Does the job and I have no complaints that worked out very well I love it

This device some people call a bass knob which is okay because I do too. It's actually a line level controller which works similar to a base knob except you can add this to any aftermarket amplifier utilizing your RCAs coming from the back of your head unit. This controller has the line level input from the back of your stereo you plug that into the input then it has RCA left and right output you plug an RCA cable to the output side and the other side of those cables you plug into your amplifier. All it does is decreases or increases the frequency of output going to your amplifier kind of like a middleman that way if you have songs that have really strong bass You can turn the controller or knob down and vice versa similar to a bass knob except like I said earlier you can use it on any amplifier. I have an amplifier that has an actual bass knob and it started crackling because the knob was going bad after 3 years so I decided to purchase this with great reviews and great videos. I found this to be the best choice. I'll make a long story short. When I turn off my truck it is completely quiet as far as my sound system but when I turn it on or crank it up after a few seconds my head unit comes on and there is a strange thump in my subwoofer. When I had the bass knob hooked up even with the level all the way down it's still thumped. When using this line output controller/bass knob I turn it all the way down when I leave my truck and when I crank it back up I wait for the head unit to power up and then I have no thump whatsoever from my sub so this thing can actually cut the signal down completely instead of partially so there is very good control utilizing this knob controller. I would definitely recommend to anyone with any kind of aftermarket amplifier controlling a subwoofer to use one of these. They are relatively inexpensive and a good piece of equipment to have in your sound system.
