what to run?

im on a budget and just moved and pawned some stuff off on a brand new 10 1800w boss dual 4 ohm phantom sub, i already have amtx 12 jackhammer in an mtx ported box with a 1000w planet audio amp and i want the best overall sound, for speakers i have sony xplod 6x9 reaer and alpine component 5" in doors with two extra rweeters so my question is should i keep what i got for sub and amp and get equalizer and things to make better sound and tune sound and get better wiring or get a bigget amp and ported box for the boss sub? idk witch would be the best bet

does the CD player have any tuning capabilities ?

yeah but its just the basics that most all of them have it doesnt have all the good ones

then I guess it depends on whether you want sound quality or sound quantity. Would you know how to use or tune an extensivde processor ?

ya im sure i can figure out how to run the processor if not i work witha guy thats good with car audio.
