LPL for Amp not working (bass knob)

[Grip72]

Ok i went and bought a LPL (low pressure level...it hink) knob today which i can use to controlt he gain on my amp without having to touch my amp. Its just a knob that i can mount by my cd player for easier and more convinent controls. Anyways, i hooked the focker up and it won't work...why is that?

ive herd of alot of people having problems with those things...youd be better off buying a decent EQ with a gain controll or sub level controll on it

like a sort of "in-dash" eq with the little bar things u getta slid and shit and kobs and stuff?
