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.

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.

Great Product!!

April 1, 2013

The product has a very good price for what it does. It came to me in a very short amount of time. East to install, no issues at all. Has been working ever since.
Again, never look for things like this any other places than Sonicelectronix. Don't waste your time in any other stores.

It worked

February 12, 2013

I installed a Car PC and it was plagued with all kinds of noise due to many ground loop issues. I installed the B25N before all of the amps and now it is totally silent.

The resulting dynamic range is amazing.

It's a simple product, bu it does what it says. A little large, but has some mounting holes, which is nice. Worked perfectly.

Highs or Lows

April 22, 2012

I installed one of these in my car between my head-unit and 15 band trunk EQ to stop engine noise i was having. After installing and turning on my car engine i was the happiest on the block, all my engine noise was gone, my mids and highs lit up my neighbourhood.
Con: My subwoofer was no longer recieving sub frequencies!!! So i was left with no engine noise and no bass.
