glad to meet you young man. i am simpleton and i drive a '97 GSX that's been
converted to a sixbolt 1G  4G63 motor. there is a lot that can be learned
here but allow me to also direct you to theses places:
www.vfaq.com
www.dsmtalk.com
www.dsmtuners.com
www.dsmtrader.com
www.roadraceengineering.com
www.buschurracing.com

that should get you going. from there you can follow links to get to the
other DSM sites.
there isn't much emphasis on audio, mostly diy repairs and upgrades for
street and strip.
if i had not busted my crank in half, i'd be installing my system now. i
have an alpine head unit and eq with an old skool ppi a600 amp powering
image dynamics horns and boston pro 6.4 mid-bass. there's a single 12" image
dynamics sub going in the back fed by an antique punch 150.....classic front
stage plus sub. i have been out of the audio thing for some time but was one
of the original autosound 2000 subscribers when richard and dave started up.
good luck and let me say i'm glad there is someone to direct my audio
questions to.
