Calrad - 95-879 Alternator noise / whine filter.

Alternator whine in your car stereo can be an elusive problem. As the RPMs of your vehicle rise, the volume of the alternator whine can increase as well. Identify the underlying cause of the whine to silence it for good. There are several possible causes of alternator whine and troubleshooting is the best way to isolate it. If proper grounding and wire placement does not eliminate the noise, a filter may be the ultimate resolution.

Automobiles equipped with alternators can reduce annoying noise on amateur or CB gear with use of this easy-to-install noise filter.

Maximum current 25A.
