thanks for all the usefull information. it IS a standard cab, but you mentioned speakers behind the seat? there are just the speakers in the dash which is why i had came up with the idea of putting some in the doors. (seems to be pretty common) which i was thinking 6x9's so i wasnt sure if id need an amp for two of those added to my system. i didnt think the dash speakers would be much even if i upgraded them (i could be very wrong seeing as it is a small truck)
i have a new head unit i got from my brother which is a fairly new pioneer that he got a few months ago.

is there like a usual amount of speakers newer head units can power without an amp? usually if you want a sub you need and amp right? (later project)
for right now i just want to get a pretty descent sound quality. i listen to pretty much everything (rock, rap, country) and i like it lound and clear. which i was pretty certain two 4x6's from 1985 wouldnt be able to provide me with.

thanks for your help,
ryan
