I got a Subwoofer that I baught a couple of weeks ago which is 300 watts, and I wanted it to fit on my JVC car stereo. It has a White and Red wire at the back of the system for the Subwoofer output, but the wires are the ones which u usually put in the DVD video pins. SO if 2 wires come out of each vire which is 2, then I got 4 wires in total and then where does that connect to?? To the Amp or the SUb. Plus I got friend that has a 8" sub and works without a amp. ADVCICE WILL BE TRYED!!! rEMEMBRING i DONT HAVE A AMP, If u know anything how to hook it up, IT WOULD BE GREATLY APPRECIATED!!
