Yet another thread on blowthroughs

[G_skillz81]

Whatsup everyone, new guy here...old question though...I'm in the midst of reading up the threads on the subject (will probably have a much better idea of what's what by the end of the weekend)

Anyhow, the truck is a 2003 reg cab Ram with a hard bedcover

First question - where to get the accordion boot to cover the gap in the cutout between the bed and the cab? I've searched for it, but could find any place that sells them

Second question - I've got 21 inches of space under the cap...most people run 12's and 15's...can i run dual 18's firing forward? (the subs are custom built 18's on a TC Sounds TC3k motor - overall diameter is 18.5) - or is this not a good idea as the cutout will be noticeably smaller? (I think 15" is the max height of the cutout I can get in there). And it will be a tight fit witht the sub jammed tight against the top and bottom plates. Not a problem to switch subs really, but I do have one of the 18's already (beating in another ride). I am limited to TC3k motors but can get them as 12's or 15's....either that, or Adire Brahmas MKIV

Box design - I'd be willing to pay for a set of blueprints ..I've pm'd James with a request already, but if any one wants to take a shot at it, holla at me

i believe the gasket you need is sold at Rv centers . that would be one hell of a tilt on that baffle for 18s just imo id go 15s

Thanks for the tip!

I'm thinking I can fit them without a tilt... The MDF I'm using is close to an inch thick (I'm overseas, it's metric - 240mm. an inch is 254mm), so accounting for the top and bottom I have 19" to work with for the baffle. The only problem I potentially see is that the height of the cutout will probably be 12" max (what are the recomendations for the cut dimensions??) so that may really choke the airflow....or am I thinking too much?

Guys? who else could I pm for a design for $$ on the blowthrough? I'm not getting a response from James

Here's where I got my boot seal.

I've got an '05 Ram and if your bed is like mine, it angles away from the cab at the top. Make sure your seal will reach before you go cutting a 12" tall hole. I cut just below it starts to get wide and my cut out is only 9" tall.

i believe mine is 11 1/2 inches tall. went from as low as i could go in the bed up to the seam below the upper brace. my vent piece opening is 11" and I have 1/4 " MDF on top and bottom with just barely any clearance

[G_skillz81]

Thanks for the replys guys! really appreciated!! I've sent a pm to Patrick (pstone11) hope to hear from him soon

I'll try to get under the truck during the week and see what is he max cut I can get in there. When looking at it before, I found 15" between the cab's braces (that's too much for the bed though). What is the distance between the wheelwells in the Ram BTW?

2Darren - great bulid! Did the MLA module make a big difference? I'm thinking about getting one. I will also be running RF T20001bd's (one per sub)

scroll down for accordian boots, it's like 8 bucks a foot, took me like 10 seconds to find 100 websites that sell the material

there is 50.5" between the wheel wells my box is 49" wide and i used some 3/4" scrap pieces to keep it from shifting from side to side. The MLA works great use to drop voltage to 10v before it and now it doesnt drop below 12v. PM me if your needing a T20001 i'll be upgrading soon.
