I have an active car subwoofer in the boot/trunk of my car.

It is connected to a Philips CarStudio CE152 car stereo up front.

I have included an image of the subwoofer controls to this post.

Is there a unit I can buy, that will help me control the subwoofer from the front of the car?

 

you can get an in line fader for the RCA's
