Ive got an Infinity house sub and ive been able to isolate the positive/negative wires coming directly from the woofer itself. in my car, ive got an amplifier with subwoofer hookups, and ive got a positive wire, a negative wire, 2 RCA connectors, and a ground. to use the sub in my car, do i just connect negative to negative and positive to positive or is it more complicated than that? please be detailed, thanks 
ive already checked the power ratings/ohm ratings and such. i just want to know how to connect the sub to my car stereo.
