) a while back. I bought three for my brother to use. They are much cleaner than any HU amp, but they are far from great amps. Although, the 200 watts to the sub does pretty well consider he paid 19.00 each. At the price, they would be hard to beat, especially if you are on a budget. but if you are looking for high build quality/sq/longevity, look elsewhere.
