Just bought new reg. cab sub box
all 4 speakers are 5x7. you can fit a few different sizes in there tho. 5.25s, 6 1/2s.. 6x8s (im pretty sure anyway).
right now i have 6 1/2 components in my doors, with the tweeters flush mounted up on the dash near the wind shield. i have no rear speakers just becuase the front are simply loud enough, plus my sub box covers where they'd mount!
a decent speaker isnt too hard to find if you're looking to get better than stock. memphis makes good speakers, eclipse, mb quart.. theyre all pretty good.
if you're willing to spend some money to get great sound, look into mb quart or morel speakers. i had a set of phoenix gold Ti5 Elites, they were 300 rms, 600 max.. and actually handled those numbers, they didnt bull **** thier numbers like most companies do. my cross over for them was having problems, (factory, not becuase of me!), so i swapped them out, the put a little more money down, for a set of Morel Hybrid Ovation 6s, its their top of the line speaker. they're 6 1/2 components, and they're great. i love everything about them. if you are willing to spend the money, id recommend a set. ill be getting a second set soon! gotta get another amp for them first tho!
