Universal Bass Control Knob, 3.5m/11.48ft Bass Volume Knob with Extension Cable for Car Amplifier

This is a quality bass control knob. I give this item 5 stars, it was super easy to install and dialed the bass in perfectly in our k5 Blazer show vehicle. I highly recommend it.

It says it's Universal, but it didn't work for me. Was very excited thinking it was going to work for me but it didn't. Definitely do your research and see if universal remotes will work with your subwoofer.

Its exactly what I was needing. Worked perfect for my boss amp. Recommended

Great product and price point. Universal should work on most amps

It is a 4 pin but the size of a 6 pin. Did not fit amp had to send back. Even tried my actual 4 pin in the back of it. Didn’t work. Good solid product, wish it worked. Went with the Skar with voltage bass knob powered by rca and wires.

Works great

I purchased this and had some health issues come up and few months later was able to install it and it did not work tried it on 2 different amps and did not work at all so waste of money is not good information or whatever but 2 amps and didn't even light up junk to me

it’s all good i love it
