I am having issues, subs are sounding weak and distorted when both RCAs are hooked up to the amp but if I disconnect one of the RCAs from amp then the one sub sounds wonderful and full. I have a pioneer 2 channel amp(GM-520T) and 2 Pioneer shallow mount 10" subs(TS-SW251).

Does it sound better if you undo either one of the rca's? Im betting you have your subs are out of phase with each other. Simply switch the positive and negative around on one speaker.
