Universal Bass Control Knob, Bass Volume Knob with Extension Cable for Car Amplifier

Terrible. Didn't work.

Bought for my MTX amp . All plugs work but the bass knob was like all or nothing . Tried turning gains down on amp and still didn’t work very well .

The universal bass control knob has been a really useful addition to my car audio setup. It gives me quick and easy control over the bass level without having to constantly adjust settings on my amplifier or head unit. Installation was straightforward, especially for someone familiar with basic car audio wiring. Once connected, it worked immediately without any extra configuration. I like that it allows on-the-fly adjustments, which is especially helpful when switching between different types of music or passengers with different preferences. The knob itself feels solid and well-made. It has a smooth turning motion and gives just enough resistance so it doesn’t feel cheap or overly loose. The design is compact, so it doesn’t take up much space on the dashboard or center console. What I appreciate most is the convenience. Being able to quickly dial the bass up or down while driving makes the overall listening experience much more enjoyable and customizable. It really helps fine-tune the sound depending on the song or road conditions. One thing to note is that proper setup is important—if it’s not wired correctly with a compatible amplifier, it may not function as expected. But once installed properly, it works reliably. The only minor downside is that the indicator markings on the knob could be a little more visible in low light, but that’s a small issue overall. Overall, this bass control knob is a simple but effective upgrade for any car audio system. It adds convenience, better control, and a more personalized listening experience.
