Nice Amp for my Victory

I purchased this amp to install in the fairing of my 2013 Victory Cross Country Tour bike. I was able to mount it due to it's compact size onto an aluminum plate to help reduce vibration and aid in cooling. Connecting it was pretty straight forward with the proper wiring documentation. I used quality properly gauged wires and fuses and it powered up first try. I took my time setting the gain with my Polk DB521 and it has good clean sound. I have been running this amp for over a month with several longer rides and conditions and so far no issues. I would rate higher but durability will be key over time.
