My truck has 6x9s in the doors. It came with factory 6x9s. I can send you one if you'd like.
The Mountaineer comes with 5x7s (also referred to as 6x8s, although the two sizes are equal/interchangeable in the car audio industry). Maybe a 6x9 would fit without much effort. But it didn't come with 6x9s from the factory.
As far as my plan goes, I'm surprised that you would think it would sound anything other than amazing. Quite frankly, stock locations are not designed with sound quality in mind.
And you think that mounting a bunch of 3-way and/or 4-way speakers in the B-pillar is better for sound quality? That's incorrect. For better SQ, you don't want speakers next to or behind your head like that. You're much better off having a nice set of components or simple 2-way coaxials in the factory locations. If you want to move stuff around, mount them even further forward in the kick panels. Maybe try the tweeters up in the A-pillars, although as a guy that's more focused on SQ than most people, I prefer to keep my tweets close to my mids, run good gear, and adjust the eq, phase, and time alignment as needed to achieve proper imaging. If you don't carry passengers often, you could even get rid of any and all other speakers (except for your sub stage). Most SQ purists don't run any rear fill at all. Personally, I like rear fill; I have a rear seat set up for entertainment of passengers, and I also play movies and concert DVDs in 5.1, so I do run rear speakers.
Based on the fact that you have a 7cu/ft box in your truck, I'd assume you go for SPL and not sound quality.
That would be an incorrect assumption. I think most car audio guys in the know would actually look at my system list and realize that it's much more tailored to SQ than SPL. Do you know much about the components I run or the processing capabilities of the 701? Are you familiar with what JL HD amps were created and intended for? Don't get me wrong - it's LOUD when I want it to be, but with the time, money, and energy I've invested in it, if I wanted it to be an SPL system, I would have gone a completely different direction, and it would have a lot more than two 15s in it. That said, it was not designed, built, or ever intended to be a competition SQ vehicle. It's just something I built for my own enjoyment to accurately reproduce different formats and get loud while sounding very, very clean and clear, with good staging and imaging. Those who know SQ understand that staging and imaging are the most difficult aspects of car audio to get just right, and you certainly can't get it done with speakers in your B-pillars.
I've been installing custom stereos for about 15 years now, I've built boxes to fit in places that no box could fit. The way I'm doing it works just fine. I have customers that would certainly agree.
I was just trying to help. To be honest, I figured you were just some novice getting into the car audio scene, with grand (but misguided) plans. A lot of people are never shown the ins and outs of putting together a great sounding system. I've been a car audio fanatic for a long time, so I like to help guide people down the right track when I can. If you believe that you know what you're doing, then you're not going to listen to my advice anyway. At the end of the day, if it sounds good to you and your customers, then maybe that's all that matters, anyway. I don't doubt it, either, because a lot of people don't have a clue about good sound reproduction in an automobile.
Good luck with your build.
