UPDATE:
Well im still looking and aint bought nothing so far. My parents have giving me some extra money, so im looking at about maybe 1000. Ive decided to get a sub and amp, as my dad strangely enough convinced me to buy one, but not yet. And ive decided to put some 6x9's in my cars rear 1/4 panels.. Atm with my extra budget im looking at:
1 x Pionner HU (either 3550MP, 5550MP or 7550MP)
2 x Pioneer 4" (either TS-E1075 or TS-G1047)
2 x 6x9's (prob Pioneer, not sure which model)
And eventually:
1 x Pioneer Sub
1 x Pioneer 12" or 15" Sub.
One thing i need to know is what of the above mentioned HU's can control a stacker. Ive have about 3 x 6 CD stackers, all of which are not being used. I ripped from my dads old work, and i was hoping to use them. Most stores say that all of the models can control a CD stacker, but on pioneer's website it is not all to clear if they can or cannot. So can anyone tell me if they can.
And i still need help on deciding which speakers to go for and stuff, so keep the suggestions coming.
