This refers to what kind of sound system the vehicle has. Premium audio systems are generally name brand systems (such as JBL, Bose, Rockford Fosgate, etc) that have been installed inside a vehicle when it leaves the factory. Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.
Standard Sound
Main Harness Function
Different installations on different vehicles require different harnesses. This type is what the harness is considered. Each wiring harness we sell serves a purpose such as installing an aftermarket car stereo, integrating an aftermarket amplifier with your factory car stereo, connecting Bluetooth to your factory car stereo, and more.

Don't hack your wire harness! Get this!

November 1, 2011

This made the install so much easier! This is a must have. Everything is labeled and the instructions/diagrams were very informative. No need to struggle with cutting,crimping,soldering, or heat shrinking in the vehicle. You can do everything comfortably at a table or workbench, then plug and play. Great product!
