Kenwood KCA-RC01A Wired Amplifier Remote Level Control

Its Works great, easy to install and small. easy to work with

As described

This served its purpose well! Watch for a good deal on these as the warehouse gets them in on occasion. Had no issues and the cord is very long!

Added to a Kenwood xr901-5 and works as described.

This is absolutely great for songs that you want loud, but you can control the bass from song to song!!

100 well done job

Works like a charm!!!

It should have a mount instead of sticking it to somewhere in the car.

It controls the watts to the subwoofers. This allows you to turn up and down the bass to your preference.I didn't rate 5 stars as it doesn't come with mounting brackets and requires you to drill a hole for the nob itself.This might be of value to you if wanting to make the knob look as though it is apart of the stereo.To clarify further... Most bass knobs come with a bracket and screws to attach the nob somewhere by the driver. This knob doesn't do that. It is set up to have a small hole drilled in your vehicle then the knob unscrews off of the base to allow the base and cord to be concealed somewhere and then the knob screws back to the pin on the l base once the base unit is installed.

I plugged this into my amplifier to my subwoofer and it will turn the bass down but it hardly turns it up. I made sure everything was plugged in correctly (its just one wire) and all it did was make everything quiet even when I turned the knob all the way up. I even had to make my own mounting piece because it didn't come with one, so I wasted all that time making sure everything was right just for it to not work. How is a product this expensive this terrible?!
