I got a 99civic ex coupe and i was wondering about how i wire the front and back speakers they have 4 wires going tho them is tehre some way i could cut and splice or do i hafta run new lines?

 

The fronts have 4 wires because 2 come from the deck and 2 go up to your tweeters.

I've never seen a Civic with 4 wires on the rears.

You could just get the speaker harness adapter plugs and not have to worry about how to hook things up... Just connect to speakers and plug into factory plugs.
