Listen here's my prob, I had a 99 Ext cab, with 2 15" subs, and amp in the back seat, and I also own a bandpass box with 2 12" subs, and amp, I now bought a 96 regular cab, and I need some bass, any ideas???? the twelves are Type S Alpine, and the 15" are Audiobahn.

 

I've got a '97 standard cab. When I had a system put in, we went with an 8" woofer in a sealed wedge cab. I don't remember the brand, but it sits behind the center seat (on the "hump" over the drive train). You have to slide the seat forward to flip the center seat/console up or down, but otherwise it works and fits perfectly, and gives me all the "thump" I need.

 

A custom box for 2 12s with integrated amp rack is probably your best bet. I don't think a band pass or the 15s will fit, but I'd love to see a simple solution to make them work.

 

It is all about personal prefrence. Do you want tight bass (sealed) or loud bass (ported). Personally to me one high quality sub (Diamond or JL) and a good quality amp sounds great to me. Plus I did not want to take up all of extended cab.

 

I know in the 97 up you can fit 2 12's with a amp in a custom box behind the seat IF you take the time and design it right, that's how I did mine, i;m sure if you take time to design a custom box you can get up to 10's in a 96 maybe even 12's

 

In a regular cab I would agree with Unlawful, you will need to build a custom box for maximum rated air space for the sub(s) You might also want to check with your local car audio shop (not Bestbuy, Circuit City etc) because they have access to companys that build boxes for specific vehicles that you want to put a sub in. For mid quality subs, I would build a box towards the upper end of the recommended air space to get the best sound.

 

the alpines might fit. it would be easier to use just one of them for space reasons, but they both should fit. they require between 0.8-1.5 cubic feet per sub in a sealed box. i am currently building a box for my orion 10 that is 1.4 cu ft ported, but it has an amp rack on one side. if you mount your amp under the seat, theoretically you could fit both behind the seat. it might be easier to put one back there in ~1.0 cu ft box so you have room for amps or junk storage behind the seat. the box size is also a function of how much power your amp puts out. a smaller box is less efficient thana larger box.

 

The 15's id have to say are pretty much out of the question, unless of course you did some crazy modification, and even then...but i recommend gettin custom box with 2 10's, or you could try the 12s, not to sure the type S requiremnts, but i know my 12 inch L7s wouldnt fit in my L unless i was willing to sacrifice a little bit of leg room, but 2 10s would work great in a custom box.

I'd figure out how much airspace you have to work with then decide what sub to use. Most subs sound bad because the install isnt up to par, so dont make the mistake of buying a big sub and then having to put it in a box thats way to small otherwise it wont sound as good as it could.
I'd personally think 12's AT MOST, I wouldnt want to try it with anything more then 10's.

 

I had a 97 regular cab with 3 jlaudio 8w6's in a 1 cubic ft sealed box running a rockford 250.2 it hit extremly hard. If you want pic email me at twcpres@yahoo.com and I will send them to you. this was the final setup i had after putting 4 different amps subs etc...

 

I have a 2000 F150 and 2 Pioneer 12's in my regular cab. All you have to do is get a custom box made and you can pretty much put anything reasonable in there.

 

I think its MTX that makes a custom prefab box that fits 2 10's.

It comes in gray or beige (its a plastic spun material).
My stereo shop quoted me $150 for this box with no subs included. Only certain subs fit though due to space.

 

MTX does make a custom box for regular cabs. I was looking at it last week. It has one ten behind each seat and still allows for the center console to flip down. Not bad looking either in gray that matches my interior. The only bad thing is it takes up the entire back so you have no storage

 

Well I got a box for the 2 Alpine 12s, and put the V12 amp under the drivers side seat to run the 12s, and then put a Clarion amp under the passengers side to run the mids/tweets, and mounted a 12 disc changer behind the seat also, its a bit hard for me to get comfortable driving being 6'0 , 200lbs, but the sound quality out weighs the the leg space problem, thanx for all the help

 

I have a friend with a f150 reg cab and he has one 12" Kicker L7 in a ported box and that thing embarasses my current system with two 10" Kicker L7 woofers. He is using the Phoenix Gold 800.1 Octane amp @ 1 ohm. I am talking rediculous bass for a reg cab truck.
