RCA Audio Noise Filter for Car Audio/Home Stereo System, Portable and Lightweight

Feature:

- Eliminate Noise: The noise filter can immediately eliminate the hum / low frequency noise / static noise from your car audio system / stereo system / speaker and provides you with clear and clean music.

- Wide application: the ground loop insulator is suitable for amplifiers, stereo receivers, car speakers, car subwoofers, etc. It is widely used in recording studios, meeting rooms, car amplifiers, active subwoofers, players, computers and other devices.

- 40-Pin Harness Adapter with High to Low Impendence Converter.

- Designed for adapting the Audi with BOSE system or other with rear amplified speakers. It can also be regarded as an extension harness cable. 

- It's for Audi A3/A4/TT models with rear speakers have no sound or have static noise after installing aftermarket car stereos.

Note 1: Compatible with aftermarket car head units which use power harness with 40-pin plug.

Note 2: Models with BOSE or Active Rear Sub System; sometimes with BOSE, you get some alternator whine or interference when you change the factory stereo to an after-market one. An after-market unit will always be more powerful than the stock unit so it requests more. The trouble is, the BOSE amplifier is not shielded so it causes humming, interference or engine whine through the speakers. You will require ground loop isolators and an alternator interference suppressor in order to eliminate this whine/noise.
