Ported Box In A Standard Cab Truck

[Blackedout]

Right Now I'm running 2 12'' cvrs in a sealed box, about 3 Cu Ft After displacement. I want to build a ported box, because I have room in my truck to Make a box ~9'' taller than the existing one. My question is, what frequency should it be tuned to? Port(s) to the side(s), top, bottom, or front (firing into the bench seat). What is the most efficient port design to increase air space, since its limited, a single port or double? Anyone think this is a bad idea? Nobody around here has a ported box in a standard cab truck. I like the way a ported box feels vs. a sealed box.

I'm running a kicker 1000.1 amp.

Any comments greatly appreciated.

i have been told that the best sound and air movement for a tuck are the port's should point to the sides. the tuning freq should be what your woofer calls for. just remember for every cubic foot of air space you should have 10 square inches of port. this will still move air and sound amazing. my box is 9.2 cubes with 92 square inches of port, with a 10% port differentil is still hadles the lows amazing and sound even better

So the dimensions of my box are Width: 45'' Height: 15'' Bottom Depth: 9'' Top depth: 6'' Subs: 2 12'' Before displacement: 2.04 After: 1.78.

I was way off. I don't even have the minimum recommended volume. My subs sound great, and seem to perform well.

Heres what I want to do: Width: 47'' Height: 23.5'' Bottom Depth: 9'' Top depth: 4'' Subs: 2 12'' Ports: 2 Port lengths: 10'' Each, Port style: Tube (http://www.amazon.com/Precision-Port-Flared-Tube-Kit/dp/B0002ZPR4W) Port tuning frequency: 34 Hertz Before Displacement: 2.83. After Displacement: 2.46

The subs handle 25- 500HZ. The recommended Airspace is 1.75 Cu ft for each sub. I'm about a cubic ft short. Bad idea or go with it?

Thanks for your input, I appreciate it.

It wont drop bottom quite like other setups would, but 1.25 cu ft per sub net will work aiiight...I would do one port to either side, drivers or passengers, not both.

use winISD and get the box tuned to as close to 32 hz as you can. If you can run ports out the sides low on the box but keep at least the width of the port distance away from the side wall of the truck if you can't do that fire the ports up.

if possible run one woofer in the entire space and use the extra volume for a bigger port.

my last experience 1 15 vented was louder than 2 15 sealed.

although the power was not the same, experiment to get best results

here is a box i did in a single cab ram....it had similar dimensions as yours. it was for one 12Q with two 4" aeros out the side, tuned to like 30hz....it was like 2.5cubes after all displacement..

I will experiment with one sub and two, make a couple different boxes. Right now, I'm just in it to learn. I can't pull great numbers with such a small truck, so all I can do is work with the equipment I got and build around it to make it sound better/ louder.

Thanks again, everything helps.

I've got a reg cab with 8 12's ported so you have plenty of room, it's just in the bed...

Was thinking about it, but it wouldn't make sense. I'd have to throw down $500 on a tonneau, a $1000 on subs, $200 on dynamat, $1500 in amps, $100- $150 in wire/ connectors, $100 on building the box, $300 for mids....... $3700 in a truck worth $3000....

Btw, your trucks look bad ass.
