What headunit to run with my 6xs ?

[SQllover]

I'm running 4 amplifiers. Is there a headunit I can use to tune the 6xs to the right frequencies for my range of speakers or do I need to get the eqs to go along with it ? I need 6 channels, any sugfgestions would be great.

600 dollar budget for cd player. Or if I need the Eqs 600 for both that and the heaunit. I want to have the sub cut out t 60 hertz and have the cdt m6s come in at 60, midrange come in at 650, tweets 3500.
