1--he has a point.....

2---run what you want as far as brand name....
this is what i did i got a 90 accord i run a sony head unit 2 yrs old have keenwood 6x9's and 6 1/2's with kicker nd 13 and nd 25 tweeter's and 2 10 inch vr comp's for amp's i run a punch 2002 for subs and a lighting audio
250 x4 all run through a sony passive eq you can hear me for blocks if i want it to be heard and sounds good with all types of music but best of all it is crisp and clean so no matter what you run i would recomend an eq.....
just my 2 cents
