I dont know jack about amps or subs as far as the technical stuff goes. I did, however, hook my system up. My question is, my subs stopped working. I think i have it narrowed down to the amp as the source of the problem. I have a cheapo amp from radio shack, i am getting power to the amp, cause the power light is on, but the light that says "protection" is not lit. I checked the fuse, not blown, replaced it anyway, still not working. Any sugestions? or is my amp fried? Thanks guys.
