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 ****. 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.
