Rockford Fosgate OEQ1
AUDIO CONTROL EQL seriesII
I have both, brand new trying to decide which to use in new set up.
What would you recommend and why?

 

The OEQ1 is a better EQ in my opinion. It's only issues are that it doesn't have gains in/out and it is limited in the voltage it will take.

I do not like the EQL. I have never installed one that did not introduce noise into the system. Plus I don't find its set band points particularly useful.
