Well, I got them installed last night and they sound really different than my CDT CL-62's. The clarity of these speakers (minus the hissing I have) in incredible. I moved the tweets from firing off the windshield to firing accross the dash, mounted them on the A-piller. The mid-bass is decent, more than my CDT's, but I still need to do some tuning here and there. My front stage seemed to improve a little. There is more left-to-right and it has risen a good 8 inches to a foot. These speakers are more in-your-face than my previous CDT's, which were pretty laid back. So far I really like them, but only time will tell.
On a side note, is there a good way to tell my crossover is set to 80hz? I had my amp set at 80hz going by the marks on the dials, but it seemed to let alot of low notes reach the components, so I don't know if I trust it or not. Would a test tone work?
