Frequently Asked Questions

Well, that depends on what car you have and the type of upgrade(s) you'd like to do. For example, if you have a 2012 G37 with the factory Bose system, and you want to add a subwoofer amp or powered sub to your car; you can type G37 in the search box and hit Search or Enter. That'll bring up the Audio Interface Harness Adapters for the 2007-13 G35/G37. You'll then see that you can choose either the Platinum Series (super high-quality) or Red Line (nice, more budget friendly) harness adapters. Choose the one you'd prefer, and then select Your Vehicle (Sedan or Coupe) and the Audio Upgrade you'd like to do, which is of course to "Add a Subwoofer Amp"! Once selected, the photo of the harness adapter for your car & upgrade will automatically pop up, so you can see what you'll be getting. Check the photo and read the description to ensure it matches your needs and the equipment you'll be installing. Easy!

Yes, of course. We just need to know 3 things: (1) The year/model car you have. (2) Whether or not your car has the factory Bose, Rockford, or Fender sound system. (3) And the type of upgrade(s) that you'd like to do (for example: add a sub amp). Simply contact us by chat/phone/email with that info, and we'll be happy to help you out.
