Thinking about doing something different in my truck, please help!

Hey guys I guess because I have gotten my bimmer to where I want her with regards to sound maybe its time I do something to my beater pickup truck. The truck is a standard cab 1987 Nissan 4x4 with a solid shell on the back. Because I have literally no room behind the seats and doing a blow though is not an option, Im thinking of doing something creative but I dont know how it would sound. What I have in mind and what I need your opinion on is building a box in the font of the bed of the truck for 4 10's or 12's (really whatever I could get cheaper). The subs would fire straight up towards the roof of the shell. This whole compartment would be sealed from the rest of the bed and would port into the cab through the sliding windows in the shell and the cab, I would then seal the gap around the sliding window. The other option would be to keep everything else the same but remove the rear cab window and shell window all together and seal the entire opening.

How do you think this would sound?

it would sound like having subs in the back of a pickup it would probably sound better if the glass was removed. and do you mean the port will actually end at the window? that would be a big port, and would be really windy in the cab. i would just seal it off from the flatbed like you said, and get rid of the window (less rattling parts). then just have the subs in the back. it would be like folding the back seat down with a sub in the trunk.

What you need to do it have the whole bed have subs in it all the way to the tailgate with some cheap but decent 12's //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif like 2 rows of 6 type r's, tha is if you have a 6 foot bed, if you have an 8 foot bed then go with 2 rows of 8!

I guess saying using the window as a port was misleading. It really wouldn't be a port but just how the sound would get from the bed into the cab. So your reccomending that I remove the window on both the cab and the shell and seal the gap?

On another note, I was thinking about doing this with 4 8" Subs in an effort for the box not to go too far back into the pickup bed. Not to mention they are cheap. I am torn between the Tang Band and the Assassin 8" subs, does anyone have a reccomendation?

The pickup bed still needs to be functional. Thats why I dont want to do a blow thorugh and I dont want to use the entire bed as the enclosure. Occasionally I have to haul stuff for camping, biking, tailgating, etc, etc...

Could you elaborate on this?

use the whole camper bed etc as one of the chambers. use the window as a tuned port
