I'm building a 99 2dr Tahoe with 4 DC level 6 18's with 20k watts going to them, and I need some suggestions on the mids and highs. I have an Eclipse 7200 mkII head unit and an Audision bit one laying around that I will be using. I lalso have a DD C2 and an Alpine pdx 150.4 that are not being used that i can use or I might just buy new amps. I need a front stage that will keep up with the bass and not sound horrible. Thanks
