Well, I got some JBL's for the front, and some Fusion's for the rear and fitted them. Sounded fine, but now a week on from the install it's all gone tits up as it were....
if your after loud, then you ain't really gonna get much frequency range from the 3.5 and 4" speakers - your better off getting a sub (active if you want to save on space and effort) and then amping up the four corners. blows your budget though i've fitted a vibe sub and HU and was going to upgrade from the standard speakers until i reaslied that they were fine when you don't try and push all the freq's through them, plenty loud enough from the HU' 50w output and still have good clarity whilst listening to D&B etc.
