Hello, first post but avid lurker. I own a 2015 volt with the stock (non-Bose) stereo. It has a pretty mean upper mid range bump that annoys the hell out of me (I'm a mix/mastering engineer) so I purchased a set of Morel component speakers and a 4ch amp with the intention of doing the instal myself. The last time I messed with a stock stereo was probably 20 years ago and it was a much simpler process but I'm a fairly competent tinkerer and good at following direction. Problem is, with all the stereo replacement threads on this forum I've yet to find one that specifies which wires I'm tapping into, color coding, etc.

My questions, however stupid, are:

1. Are there separate wires coming out of the head unit for the tweeter and mid-range or is it one wire going to the mid-range (door speaker) and the tweeter splits off of that?

2. WHICH wires, coming out of the head unit, go to the speakers?

3. I'm assuming the crossovers are best mounted in the door?

4. It's a fairly decent sized amp, am I going to have to mount it on top of the rear compartment?

Am I better off having a shop do the install and any ideas what that'd cost in LA? I hate paying for things I can accomplish myself unless I'm in danger of destroying the project.

Thanks in advance

Chris

coming out of the head unit is typical front right left rear right left. Full range goes to each speaker with a blocker at each speaker. I posted about my upgrade some time ago.

There are color codes of the wires coming out of the head unit on here somewhere.

I took output from head unit to speaker level inputs on amp mounted in center console then to crossovers mounted behind head unit and back to harness. I ran new wires to tweeters that i mounted in kick panel. I pulled 12v out of the fuse panel on passenger side. It was easy to do and if yo have ever performed any type of instal before you will have no issue.

I have schematics for getting the low level signals. They are front left and right, and rear left and right (just a copy of the front). If you've done an install before it shouldn't be a big deal. Mine was Bose, so I can't speak to what the non-Bose amp does, but the crossovers are in the Bose amp. If you don't have a sub (not sure what non-Bose has), there should be room under the floor for the amp (I took out the sub and mounted a signal processor there).
