subs
so i got two new 12'' kenwood subs and i was curious about how some of you fit two of them in the truck, did you build your own box or did you get some other special fit boxes because i was thinking about building my own to fit perfectly under the back seat but i just wanted to hear what you guys did to

a local audio shop here in town has one that fits under the back seat on quad cabs for about 100$. i bounce between my 12" sonys that have huge boxes that keep me from putting my back seat down and my 12" jbls that fit perfectly under the back seat. the sonys have 4x the punch as the jbls but like i said they're huge. the only reason i don't put the sonys in the jbls boxes is because they are too big and need a bigger box to sound right and not blow the cones off.
you need to take into consideration that each speaker requires a certain amount of air space (cubic inches) in a sealed or bandpass box to sound right and not blow. i believe crutchfields site has a calculator for how much space you need for different speakers and how to calculate it. but if they don't you can go to the manufacturers site and find it there.

My box is only a single 10 under the front middle seat. I know you can get 2 tens under the rear seat, 12's I'm not sure about though, might be hard to get the right area in the box.
Like Sheriff said, check out what the manufacturer recommends for cubic feet of area and plan accordingly. I'd say go to Crutchfield and search for your model number, and look at what the manufacturer recommends. I wouldn't use any basic calculators because every manufacturer is different. I just looked at the couple different 12's they had at Crutcfield, and if it's shallow mount you need .8 a sub, if it's more the standard size, they want closer to 1.25 for a sealed box.
It's easy to build a box with a few tools, but personally I wouldn't bother putting a sub in unless you could get really close to the 'ideal' box size of the manufacturer. I have my sub within .03 of the 'idea' for the Kappa, and it kills. No one believes it's a single 10" sub.
