Im kind of in the same boat, im either going with the Mach 5 mids and a matching tweeter and going full active, or going with some Rockford Power 6.5 comps.
I have the 6.5 Rockford Power 2 ways in my car now, and they have good midbass, so the comps should be even better. I wish I could go with the Rainbows, but funds wont allow it right now. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
