ok im trying to hook up to amps to my headunit and in the back of the unit there is four jacks for 4 rcas and an extra long wire jack for the rear speakers. now i hooked up my amp that i will hook up my sub to to the back of the unit and then i hooked up the other amp to the unit that will lead to my speakers not component speakers but regular speakers because i added more in there. so when i turn it on it sounds like shit. and the wire jack thats in the head unit is not used at all. does anyone know wats the problem and how to fix it. thanx it a pioneer by the way.
