Help with Sub outputs

ok first off ill say what all i got. ive got a Pioneer Premier 350 with front, rear and sub outputs. ive got a RF Punch 400a4 and a planet audio dual 4ohm 12. i bridged the rear channels,to my 12, hooked up the sub outputs into the amp and i didnt get any sound, so i turned the vol up and i could hear high pitched squeeling. so i turned it off and hooked the amp up to the rear outputs and it pounds. b4 i put my cd player in my truck i stuck it in my boys eclipse and he used the sub outs and they worked fine. i also got a RF Punch 75HD and i hooked it up and it does the same thing. so i wonder if the amps cant take the sub output signal? i really need help so if anyone can PLZ post.

BUMP

On some of the Pioneer head units, you have to go into the menu of the radio and turn the sub output on. They are turned off from the factory. That should fix your problem. If it is on then you have a defective sub out on the radio.
