Collection: OEM Loopback Harness Style

The OEM LoopBack harness was the invention that put us on the fast track to developing the Elite system. When we designed the oem we new it had to be more then just signal and return. It would provide power and TRULY SIMPLIFY how multi channel amplifiers where installed. Our mix and match of materials allowed us to offer everything you need to fully integrate into your factory system using the factory wires. Twisted pair signal and return mean no out side EMF interference no more expensive RCA of speaker wire. Our Cut resistant PET loom protects against sharp metals and plastics that you come across when pulling the harness into place. We use high end Water tight shrink tube and 300= Volt rated OFC USA copper Wire. 

We are the original creators of the OEM Loopback harness and want to warn customers against company that copy our product designs BUT use cheap wire (speed wire .75 a foot not $3.00) and connection methods or use sign bored over fire resistant ABS and charge the same as we do. Please watch who you buy from. Stay safe stay loud.

What is Shock-Wire ?

Well its as close to perfection, and true audiophile quality, that you can get in an RCA cable. Our specked wire design means the same accuracy and quality in every RCA we manufacture. Its about shoiwing what true quality & performance looks & sounds like. Our Shock-Wire brand is designed & developed by the owner who has 8+ years as a comunications technician. "Understanding how signal reacts in its different enviroments is a big factor in our RCA design. We use methods that we know will deliver in the worst of places". So why spend more to get less?

What is ANC ?

Active-noise-control(ANC) technology takes advantage of the vehicle's audio system to diminish unwanted noise generated by the engine. To reduce that noise, engineers use active acoustic control or ANC to generate noise-cancellation signals, which are played on loudspeakers in the car's cabin. If this signal is processed by the aftermarket amp you will hear rumbling when engine is revving up or your subwoofers are picked up by the ANC microphones. In this situation the ANC must be bypassed.
