I have heard this exact set-up. Nothing special IMO. Atleast not compared to my Infinity's. The only way we could make them sound loud enough to be suffiecient is to turn up the Hertz, but then the bass gets really hollow and voice starts travelling through the subs.

I like bass to be as clear and clean as possible. You'll never really get that in a ported enclosure in a car, only in a house due to the cab size. I have built, heard and used every enclosure known to man. Nothing beats a properly built sealed enclosure with a quality sub. Nothing. Most audiophiles will use nothing but sealed bass encosures for a quality sound. Unless you like that drawn out bass that over shadows the musical highs, then a ported or even a bandpass box is for you.

 

The hardest hitting vehicle I ever sat in was a reg cab S-10 with 3 JL 10w6's. And the bass was pretty decent from what I can recall, but that was over 10 yrs ago...back in my H.S. days.

So you don't need big speakers for big bass, nor a big cab. This thing hit so hard, you could hear him drive by the school during the day (yeah, he was either a druggie or dropout) and the school was 100 yds off the road.

 

you can use 2" square toobing to raise your seats and thus provide more room if you wanted to spend the money on a custom box. on top of that you can cut one of two things from the storage tray (1. you can cut the lip off of the top or the tray. (2. you can cut the whole forward part of the tray with out worrying about loosing strength since the truck is obviously not a unibody except you will loose your cup holders. they are just spot welded in so a drill and a carpenters knife will do the trick. also put some sound dedning material in place of your carpet where you want the box. it will add space to make the box bigger as well as help with the accoustic resinance

 

http://www.extremeaudio.org/van_gallery.php This is the loudest Ive ever heard Its my cousin Mike Bartells, out of Mechanicsville, VA. He was "recently" featured on Mythbusters, theres a link somewhere on the website. He's currently the second loudest in the world.

Its funny this thread popped up today, I was just told by my wife that her and my mom are going halves on sending me up to Mikes place and getting him to set me up for my birthday (feb). I can't wait to see what he can pull off with the limited space we have in these trucks. Im thinking of going one 12", allowing the biggest box possible with most air travel, versus 2 10's. We'll see

 

I dont thing you have any idea of what you are talking about at all. Sealed has nothing to do with a car the produce tighter bass and have a lower SPL rating and require more power to hit the same lows as a Ported or bandpass encloser. I gaurantee I had more bass in my mustang with 2 sealed 12's then you had in your SUV with ported. As far as cleaner goes a ported box is WORSE than a sealed it will hit the lows easier because it has less resistance for excursion if you want hard hitting lows go for a bandpass but good luck getting that in without removing the seat as it requires a lot of space. If you want lows out of your 12's you could look into giving them more power since they are in a sealed box which requires more power you will be able to get closer to reproducing the SPL's just dont over power them. Also an SUV or truck the sub is in the same air space as you are same as hatch back cars were cars that have trunks it has the back seat which seperates the air space that is also another reason it seems that the sub hits harder i would learn a little more about subs first

 

Just instaled 2 10" kicker CVR's in a probox. The sound great. Hits hard

 

I just redone my whole system with Diamond Audio Hex and Kicker. I am running 2 Kicker Comp vr 12's and KICKER ZX750.1 and have no problems with bass out of my box under the rear seats. So whom ever thinks 12's are not the way to go come over for a listen you will have a different oulook on it. Nothing against 10's or single sub but buy good stuff and bass won't be a problem whatever you get.

 

I'm going to do diamond audio all around (except jl 10w7) as well. Did you just replace factory or did you make it custom? How do you like the high's on the diamond. i know that the beat boston acustic and mb quarts in every contest especially price.

 

I replaced everything in vehicle including all new wire through the doors. I just finished a few weeks ago. Still tweaking amps but the Hex sound awesome. Clear and loud but it took some time getting them to sound just right. The highs were so high at first thought I was going to blow an eardrum. I'm running them and rear fill Diamonds off Alpine MRP-F550. Mounted Speakers on door panels wher stock werem after dynamatting and flush mounted tweets top of door panels.

 

I wish I could have replaced the wire through the doors, but there are factory connectors at the outer panels that you can unplug. That stopped from being able to run my wires through the door loom. I sucked it up and used the factory crap, but I gotta tell ya....It hasn't hurt the sound one bit!
