i want to get my wife some better speakers for xmas. for supposedly having the 'premium' system it sure does suck. my question is to someone who has upgraded audio in this car. the factory specs say '350w, 7 speakers with 8" sub. i was trying to put together a package at crutchfield with at least new component system for front, and a new 8" sub for the rear deck but the site does not list an 8 sub for fitting the rr, but instead lists 5-and-a-quarters. which is right? is the 5-and-a-quarters for the regular civic and the si has the sub maybe? i dunno. i cant look at it right now as she took the car to work today. any advice on what to get or how?
