Okay there's LOTS of misinformation going around in this thread.
1. 6-1/2 or even 7" speakers WILL INDEED fit upfront without cutting I know I've done it. and if you want pics, check here...

2. 5.25" speakers ARE the best drop-in-fit solution for a P5 or msp. The reason for this isthat FEW if any ppl installing a 6.5 in the back ever think to trim back the plastic rings that extend back from the doorpanel and it wind sup cutting into your surrounds
3. do NOT try to add "midbass" to the rear doors. this is a silly idea. jsut get a nce set of 6.5 or 7" component supfront, and run them off of an amp. Better yet, forget about the rear speakers alltogether, run stock rears off of the HU if you want sound back there, and concentrate on getting nicer fronts with a decent amp to push them.
4. Putting speakers in your rear doors of an ES is really not at all worth your while. You WILL inded have to pull wires into your doors which is accomplishable, but time consuming, and at that you should run those wires directly up to your deck or amp or whatever, but mostly, jsut stick with the 6x9's they're in a MUCH better location if you'r einto thewhole rear speaker thing anyway. Suming it up, your stock 6x9's UNAMPED will push plenty of sound for you. even with an amplified front stage.
5. 6's in your doors, hell even 5's will HAPPILY play down to 90-80hz or so, and then you can crossover your sub at 80-63hz and depending on your slopse you should have a very nice even transition in sound. where ideally you'll feel like your sub is upfront. YES, indeed I am runnign a 3-way setup upfront, but it's 90% sheer excess. simple 6.5" 2-way components are more than enough.
6. Tweeters SHOULD atleast be tried closer to on-axis with your mids. High-mounted tweeters look and seem to be fancy, but the reality of things isthat this creates separation in sound and makes things jump from low to high as they transition up the audible range. NOW there's certainly applications for high-mounted tweeters, often it's just a matter of getting some sound up high, Stock tweeters are put there because low power and so so speakers can be accentuated acceptably, but definately not at any audiophile level. NOW, in the top SQ cars it's quite common to run a SECONDARY supertweeter playing fairly quietly uphigh to help trick the mind into thinking everything's coming from up on top of your dash. but this involves alot of careful aiming, setup, and often digital time delays.
7. a 6x8/5x7 does NOT offer a substancial surface area improvement over a 6.5 and certianly none over an oversized 6. THe round speaker thing is mostly a matter of uniformity. there's ALOT more cars that a 6.5 will fit into than a 6x8, so the industry makes 6.5's
8. Most 6.5's do not come with 5x7 plates, but most 5.25's do. the reason behind this isthat there will be bolt overlap with a 6-1/2 where having some thickness to the plate is neccessary because your speaker will be mounting outside of the standard opening, and not may cars have verymuch room forward to go. as it is in our cars you need to trim off a ring and be careful.
misc comentary by poser:
DAMn this place is gettin ghetto. PLEASE use the search feature. there's TONS of incredibly worhtwhile information on EVERYTHING you could think of inhere. Suprisingly enough, thisis one of the more educated audio forums on the net, and I hope tokeep it that way.
Pair sof any kind of subs, I find to be jsut silly unless it'sa matter of fitment. a single driver of the next size up will almost always give you equal output with less box size, money spent, and power. ESPECIALLY if it means a difference in stepping up to a nicer singsub than 2 cheap lesser subs.
