what size speakers did you guys put it the front doors and in the back for the ext/crew cab guys??
i just ordered a pair of the alpine spr-17s speakers which are 6.5 inch and the backs are spr-13c which are 5.25
should that get a good sound or should i have gone the the 6.75's up front and the 6.5's in the back??

6.5 in fronts, i didnt do rears. the rears people use 6.5 in aswell.

i have a crew, and went 6.5 in all 4 doors.

sound good?
and what speakers did you put in if i might ask?

I like the sound in all 4 doors but I made a bad choice with the rear doors. All I can say is get GOOD speakers.

OOPS sorry I put infinity Kappa 62.7i in rear and reference 6020cs in front. The Kappas in the rear I headed for the TRASH they sound bad when you turn it up. I really think I am going to put Focals up front and may move the 6020cs to the rear.

Alright so I hear that the 6.5 speakers need a harness to mount them because the whole is too big for them to mount perfectly. Has anyone used a 6 3/4 inch speaker and does it fit without the modded speaker harness?

I want to get a better pair of Blaupunkt speakers from Crutchfield (mostly because I like the convenience they give by giving you pretty much everything you need to install it for free). Otherwise I would go with Audiobahn. But for now I'm going to have the stock HU driving the new speakers until I can get enough to buy a new HU.

My rear door speaker blew and I gather it's time to change them out. I just a bunch of articles that say the speaker harness that comes free from Crutchfield is a POS in some models. Just want to know if anyone here has any experience with them. I'm skeptical about it, I don't need my speakers falling into my door and breaking.

Thanks in advance

how big are the speakers in the rear of an ext cab? is it 6.5" like the front?

Yes
