Alpine MRP-M500 amp

I'm going a different direction with my stereo and would like to sell my amp. It's an Alpine MRP-M500 class D amp with mosfet. I've had it installed it in my mada for 5 months. It's a great amp and small enough to fit under the drivers seat. If you have any questions just let me know. I'm asking $90 shipped.
