Well, I got the new headunit installed, its all wired up and working properly, even put some ground loop isolators to keep out the buzzing, but I noticed that the metra wiring harness (70-8112) only has RCA inputs for front and rear speakers, is this also sending a signal to the dash speakers and tweeters or do I have to wire something else for that, hopefully someone can help me out if I need to rewire them? Thanks, and heres a picture of the install:

 

The Rear speakers on a ES are controled by the rear outputs

the SIX front speakers are controled by the Front outputs

Front , Tweeter, mid and mid-bass are all connected together

with crossovers for the right frequencys to go ho the right

speakers. You can seperate it all and put your oun crossovers.

 

Ok, cool thats what I thought, Just wanted to make sure. Thanks man.
