If any of you are experienced with setting up a dual mono, 30 band eq, your expertise would be appreciated. please describe where you start and what your techniques involve. For reference i have the premier p9 deck and processor. i also have access to an audio control rta. thanks in advance

Equalization is definately person specific.. Except for RTA equalization. To equalize to a flat line (generally people only use one side of their stereo when doing RTA) you simply tune until the line is flat on your AC RTA, usingthe microphone in a head-mount position.. Tuning from outside the car is a good thing.
Equalization to ear is simply a matter of preference.. A good idea is to take a few listens to cars that have done well at several competitions, and also try to listen to non-equalized GOOD quality headphones. Do not listen to home stereo's, and bear in mind the bass will have different effects in a car.. The RTA and SQ tune should be the only ones you tune for competition.. Tune other presets to a sound that you enjoy.

I concur (as usual) with Jesse. I will add this: Try not to boost ANY frequency with an EQ, instead, use the eq to CUT bands that are high.
Here's why- let's say you have a serious dip between 1-3K of 9dB in each band.
You boost those freq's to normalize that band.
Now your amp is being asked to put out 27dB (9dB per band X 3 bands = 27dB) more SPL in those 3 bands.
27dB is equal to >256:1 vs. the non eq bands, or 256 times the power to those specific bands.
A 100watt amp would be asked to put out well over it's maximum wattage to reproduce those frequencies without distorting....
Make sense???
Now, if you were to EQ the adjacent bands DOWN, your amplifier would be asked to put out LESS power, increasing dynamic headroom, reducing distortion, and making for a better sounding system.
If you find that cutting bands means less output, you can always GAIN UP THE AMPS to compensate, unless that induces noise in the system, but it shouldn't unless your system is prone to noise in the first place, which means you may want to re-touch electrical connections, especially grounds.
