No Sound Comming from Amp

Hi, I have a DPX11500 Amplifier (this site didnt have it listed) that i bought last week. Today while listening to it, it cut out. Ill try and explain it as best as I can. In the middle of a song the bass dissapeared so i pulled off the road to take a look. The amp was still on (and showed no codes) however it was not producing any more power. I troubleshooted the problem as best i could and these were the results I came up with. Each driver was in good condition The load on the amp at the time it stopped working was 4 ohms. Each sub (alpine Type R) was 8 ohms and it was wired parrel. After checking both subs I hooked them up to my Kenwood 4 Channel amp and they sounded fine. So I tried them again on my Clarion, no luck. Upon a closer look the subs were actually moving, but very little and irregular. Its Upsetting this is my seccond amp (my last one was a KDC-X812D and I fried it running at 1ohm), so this one I thought I would be safe runing at the 4 ohms. Any Help you can provide would be very much appreciated.
