So a friend of mine talked me into putting a system in my Cobalt. Considering I spend most of my work day driving around, I figured why not.

Two 10" 800 watt subs and 800 Watt Amp. Bought the wire harness, head unit , dash kit, etc.

It's all hooked up as it should be. Ground, Power, Remote wire.

BUT.... the damn Subs dont work!!! It gets power. The Amp works, but the "protection" light isnt lit. The fuses are fine.

I found somewhere that the original harness doesnt provide a Radio Accessory Switched 12v+ wire, that I have to wire into the steering column & use the brown wire.

I REALLY hope I dont have to!! My car = my job. And I'm no mechanic!

Anyone got any ideas?

OH! And the same "friend" who talked me into it is now "too busy" to help me with it. Figures!!!

 

sounds like your going to have to find yourself an accessory wire. Just get yourself a test light and prod around a little bit, you can find a suitable wire to tie into after a few minutes and use one of the inline splice boxes that dont require you to cut the wire, it simply bites on and can be removed if needed without ruining the wire. i had a similar issue working on my ex's 01 sunfire.

 

The switch remote or acc wire for the amp should be hooked to the new radio not to the factory wire. The head unit should have a blue wire for remote turn on and or power antenna
