anyone have a diagram or a walk through i need someone help!!!!

since my car is gutted aswe speak i might as well do this now too!

 

you need this box that taps into your rear speakers and give you aux outputs.

 

i have a dvd screen so i have aux ports!

but i think ill take the dvd back or something

 

Get an impiedance adaptor....I had to use one of those and i spliced it into the wires for the stock sub....

 

i know what i need just dunno how someone wired it to the trunk???

 

I wired the remote line to my brake light so it will come on when the night lights are on so I can run by switch at day and they are always on at night.

 

What exactly are you trying to wire to what? Are you trying to wire the amp or subs or both?

 

I don’t have a cobalt, but what you need to do is first run your power wire. Most likely you are going to have to drill a hole through the firewall, or you might get lucky and find one. Then you need to run the remote wire. I would suggest splicing with your power wire for your radio/deck. Next I am thinking that you will have to splice into your speaker wire from the back speakers, I don’t know if you can hook straight up through the radio, but I would doubt it, so just take your back/rear speakers out and connect to those, then you would run your ground wire to where ever, I don’t know how well you know subs, but all this would we wired into the amp and just use regular speaker wire from the amp to the sub, make sure you have strong enough wire for the power if you have big subs. I might not have gotten this all correct so please don’t flame me I am just guessing on how it would be for the cobalt since I do not own one, but this is how it is done on my car.
Also what kind of subwoofers did you get?

 

Our battery is in the trunk, no need for cutting holes for the power wire. You'll need to get a Line out adapter and short set of RCA's to plug into the amp. You should be able to use the stock sub's wire to get your sound signal and your remote turn on power. For the ground you could sand down to bare metal on a small patch in the trunk, preferrably in the spare tire well and sink a self tapping metal screw or better yet run a bolt through. or you could probably just use the negative terminal on the battery since that's where all the ground on the car goes to anyway. Shouldn't be too hard, but if you don't know what you're doing, take it to a pro.

 

Well that's quite nifty for subs having the battery in the trunk, are there no grounding screws in the back of that which came with the car then? Under the carpet maybe?

 

I never took the time to look on this car because I figured I would finally be out of the car audio game. There should be, the battery is back there. All those chassis grounds have to be connected to the most negative spot on the car, the negative terminal on the battery. I haven't really looked though, I just know the battery is in the trunk.

 

Yah I just wired mine straight to the negative terminal. I also think you can use a bolt that holds down the battery clamp if I remember right.

 

just tap the rear speakers and use a line converter. and wire them up to your amp and ur fine

 

I did ths when I had my prix. I had a line out convertor from Radio Shack and wired that into my rear speakers, ran a remote wire from the radio power source, and my power wire from the batt., the ground from my rear seat belt bolt and I was golden. Never had any problems.
