Review: Works as described - I don’t know how it works, but it does. I run a mini pre-amp thru my boat stereo to use with a CB style mic as an inexpensive PA system. (Guided sightseeing charter boat). New boat had a ton of line noise when the engine was running. So much, the PA was not usable. I ran the 12v supply for the stereo and pre-amp thru this isolator, and it greatly reduced the noise. There is still some noise, but it went from un-usable to useable. To be fair to the remaining line noise, I have to crank the radio volume to 33-35 so my guests can hear me. That’s pretty high, and I don’t fault this product for not removing 100% at the highest volume. Oh, like others have said, the wire insulation is ridiculously thick, but the wires are maybe 14 gauge, and appear tinned. The thick insulation only makes butt connectors really tight.
Review: Best $15 I’ve spent in many years💪💪‼️ - I was getting ridiculous engine noise and was at the point of purchasing a new deck but thought I would give this device a try before that decision. The install took me all of 15 minutes and the sound quality improved 100%. By far the best $15 I’ve spent in a very long time‼️💪💪

### ⭐ Eliminated alternator whine 100%
*by B***. on August 14, 2025*

Updated Review 08/27/25: After it was installed in the car two to three weeks, it failed and would blow the car radio fuse instantly. I checked all wiring connections to make sure nothing had come loose. Once I removed this device, the fuse stopped blowing. I recommend not purchasing this item. My original update is below. I installed this in my 1999 Plymouth Prowler after replacing the factory radio with an aftermarket unit. Immediately after the radio swap, I noticed a distinct buzzing sound from the speakers that varied with the engine's RPMs, a classic sign of alternator whine. I was frustrated and worried I'd have to live with the noise, but then I installed this product. The difference was night and day. The alternator buzz completely vanished, leaving me with clear, clean audio. This device was easy to install and it completely solved my problem. Highly recommend it to anyone dealing with similar audio issues after a stereo upgrade."
