EricM9104 Posted August 30, 2009 Report Share Posted August 30, 2009 Army guy you have resonded twice to something that you have NO knowledge of.....so while appreciate you resonding I think that this thread is a little out of your league......Thanks If you are familiar with the T2000bd if has a infrasonic switch either on or off, there is a gain, there is a freq knob adjustable from 32 hz to ?, and a master, slave, and single switch..... The infrasonic is on, gain at 1/4, freq is at 45, and single is switched.......took the truck out and it is still bottoming out........the BTL's cant handle it.......as far as taking a pic.....the way the amps are mounted you wont be able to see anything....... infrasonic is the ssf, set at 27-28hz automatically... the 45hz setting he's talking about is the lpf.learn amps, dumbass. 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...
XXXD Posted August 30, 2009 Report Share Posted August 30, 2009 wat sort of dimensions have you got to work with because if your are dissapointed with the output of the btls maybe a 6th order bandpass box could be a good move Link to comment Share on other sites More sharing options...
Sanitarium Posted August 30, 2009 Report Share Posted August 30, 2009 good luck keeping those subs together with 250" of port for a 10ft box thats 25" per foot subs are not gonna like that daily you act like he is running lms or xxx with huge excursion the btls will be good in 10ft and 150" of port I have heard them in that box before straight swap from MT's sounded great for btl's the more power the less box and port used unless you don't use them daily I will be running 4 15's in 11ft in my blazer so I can keep my subs together with 5-7k each subI'm not gonna argue, I just know the accepted formulas for building boxes.Heres a good calculator based around those formulas. http://www.carstereo.com/help/Articles.cfm?id=31 2 x 18" subs w/ 28mm xmax @ 33 hz actually calls for 283^2" of port. Anywho. Even Fi's recoomendations of 12 to 16 ^2 per cube puts you at 120 to 160. Which was the point all along. 100^2 is just too little. Edit: Sorry that's 12 to 16^per cube per sub. so 2 subs = 24 to 32^2 per sub per cube. with 5 to 8 cubes recommended per sub. Link to comment Share on other sites More sharing options...

If you do that he's going to be slinging the soft parts out on the ground..that calculator is terrible. Not to mention his port would probably be close to 8 feet long with 283 square inches of port...to tune it anywhere decent. Follow our guidelines, do what we say to do.
