Helix Cap 33 "Baby Cap" for Car Audio

If you are having problems with noise from your car hi-fi, specifically irritating alternator whines that comes and goes or permanently haunts your music enjoyment, I may have a remedy for you.

Causes of alternator whines or locally termed "aeroplane noise" are bad wiring (running signal cables and wire cables together), a weak battery or charging sytem, bad grounding or ground loops and in many cases cheap amplifiers that are prone to a high noise floor.

If you are haunted with alternator whine and additional grounding does not fix it then you might want to consider this gadget. Unlike the suppressors you see being used by low end installers, this really works without actually limiting the current flow or in layman's term supressing the power.

The Cap 33 works like a small capacitor and is only rated at 33,000 (μF) microfarad. You basically connect it between your car's battery and it's alternator. More details in the Helix website - Audiotec Fischer or contact Autocraft Electronics (M) S/B @ 603-80709231
