Sony Xplod XM-554ZR Car Amp

Lets start off I'm not stranger to car audio and have owned many amp's in the past including Kenwood's and Clarion's. The amp in 98 bucks at Walmart, and it works how an amp should. I just did a whole install in my latest car with polk db's and the sony, fed with low signal outputs from the head unit. Nice good clean power from what my ears hear. It has high and low inputs, and high and low x-over's. It has no bells or whistles but am very happy with it's performance, without a doubt would buy again with no hesitation...that's the bottom line.
