I love this amplifier

I have this Alpine amp paired up with the JL Audio CS212LG-TW1 PowerWedge receiving bass signals from an AidioControl LC2i off the factory Harmon Kardon system in my Mercedes CLA 250. The amp is amazing and runs very cool compared to older amplifier technology. I have the bass control knob in the cabin to change the bass level for music from rock, to pop, to rap, to DJ Magic Mike (which is it's own category). This setup can can damage your hearing permanently if not used in moderation! I will be 50 in 4 months, grew up on rap, and competed in car stereo contests when I was younger. I can verify this amp is super clean, with PLENTY of powaer. Spend the money because you get what you pay for.
