Our DIY harnesses are just that ! They were requested by those that want to build their own harness or repair someone else's handy work. The DIY style is an inexpensive way to better your install craft and keep that vehicle resale value up.  

If its a speaker in your car our harness will provide the high level signal on one end and let you build the rest from there. 



NOT ALL VEHICLES HAVE THE FACTORY WIRE SIZE TO HANDLE A LOOPBACK STYLE INSTALLATION! IF WE DONT OFFER A HARNESS IN THE LOOPBACK STYLE FOR A VEHICLE PLEASE USE THAT STYLE WITH CAUTION AND CHECK YOUR FACTORY WIRE SIZE! A simple solution is not always the safest!

THIS HARNESS DOES NOT WORK with factory amplifier equipped vehicles.


Thank you 😁

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.
