Audio shops; getting new head unit
 

Im planning on getting the Alpine 9831 Head unit. I know that after installing an aftermarket headunit, the left side audio controls wont work unless installed properly. I need to know which shop to bring it to so i can get the best install (excluding myself cause i suck).

Also, im in the market of the JL Stealth box cause i want a sub so bad!!! After the Head Unit and the Sub, im ready for the speakers and amp etc. I need it!

Please help
