Install Bay IBNF50 Noise Filter 50 AMP Each

After months of researching solutions and nearly giving up, THIS cheap and easy to install noise filter completely eliminated the alternator whine in my 2004 mustang. Alternator to input, battery cable to output. Can't believe the solution was this easy.

Installed an aftermarket deck and Alpine 4 ch amplifier for the speakers in my 1985 Toyota pickup. Loud alternator whine from the speakers that I couldn’t seem to fix through multiple ground attempts. Installed this between the battery and the amp and the whine is gone! Very happy. It actually mounted right on the inner fender wall with existing holes.

Easy to hook up. Didn’t work for me though. There’s so many variables that can cause the issue I was trying to fix, therefore I won’t fault the product I purchased. Still have the high pitch whine/squeal that increases with acceleration.

I was lazy. I get spark plug noise. Lazy becuase instead of pulling my dash apart I found the electrical feed and filtered all the trucks electronics . It worked as it supposed to. SIDE NOTE for the altermator whine make sure you filter switched side of your stereo the constant doesnt care

Looks like it's very good quality but it didn't remove the alternator noise like I was hoping. It slightly reduced it but didn't take it away completely like i was hoping.

I installed this product and even added a larger ground wire and for some reason I can't get the whine out of my stereo. I must be doing something wrong. An electronic shop said to install a larger ground,which I did,and I still have the whine. Either I'm doing something wrong or this product did not work for my application.

Mine came with The metal cap not glued correctly. So I can see the inside. And I never put hardware on my car without testing. I'm glad it arrived slighly opened.I didn't tested it at all for the moment. But It need more insulation for pcb connection, reflow the unmelted solder, and check crimping of cables.The connexion of cable: solder unmelted completely, and not completely crimped. Wire are really thick for this price it's a good point.For the pcb itself it seem' well made. between IBNF 50 and IBNF 30 it's the same pcb but wire for the transformer is really thicker on IBNF 50 due to the fact it's made for 50amps.I don't think the brand try too fool you. But before plugging this in do what I said. And instal cable fixation in all possible holes of the pcb.I will made a review for ibnf 30 a

Removed alternator interference that was being picked up by my amplifier.

this work for me to significantly reduce my alternator whine on an aftermarket stereo setup. it was driving me crazy and it finally seems to be sorted.

Didn’t work at all

The unit works as expected. Has nice connectors. I shaved the sides down so I could bolt them straight to my amplifiers. Good guage of wire provided. Well insulated. Flexible, braided wire. I'd certainly purchase them again! I had a loud alternator noise and my electronic aftermarket fans were quite noisy - I purchased two of them and they took all the noise out of the amps.

Seems to have help with the interference noise in my ham radio.

Worked for one day and after that main fuse kept on blowing, when ground was disconnected then fuse did not blow
