I need a box design for under the rear seat of my truck but the thing is I don't know if I want to go with four ported 8's with about 600 watts a piece or two 10's ported with about 1000 watts a piece...which setup will be louder? And who is a good enclosure designer?

Did you buy a new truck? That won't fit in your crew cab unless you are seriously clever with fiberglass.

it's a new body style crew cab... which setup will not fit?

Neither of your choices will fit. Not even close.

i have the airspace so if you dont mind explain to my neither of them will not come close

err, where is this said airspace? It isn't under your seat.

yea...I have 3.6 cubes before displacement

Under the seat of a Crew Cab? Can't even get that under an older E/C with a seat lift. You need to remeasure...

I measured a few times before I posted the thread..I saw a few installs with four ported 8's and dual 10's

Just because you've seen installs doesn't mean they are worth a shit. Getting 1.25cuft net is not trivial, more than that is a pipe dream. Get the box built/designed first as your early measurements and reality aren't going to line up.

You only have about 2.5 cubic feet gross under that seat with no lift. I have a 2010 sitting in my driveway.

I have a 3 inch lift on my 09 crew. I had about 2.6 cubes net. With 4 8s ported externally.

so I do have enough room for two shallow tens or four ported 8's... correct?

Two 10's could squeeze depending on the sub's requirements. Four 8's ported would not.

so my best option would be the ad series from sundown

SD? They have a small enough Vas that they'll work in the volume. Not sure of the frequency responce, I'm sure it'd be ok, I don't have stuff with me to calculate by hand.

And that is you building a box. I'd shrink it a bit to be safe which to me means 2 sealed 10's.

If you want ported and 2 of them you are going to need to be creative or lift your seat. A single 12 ported will work though.

with that being said shoud i look for subs that excel in sealed enclosures?

Or run a single ported 12.

B4 shopping though, I'd design the box.

Definite must. That's how I begin every build. Save time from guessing.
