Voodoo Posted March 24, 2010 Report Posted March 24, 2010 I have a 92 Chevy caprice wagon with about 47.5" of width, 23" of height and 23" of depth to play with. I am having major trouble trying to do my own calculations on these online programs. Maybe I suck because this is the first vented box im building, but pleaaaase help if you can!!!!
Voodoo Posted March 24, 2010 Author Report Posted March 24, 2010 Oh and if this helps, I plan on pushing this with a PPI 2350 1800w rms amp and I am looking for a freq around 30 hz
Basshead08 Posted March 24, 2010 Report Posted March 24, 2010 SPL design tuned to 30 hz? System tear out has begun...Out with the old i have a iq of 128 i graduated at the top of my class tell me how im reatrded you are the 1 thats dumb as hell you can't even spell Look at the underlined text hahahahahahahaha I think of it as the virgin losing the virginity technique not just jumping in to it, and pounding away, but going at it slowly over time, to get to that full extreme
99xtremedime Posted March 24, 2010 Report Posted March 24, 2010 If you only have 1800W the you should get a fully loaded BL instead of a BTL. 1800 on a BTL is WAY underpowering it! -2 AQ HDC3 15's-'Nendo 3KWP @ .5-7.75cuft @ 30hz-Alpine CDA-117-4 Cadence PA 8's -AQ 200.2-2 AQ Supertweeters-XS Power D3400-270a Mecman Alt -Knu Konceptz Wire
Boon Posted March 24, 2010 Report Posted March 24, 2010 Jeez man... for a bit of a noob you're way in the deep end here. I'll try to be gentle but I have a habit of reaming people out... 1. 30hz is not an SPL tune. 2. Your first ever ported box... is an SPL box for a Fi BTL 18? That's.... ambitious. 3. A 2350 doesn't make 1800wrms and is a terrible amp for a BTL 18. In short, I think you're going about this all wrong. 10.x volts fo' life!
mxer111 Posted March 24, 2010 Report Posted March 24, 2010 Boon said it all. But everybody starts somewhere right. This is a good place to ask questions though. Good luck with the build Looking for a CRX to get back in the game. And a gas tank for my 01 r6. Hit the PM
Voodoo Posted March 25, 2010 Author Report Posted March 25, 2010 I apprechiate the constructive criticism. To clarify a few things, I am NOT burping the sub, I will be playing mainly bass heavy rap , screw, pretty much anything with crazy lows in it, and the 2350 is completely overhauled on the inside and its been bench tested to do 1800 wrms on only 130 amps and Im running 240. I understand the sub takes much more power, but this is what I have for now. I could reeeeeally use some help on the dimensions guys. I used RE audio's enclosure calculator so far, and Im just trying to see if i could get some better dimensions on here

I used RE audio's enclosure calculator so far, and Im just trying to see if i could get some better dimensions on here unless your running 16+ volts i doubt that amp does 1800 pulling 130 amps. because 14.4 x 130 = 1872watts of input and i doubt that amp is 99% effiecent. Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol
psx2p Posted March 25, 2010 Report Posted March 25, 2010 Just curious, for SQL who wants the richest/deepest bass what should he tune his subs to? 01 GMC Sonoma 4x4 RF T1500.1bd DC LVL 4 12"
