Wet Sounds Syn6 amp problem??

[J2twenty5]

A couple of day ago my WS Syn6 amp shut off, no red blinking light..........nothing. Checked amp fuses and all in line fuses all in good shape. Hooked up another amp in place of it and works fine. Anyone else ever had any issues with this amp before, really love all of my wet sounds gear but this one has me scratching my head. Also amp is in dry area under the passenger fold up seat in my 2000 SAN.

Thanks
Jason
