Randy, looks like Clarion came out with a new model for 2006, the EQS746:
http://www.clarion.com/us/en/products/2006/audio/processors/EQS746/us-en-product-pf_1134643389018.html I have the Clarion EQS744 and it's great:
* boosts voltage to your amps for cleaner, stronger signal
* 7-band EQ
* AUX input for satellite or MP3
* fader knob
* seperate sub amp volume control
* master volume knob
The cheapest I found it when I was shopping was here:

Try to mount it where it can't get wet if possible. Mine is under my dash, set back a little and angled up slightly for viewing. Others have mounted them in the dash or sidewall by the throttle arm, with only the knobs sticking out.
Also, doesn't matter what amp(s) or head unit you're using. It will boost the line level of whatever you're using.
