hello all... i have an 800w xplod amp that i was preveiously using with a 10 inch sub and a headunit. i am hoping to install it in a different car with no head unit... i just want to use the rca inputs with an ipod. my question is can i wire the outputs to 2 speakers and the same 10 inch sub or do i need a seperate amp for the sub? there are only 2 positive and 2 negative outputs on the amp. thanks.
