Most aftermarket headunits come with RCA outputs (also known as phono) using this output use the last cable in your kit and run it down the side/centre of the car AWAY FROM THE POWER CABLES, if you do not do this then you may get inteferance on the sub.

If you do not have RCA outputs then you can buy something called a "line converter" This will convert the high outputs normally to your speakers and allow you to plug in the RCA lead. If you have to use this then dont do it on the cheap as cheapy line converters can sound aweful. And always use it as close to the source as possible.

If your still having problems let me know. ill even do it for you for free.

daryll illl take a look mate if you can get it out..prob need the converter though
