Ok, Im running a stock HU with some 4x6s and 2 6x9s... I will be using a 300w amp and a 200w rms 10" sub...

I am looking for an inline sum/amp controller so if a song with alot of bass comes on(dont want a shit sounding stereo) I can turn down just the sub. I dont need an EQ with all the controls and what not...

I really just need something that I can control amp gain with so as I said I can have adjustability from my seat(amp is behind passenger seat with no way to reach it...

thanks
-Mike
