check your ground scrap the metal then  rescrew it then if still no sound check the rcas  if in doubt run sum new rcas from the radio to the amp be4 hiding them  a custumer had same problem yesterday

Answer 4

Well, the way you describe it, the problem may be with the crossover on your amp.  If the crossover is set too low ( as many out-of-box amps are), it chops off any frequency above a certain level, and basically weeds out and doesn't send any signal above that set frequency to the subs.  Set the crossover to around 200Hz, and see if it works.
