yeah, if you can turn down everything and you still have the hissing then you probably have a poor ground or your equipment is just noisy.  where did you ground the EQ? did you use the factory ground from the radio or did you make a new ground?

You guys will never guess what my money is on.

my EQ's and headunit's ground wire is connected to my car's wire harness (black wire/-12 volt wire). i cant find a good solid ground for both. you follow me? is this why its making that hissing noise? thanks.

Probably

so i should find a ground (chassis) for both, eq and the headunit?

a god spot to ground might not be very obvious. you might need to run a wire down to the metal under the dash but a good ground that is a bit long is always better than a short bad ground. and try to use a reasonably thick wire

Grounding all components to the same location will sometimes help with noises like yours.  You may want to ground the radio and eq to the chassis of the car somewhere under the dash.  Then take a 10 Gauge wire also connected to that same point, then run it to the where your amps are grounded, and connect it to there too.  The above will probably not help you, but bypassing the eq will at least keep us from chasing our tail. 

cool. i should of thought of that, grounding some where under the dash. no i need to find a long ground wire. "Then take a 10 Gauge wire also connected to that same point, then run it to the where your amps are grounded, and connect it to there too" is this necessary?
