MRP-M500 - Alpine Monoblock 500 Watt RMS Power Amplifier
I bought this to power an Alpine Type R 12 (1223d) at 2 ohms. This amp is small, lightweight and unobtrusive. I was weary of the unit being able to actually put out 500 watts, and worried that it would get burning hot if it did. Not the case. I can smell the voice coils on my sub from pushing it so hard and this amp never falters. It is always cool to the touch, even after an hour long bump session. Amazing. My only complaint is that it is meant for 8 awg instead of my 4 awg, so kinda' difficult to hook up
