ok, i have a 90' pontiac grand prix, and ive chosen the stuff i think would be good for it, and i also need help with amps... ok, so im prety sure i want the Alpine iDA-X100 deck, and then for fronts i want the alpine Type-R SPR-17S 6.5'' speakers, which comes with tweets, speakers, and crossovers, and then from a friend i will probably buy 2 brand new audiobahn 12'' subs, and a 1200 watt pyramid amp for them
so now i need help, does this setup make sense?(im new to car audio) and what speakers should i use for backs??? could i just buy 2 sets of the alpine SPR-17S?? would the work? or what? and also, with this setup, what amps should i get? in order to make it work the best, well any help is appreciated, thanks 
your deck and fronts are nice but your subs are not. if you heard them and you like them then go for it but audiobahn isnt a respectable brand for subwoofers. try the pioneer premier championship pro series (in the link below) they are a good brand and reliable and hit hard as hell. with those subs you would want to go with about a 2000-2500 watt amp. Hifonics is a very good brand for amps and its affordable and reliable. for the rear speakers i would go with some alpine 6x9s then you would really be BALLLLLLLIN!!!!!! For car audio its best to go for quality and reliability and not the cheapest price because you get wat you pay for. look at the links below of the pioneer subs and any of the two amps would go perfect with them i suggest the 2600 watt. hope this helps. good luck
