Does have either a webpage, or some kind of documentation that can teach me how to put a new cd player, subwoofer, speakers, etc in my car? Thanks
google is your friend. speaker and the head unit are extremely easy to do. you just pay attention as you take things apart til you can get to them (pictures help sometimes), then swap in the new equipment and put door cards, dash trim, etc back in place. subwoofers are only a problem when you have custom enclosures. other than that, you secure the box, run you wires (under the carpet is best) to the amp and head unit, and you're done.
