Question 1

What harness do I need?

Accepted Answer

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!

Question 2

I'm still confused about what I need for my upgrade, can you help me?

Accepted Answer

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.

Question 3

We may. We're still adding products to our website. So please contact us with your vehicle information and we'll be happy to discuss what it is you're looking for.

Question 4

Do you offer technical support for your products?

Accepted Answer

Absolutely! We're here for you Before, During, and After the sale if you need support.

Question 5

How do you ship packages?

Accepted Answer

We typically ship domestic orders through the United States Postal Service (USPS) using First Class or Priority Mail services. Heavier orders may be shipped via United Parcel Service (UPS) or FedEx, depending. Tracking information is provided on every shipment except on First Class shipments weighing less than 3 oz.

We'll often ship international orders via UPS or FedEx, but may also use USPS depending on what seems to work best for the particular location the package is going to. International customers are encouraged to contact us in advance if they have a shipping preference.
