Pyramid Pb1617x 2,000 Watt 4 Channel (Bridgeable to 3 or 2 Channel) Car Amplifier with High Pass and Low Pass Electronic Crossover Network
I am not having any of the problems others are complaining about.  no cutting out, overheating etc..  It's about as loud as my 45w per channel JL audio amp maybe slightly louder. It's just a little less clear but overall sound really good.  I use it in my car on a daily commute and it's great.
