Wiring an amp an sub to my 2008 cobalt

[hockeyhall]

Does anyone know the wiring diagram for the rear speakers on a 2008 cobalt I want to wire my son a amp and sub, I have already purchased the line converter (I think that is what it is called) and am going to go to the rear speakers but don't know which is positive and which is negative on the speaker wires.

Also is this relatively easy or am I getting into a mess? I am mechanicaly inclined. Just haven't done audio in many years.

If I am thinking right it should be
Left Rear: yell. - brown +

right rear: lt. Blue - Dk. Blue +

As for amp turn on (remote wire) isn't much for switched in these new cars. I just run a relay and a toggle to turn the amps on and off in your situation. Awesome that the battery is in the trunk though...

Ok Thanks for the help.
I already had a three way toggle switch that I am running neon lighting off of two and used the third to power up the amp.
Let me ask you with the amp on it is a Phoneix XS2300 the power light lightly flashes with the beat of the bass and you hear a slight clicking noise at the amp is this normal?

Sounds like its not getting enough juice. The logo light will dim if its sucking to much current. Typical on most installs. Do the lights dim at all??? You might wanna check if the remote wire is dropping voltage also. Could be the clicking noise. If the remote turn-on drops voltage it could just be turning the amp on and off real fast. Hope this helps

Skory are you one of our resident audio specialists?

I do not believe so. I just got out of installing car audio. I was a shop Manager for the last 7 years... Now I own my own shop doing a bit of everything. Mainly air ride. Wouldn't mind offering a hand though.

Make sure you have a solid ground connection. If you have a multimeter (you can get a cheap one at Radio Shack or Sears), you can check to see if the power is dipping below 10 volts at the amplifier. If it is, you should look into adding a capacitor.

Also, make sure you add a 1-amp fuse to your remote wire. You don't want to run too much current into the remote turn on of the amp. Almost all amps are only designed to take in less than 1-amp on the remote terminal.
