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.
