🚗 Vosarea Car Amplifier Noise Filter: 4 Channel RCA Ground Loop Isolator for Clear Audio, Line Noise Filter Eliminator 50W (Blue) Review

When you need to run all your audio cables down one side of your car. It is necessary! This removed any noise from all 4 channels.

I read a lot of reviews about this product, I tried it and it worked great. New subwoofers with deck amps removed all noise, no more hiss, no more hum! Great product, thanks!

Totally useless for my EMI, hiss, alternator whine, static electricity. Didn't hear any difference and no built in amp for my mids and highs. That's why I chose the PAC SNI-1 Noise Isolator. Hope this works. Also 1 more thing to add, never heard of Vosarea but took a risk because it was 4 channels. Had to buy 2 PAC units but it was cheaper than this POS.

Removes most of the noise, but not all, which allowed the amp to increase volume significantly. I just want all the hiss to go away.

The device stops static electricity, but does not allow lower frequencies, e.g. B. low frequencies by. When installed, the 12-inch basic loudspeakers lost 90 percent of their bass through the amplifier. To return. Useless.

I read many reviews about this product, I tried it and it works great. I have a 98 Mustang GT. and i installed a sound system, the new deck amp subwoofers removed all noise, no more hiss, no more hum, great product, thanks

This completely filtered Meek Mills' voice out of the song, all that played was just the beat and some static which it didn't filter out. If your goal is to listen to a bunch of instrumentals + whatever noise you want to filter out, buy this. If you want to filter out unwanted noise from your speakers I wouldn't recommend buying it.
