    Bought this to power the 10inch Kicker Sub I got for my car to add to my factory system. Handles the sub with no issue whatsoever. Best Buy did great job installing and was able to hid it away in my spare tire area. Great job.

    Good to pair with a 10 inch especially the comp r but underpowered for a nicer vehicle with a 12 tried both with amp and I’m impressed it handled my 15 well for a 400 if you don’t want to up to the 600 or 800

    Kicker is a superior brand. The quality of this amp exceeds all expectations. Its low passover and Gain and Bass Boost features are extremely fine tuned and precise.
