Hey guys, my buddy's got a 1986 300ZX and he wants to upgrade the sound system, and I don't no ne thing about sound systems.. he wants at least two subs and 4 speakers... ne suggestions would be helpfull, and thanks!

my suggestion is dont get subs, 2 components in front and 2 coaxials in back

so what are the biggest speakers you could fit in the back ?

Lol, I have no clue, I'll call up my buddy and see what's goin on, thanks for the reply :)

6.5".. if you're dropping cash on a decent system, i'd get at least one sub.. when it comes to brands, there's sooo many to choose from... but some of the more popular ones are alpine, mb quart, jbl, kicker.... just depends on what sorta money he wants to spend. when it comes to the subs, it also depends on what he wants... quality or that window shattering ridiculous bass... too lazy to type more..

ALPINE is good. i installed ALPINE sound system. makes very clear sound, and strong.
