4th Orders, ported through the rear window? (Trucks with Campers)

[Cardboardcat15]

Anyone else ever done this? All I've found so far is John Hone's Truck. I've got an 01 Dodge Ram 1500 Single cab with a camper shell, and 2 sp4 18's sitting around doing nothing. My original plan was scrapped because the car they were going in (1992 Corolla) is toast. I DO NOT want to cut through the rear wall and do a blowthrough.

Here's what I've found so far.

I'm hoping it'll work, but I wanted to get some educated opinions on this. I figured a 4th order ported through the rear window would be pretty cool, even if it is only for 2 18's. Thanks for any input fellas.

That's how we have to do all the big truck builds in Australia

If we get caught with a blow through they'll put our cars off the road indefinitely

Most of us just do a normal ported box

And remove the rear window and for accordion rubber

So it just like a suv

Put it this way more sound goes over the rear seat then through it so where's the difference

And depending on truck you may still have a rear section to haul stuff around

Yeah, thats exactly what I had in mind. Would building a shell around the box change the output much?

[john253a]

Personal I have never done it or seen it

But idd reckon yes

As you'll get a lot of flex from the glass roof so a lot less output and sq

You can get short toppers as well which only cover 1/3 or 1/2 of the length of the box if you dont want to have a full-length topper

Well the thing is ive already got the camper shell on there. The issue is whether or not a design will work. Im just curious to know if this has been done a whole lot so I can possibly get some ideas on a design.

Hank has doing it still in a f350 dual lot 4 door

I think he has something rediclous like 20+ subs

If I had a truck I would do window blowthru or just walk thru that bitch

I've seen them done a few times. To me there's not much difference than cutting a hole as far as sound. Just more work

Look up a guy named Hank Veach. Has had 48 sa-10s in a blowthrough like you describe. Could to a 160 sealed up on the dash at 30hz.

I don't care much for the character, but I loved that truck. 160, plays all day, plays low, and has the back row.
