Great value

They price matched from another company so I paid 99.99. Randy was awesome and helped order my entire system. I also price matched two mb quart components sets the xc1 216 for 132.00 so all four doors for 132.99. With this amp everything rocks.

Lots of power

Amplifier still works after 6 months. It does run hot. I had to install cooling fans to keep it from shutting down after about 30 mins of loud volume. I expected this with an a/b amp. I would buy another one in a second.
