any ideas where to find help with sub and amp install? i'd just like to know a decent step by step, or where the shortcuts are, and where to poke through the firewall at....thanks

 

do you have warranties on your stuff? in that case doing it yourself voids the warranty. It voids mine anyway....

this is all i could find..

Which Mustang stereo do you have?

Simply installing stereo components will not necesarily void your warranty on your other stock stereo parts.

 

If a dealer told you installing an aftermarket stereo voids your warranty. They are liars, completly full of ****. If a dealer tells you that, sue them it's illegal for them to deny you service because you put a subwoofer in your car. Anyway to the original question, I don't know if theres any useful info on this site for you but I know I have found quite a bit for myself when I had some questions www.installdr.com

 

amazing site, helps a lot......
