Would not recommend for a MTX amp.
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 .

Perfect
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.

Convenient Control
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.

Do Not Buy - You'll Waste your money!
I should've come here first. Wastes money. Doesn't work at all. The 6 pin cable doesn't work and won't fit. cheaply made as well for $18.... disappointed. Would've given it 0 starts if able, but I guess the install was easy... so if you want a prop knob, you go the right product.
