Our 7" Chevy harness is designed to work with GM/GMC vehicles like a Traverse with a 7" screen or a Silverado with the Work Truck, Elevation or Custom trim level . It comes available in both style of harnesses, a T-Harness and a Loopback Harness. If you are planning on adding a sub to your Silverado we offer our T-Harness. You can add an LOC unit, like an Audio Control or Wavtech LOC, for a full plug and play set up.

If you’d like to amplify your doors or add multiple amps to your GM vehicle we offer our Loopback Harness. This was designed to allow you to keep using the factory wiring, NO cutting, NO splicing. Add an amp quick and simple without ruining your vehicles wiring or voiding your warranty.

Please verify the connector in the vehicle BEFORE placing an order. All Base Connectors that need to be returned, refunded or canceled due to the connector not being verified will have a Restocking Fee of $15. The connectors need to be in the exact same condition as they were sent in. Any damage or alterations made will void all exchanges and returns.

How your signal is delivered Matters !

Audiophile quality signal built with the highest quality materials at the best price! Zero to no resistance means les heat and a better signal.

What Is High Level or Low level?

High level : AKA Speaker level is an amp that can handle an input voltage of 8-40v. This high output is common in factory amplified vehicles or where the
max voltage of a head unit is more then 10v. This is normally identified by a pigtail connection point or via the RCA on the amplifier (must check user manual to verify.) Some amps have a switch for this. NOT all amps have this future.

Low Level : is 0-8v of signal voltage. This is most commonly found inaftermarket head units. or other aftermarket units that use can-bus. Most passive LOC units output 0-5v so they are considered a low level and are normally RCA to RCA. Modern day ACTIVE LOC units can output 0-10v of signal.

In conclusion an LOC works as an in line filter that lest you control the signal, its intercity and in some cases the playable frequency range.

If your amp takes a high level and it is within the vehicles factory output range then you dont need an loc unit and can wire in and out of your amp
directly. In some fords the signal can be flattened at the OB2 furthering the simplification of the installation.
