shotokan_teen Posted July 3, 2007 Report Share Posted July 3, 2007 I KNOW that doing a blowthrough is going to be risky and tough but I'm willing to try it. My question though is what type of blowthrough will yeild a louder db? I was thinking of taking 2 sealed boxes (w/ maybe 2 15's in each), facing them towards each other and porting them into the cab. How loud will that be vs. any other kind of setup? Quote Link to comment Share on other sites More sharing options...
Chris Posted July 3, 2007 Report Share Posted July 3, 2007 The one you suggested is probably the most popular way of doing it, & will yield a high SPL no doubt with 4 15"s.

shotokan_teen Posted July 3, 2007 Author Report Share Posted July 3, 2007 I have 6000 watts, the electrical to support it and i'm LOOKING to do a blowthrough. My question is will this satisfy me? I'm looking at a couple different options... 1)4 15" Fi Q (or Bl) vs. 4 15" Fi BTL I don't know which ones because yeah the BTL is supposed to be louder but they wouldn't get the full 2000 watts they say, I'd only be given em 1500 apiece 2)Should I do 15"s or 18"s? I know 18"s are louder but will it be THAT much of a difference. Besides...I think I have the smallest amount of watts on this forum. Will I be doing those 18s (or 15s for that matter) any justice? 3)As far as the blowthrough goes I was looking at 2 sealed boxes facing each other and porting it into the cab. Is this louder or would "subs up port back" be louder? I just don't see how I can make this work. Quote Link to comment Share on other sites More sharing options...
BassJunkie Posted July 3, 2007 Report Share Posted July 3, 2007 (edited) Pics of said truck? Go with the BL's if you're using that wattage.

shotokan_teen Posted July 3, 2007 Author Report Share Posted July 3, 2007 The one you suggested is probably the most popular way of doing it, & will yield a high SPL no doubt with 4 15"s. is it really as easy as people say it is (as far as building the box goes that is?) I was going to build the boxes, rhino line them and port em into the cab. thats it?! Quote Link to comment Share on other sites More sharing options...
shotokan_teen Posted July 3, 2007 Author Report Share Posted July 3, 2007 its a 2004 F-150 standard cab. i know yall hate these questions but how loud are we talking? I mean is more better cause I originally was going to just do 2 15" mojos. Quote Link to comment Share on other sites More sharing options...
sean 371 Posted July 3, 2007 Report Share Posted July 3, 2007 6k watts is not anything to be ashamed of, thats a crapload of power for sure. Try to aim the subs forward if you have enough mounting area, if not, do a clamshell type box. You can get intricate with it and design it to be a sixth order series tuned bandpass box if youd like. And I'd go with 2 BTL 18's or 4 BL 15's. The 15's would probably get louder. Either way the box size would be about the same. As for the actual blowthru, I've never done one so I'm not too sure on the specifics.

Forevrbumpn Posted July 3, 2007 Report Share Posted July 3, 2007 hey man, keep it ballsy, yet simple, use those mojos in a bandpass design, use each 15 on either side in about 3cf sealed firing in to a 5/6cf ported box, and use the largest port possible to fire in the cab... all you would have to cut thru is the port... box in the bed, glass it, then rhino line it, then clear coat it, maybe a big 10" PVC port for the blow thru... thats what I would do Quote I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.
