hi i just wanted to know if stock cd player has rca plugs to run sub

Haha buddy, I wish.

Never that easy.

You need level line converters to convert the speaker signal to rca, But you can't really have that and the speakers running at the same time as you would change the resistance of the rear speakers, you would have to amp your speakers and have the sub going at the same time.

As far as I know. I was going to ask about a way to do this on Car audio australia, But I didn't really bother, I think I really need to get new speakers, and just amp the lot at once. Or at least amp one set of speakers, and add a sub, that would work also.
