Preamp question

SHIFT3

So I have a Sundown sub hooked up with a LOC running into my Power Acoustik BAMF5500

I have a Massive preamp eq laying around from my previous car

So I tried to wire up the preamp eq so I can get some control over the quality of bass in getting but when I hook it up there seems to be no signal anymore

I know the preamp works because I hooked it up with an aux to play straight to my sub without a problem

But when I run the signal coming from the car it just outputs nothing

Anybody have any idea why?

Im guessing its an input voltage issue. It almost makes no sense to try to hookup a preamp eq to control strictly the few octaves your subwoofer is using. Your amp should be all the control you need.
How many bands on the pre-amp relate to your subs freq. range? the ends will probably not justify the means in this case..... Just another source for issues to arise, noise, clipping, distortion, ect, ect.
