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.

I was picking up RF noise from a power supply I added the filter and it changed nothing.

Opened to see circuit and quality. Believe it will work fine for AM broadcast and HF frequencies. It uses conventional Pi (C-L-C) design. I won't use it in my truck or car, since the case is 0 020" (0.5mm) steel and will soon rust. Base mounting plate is BARE (unpainted)! Furthermore the gap between base plate and case isn't sealed. Needs, at a minimum, caulk to keep water out. Buy if you don't mind painting and sealing it .

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 added this to my kids aftermarket audio system upgrade. He was getting a lot of alternator feedback. After installation there was a decrease in feedback but it’s still there. So not 100% effective as for installation pretty straightforward just connect to the positive leads to the head unit and ground the isolator. I went a step further and soldered all my connections. So for effectiveness I give it 35% in noise reduction.

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.

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.
