kenwood = head unit
rockford fosgate bd 1501 = amp
sony xplod, rockford fosgate e2, alpine type r12's = subs
boston accoustic = 6x9's
boston accoustic = 6 1/4 door speakers
if you want tweeters boston accoustics or pioneer r the best but u truley don't need them.
also if you want you can replace the i believe its 2 inch speakers in the dash by the windshield but its not needed either
and try the new fosgate subs...they r badasss i just bought 2 new 10's and they fuckin pound with that bd 1501 amp and its some clear ass sound compared to thier older models
and with all the other boston accoustic components ( 6x9's and 6 1/4's)that r amplified i get killer sound out of my car.
