eww prefab box as a blowthrough

basically, build a bed-box that is waterproof, and cut a hole in the back of the bed\cabin that are about the same size, and find some wide-gasket spacer stuff and seal the gap between the two areas. seal the bed-box to the back of the truckbed (bolt it down to the bed from the inside too) and fire the subs thru the hole.

bout as easy as you can do it.

if it were me, i would get somone who can weld, and weld some support to each area you are cutting before you cut, maybe you can rivet, but tis not as strong.

good luck :)

prefab box in a blowthru........hmmmm.....i know how to weld and im gonna support it i just wanna see some picture of finished products before i go cutting on sumthin and not get what i hope for ya know.....just shootin for ideas

I really want 2 do that but............it just seems to expensive........how much is that costin u?

12-10-2005, 04:05 AM
if you do it yourself, it's only pretty much the cost of the normal audio stuff (subs, box, amp, wiring) plus maybe $50 for the rubber gasket and some other misc. stuff.

labor for something like that someone would probably charge you either a shitload (like at a car audio shop) or next to nothing(at a local body shop).

if you can weld and ****, do it urself :-) it'll be a cheap, good project. i was wanting to do it to my 2000 single cab silverado, but decided against cutting up the body of a somewhat new truck.

Me 2........I just dont think its worth it 2 be honest

according to my stereo guy, blow throughs should be a ported box tunneled into the cab. the front baffle literally needs to be tunneled through into the cab by extending the external walls if that makes any sense. either you could fiberglass it or carpet it and put a tonneu (sp?) on the bed.

i was accually thinking of doing 1 15inch MTX RFL woofer in a big ported box not sure what size yet...and i was gonna coat the box in resin and cover the part in the bed with diamond plate

eww prefab box as a blowthrough


The 25th, 27th and 28th pictures on top show him with a better install.

12-10-2005, 04:37 AM
oh, and you have to use a boot in between the bed and cab, to keep it waterproof.

12-10-2005, 04:40 AM
yeah i got that covered i have an accordian boot used for campershells

i would do it but i dont until the trucks paid off. when i notch the bed to air bag it il do it. but until that no still got about 3 years left of payment so im not cutting anything now lol

12-10-2005, 06:06 AM
lol my orignal plan when i get it was to bag it...but ibeams are a ***** and expensive so its lowered 2/4 coils and flip kit...but i've figured out what subs im gonna use im gonna get 2 15inch Orion XTR pros i had 1 back in the day and it was loud...im gonna see how loud the lil ranger can get....i also plan on getting either ID Horns or some Wave guides with 2 7inch midbass's....im gonna buy all this stuff at once i got about 1300 saved up for rims im gonna use for this project...still need to scrape a few more hundred together to get everything..

oh yea and if anyone wants to buy anything in my sig except for the cd player and memphis belle let me know its all forsale in the forsale section

I wanted to add that when you start cutting; make sure to start cutting from the back of the bed.
the key to a good blow through is to measure 100 times before cutting.
get a drill, good cutting wheel and a sawsall and you are ready to cut.
the accordion boot shuld be easy to find at your local camper dealer. use lots of RTV to seal the boot once it is in place.

I have a nissan regular cab truck and as you know this is a little truck, so the biggest subs i could put behing the seat were these little two 12w6v2's;
I can say i am really happy how it turned out. I got the box bolted down to the bed and as you can see on those pictures i used alot of the P&S from Lowes.

thanks guys!
the amps have a cover that once it is in place it covers everyting except the top of the amps. Inside the cabin i made a panel with a rounded shape that covers everything except the speakers. I have to upload this pictures soon for a finish product update.

yea man i was looking at that last night on the gallery, great install i use to have a truck just like that one about a year ago, the more i tihnk about it i wanna do 2 12s also...because the box for two 15s would stick up about and 1 1/2 over the bed, so im just gonna go 2 12s ported...and im gonna do a nice glass install in the bed after i get a tonno cover...any sub suggestions would be great...im kindof confused at the moment im looking for mostly SQL 50/50 sq n spl
