Our Bose Amplifier harness is designed to work with a variety of GM/Cadillac vehicles from a Silverado, Escalade, Sierra and any GM vehicle with the factory Bose amp, including Cadillac and Buick. 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 Sierra we offer our T-Harness. You can add an LOC unit, like a Wavtech LinkDQ, for a full plug and play set up.
If you’d like to amplify your doors or add multiple amps to your Silverado 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.

Our harness throughout the years has evolved into what we call, and are currently in the process of patenting, our Elite Series Harness. This option is an all-in-on solution for the ultimate DIY’er.. After 7 years, developing our own wire and combining LOC’s, processors, DSP’s and companies like Audio Control and Rockford Fosgate, who offer amplifiers with a high level input signal. By combining these top shelf solutions for the 12V market you can get an entire system upgrade at the same price of a factory head unit upgrade alone.
When choosing an LOC it is important to know if one is even needed. Especially if you already have your own equipment. Look at what the parameters of that equipment are and if the amp takes a high level. For example some mono-amp’s cant take above 5V of signal input. When using a Wavtech Link2 or an Audio Control LC2i Pro you want to verify the signal output does not exceed what the amp can take.
It is recommended to verify if the vehicle has Active Noise Cancelation (ANC) before placing an order. You can do so by checking for the microphones in the headliner, above the rear seat. With aftermarket subs or speakers the ANC microphones create a feedback. To avoid the humming or “pop-like” sound from happening we offer our Bose ANC Bypass. This plugs into the Bose amp as the diagram in the pictures will show.

The question is always what is the difference between the T-harness and the Loopback and the simple answer is, the T-harness is ideal for adding a Subwoofer only/mono amp or in a situation where you plan to run your own wires from the aftermarket amp to your new speakers.

Our Loopback is simply the best option for any installation. Not just do you get the SIGNAL from the factory source unit but it also comes with 12v DC +/- to power your LOC or DSP. It also have a RETURN side that feeds from your aftermarket amps output, back to the factory speaker locations via the factory wires. The Loopback can also be tied together at the end, closing the loop in essence making a T-harness so you can start small and grow without needing to buy more.
Our S.I.K kits were the first of their kind to ever exists in the 12volt market. A solution long needed but never provided, you need new speaker wire was always the answer. That's no longer true. Increase the output and performance of your factory system in under 30 minutes. Our design places the aftermarket amplifier in the middle of your Elite Harness System.
Take the factory signal modify, tune, amplify and right back to the factory speaker locations. The amps we provide as a choice, we have used over the years and know they will work well in the particular function. Meaning all you have to do is plug in connect power and enjoy. Furthermore if you want to add an amplifier for subs we offer the option to add an Active LOC to your harness for future integration. Check out more below.

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.
