amp hookup( please help)

i just installed my amp today and supposadly have all the wires(rca, speaker for sub, ground, power, blue power) hooked up right and the blue light comes on that shows that the amp has power and is on but i get nothing from my sub. i have no clue, i checked all the wires and still no output. any help please

perhaps the wires inside of the box have come loose either from the terminal or the sub.

Yes, make sure that you have the speaker wires hooked up correctly, and check your RCA cables, maybe try another set, I had something similar to this. Make sure your gain is at least turned up a bit, although I don't think that would be it.

yea i think it might be the RCA cables because i just put in new speaker wire and the ground, power, and blue power are fine, i might also need to check the wires in the sub.

if it is indeed the rca cables where could i find a good price on them online

i got 'em cheap from ebay. knu koncepts 4awg amp kit for 10 bux. i'm sure just RCAs are cheaper

yea i figured out that it was my sub that wasnt working and i have no clue how it broke.
