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

Works like it should, the light doesn’t turn on but it’s nothing to be bothered by. This works great with my Hifonics amp.

Doesn't even work. Light doesn't come on and the nob does nothing. Plugged in right and everything. Just trash

This was well needed and it does the job. It was very easy to hookup and I haven’t had any problems out of it so far. I would recommend this.

I purchased this to have a quick means to control the bass from my Subs ect. Before if I wanted to adjust the bass I would have to manually adjust the knobs on the amp itself physically and would have to climb in the back of the car/trunk to do so. Not a problem every now and then but a great example of this would be when I’m listening to the radio sometimes the stations can be very “bass” heavy and this is great for “on the fly” adjustments ect. Like being able to turn down the bass all the way and actually listen to the radio on a high volume without fear of blowing up my speakers ect. Or when having a conversation with people in the car it’s so convenient to turn everything down and able to enjoy music on low volume with little to no bass. Now on the other hand it’s awesome to be able to just turn up the sound and bass all the way and shake the road up and down ect. The cable they give with it is super long as well I had no issues running the cable from my trunk into the cabin of my car and the cable had a lot of slack too. I don’t hide it inside the car panels or anything but it’s a option if you want to do ect.

This is supposed to be universal but does not work with my sundown Amp If they want to fix the review, they will send me a new one that works with my sundown amp

Works good I could never get the power light to turn on and the wiring didn't work with my amp so I had to cut and splice the wires from my amp to the new knob it works how it should tho

Very fast delivery, good quality. Works amazing. Now you can hear me driving down the block.

Got this for my new subs and works fine but light doesn’t come on..
