Installed on a Rockford Fosgate 5-channel amp,with JBL in the doors, Pioneer 12 in the trunk, Clarion highs in the back dash.Really brightened everything up,and brought the staging up to eye level.
Pros: one pair of RCA in one pair of RCA out

I had great individual components- JBL 6 1/2" components in front doors, sound deadening, Boston GTA 1005 5 channel amp, JL sub, but overall sound quality was lacking. I knew the problem was my factory head unit but didn't want to spend hundreds of dollars on connectors, bus units, etc., etc. and still lose my paid-for satellite radio subscription. The LC2i line-out converter worked wonders for the bass, but when I had the EQL installed...WOW. The amazing sound put a smile on every face at the shop. I had it professionally done so they used an O-scope and did the pink noise test, etc. and you would not believe how flat the curve looks. My system sounds fantastic and this EQ was the final piece of the puzzle. (Well I do need to upgrade to a JL 13W3, but that is in the future)
Pros: Exceptional clarity and ruler flat response curves from a factory head unit. World class customer service from Audio Control (and Crutchfield)
Cons: Added a tiny hum when turning off, but most won't even notice- I am a perfectionist.
