right lads, what speakers can/should i replace in my MR2 turbo?

the front speakers in the doors seem.

.crap and the ones by the seat belts are ok-ish but could be better.

think there's small tweeters somewhere too, by the mirrors are they? don't care to much about them anyway.

basically would like a small set up, just want to know what i need.

would like 4 speakers replaced as mentioned so any recomends for them? and maybe 2 10" subs behind the seats? again recomends for subs

+ boxes to use and lastly it'll need an amp again recomends?

i like my sony head unit so wanna keep that, any ideas on what the speakers

+ wood for the boxes will cost? what type of wood is best? i'm considering giving it a go myself when i have the dough again.

not wanting a show stopper system, just something that's good and has decent bass hence the 2 10" subs
