I currently running ALpine Headunit. I want to go back with stock now How can I wire up amp and sub on stock Headunit? ANybody knows where info? Please Thanks.

 

You can do it, but it won't be worth it. You will have problems, it will sound like crap, and you will not be happy. You will have to buy a converter, and also cut your stock wiring harness. I strongly recommend you not do that. But if you have to, it can be done. Buy a high-level to low-level converter. It converts your high level speaker outputs to a low level RCA output to go to your amp. Again, please don't do this. It always sucks.

 

Thanks Crx Well I guess I'll stay wit no amp at all then .
