i have an ed amp/sub installed to my stock h/u. i used a wiring harness that connects to the rear speaker connector on the h/u that has line out and a remote switch (i got it from a guy on "another" scion forum but it looks like he's not making them anymore).

now i want to install another amp/new front speakers but i don't want to upgrade the h/u yet. so, taking into account i'm mostly a plug 'n play kind of installer, does anyone have any suggestions? (i'd love to find the same kind of harness that would plug into the front speaker connection on the stock h/u.)

thanks!!

 

Changing your front speakers shouldnt matter for any wiring, unless this new amp your talking about installing is for them. Am I right? Is the new amp going to power the front speakers?

 

yes. the new amp will be for the front speakers.

 

line out put converts are okay in the way of a keeping your factory deck or hooking up subs but for inside speakers the best upgrade would be a deck with front, rear, and sub pre out's!!!! the sound quality would be much better than using a LOC. but hooking a regular line out put converter is really easy you just need to know what is + and - on the factory harness for the front right and front left, and how to splice and tape.

front right + lt green - blue
front left + pink - purple
