Noise Filter Specifications

Noise Filter Type
This designates the type of noise filter listed.

Ground Loop Isolators are connected in-line with the RCA interconnects or other audio cables.

Power Line noise filters connect to the power line of the receiver and help reduce noise from the source.

Pop Eliminator noise filters are designed to remove the "pop" that occasionally happens in some systems when the vehicle is turned on.

Ground Loop Isolator
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

December 6, 2009

I was very skeptical of buying a ground loop isolator that plugs into rca ports considering all the good ones you have to solder on. My friends and i took apart the whole interior of the car, used a dremel to ensure good ground and no paint on contact. Did everything we could and there was still a large alternator whine. When all else failed, i thought buying 2 of these for 15 bucks total could not hurt, especially with free shipping. Came to me the next day, plugged it in, and it works like a charm. Thank you Sonic Electronix!
