I have a 2005 acura TL with sundown SA 12v3 right now in a standard L port box tuned at 32. Was looking to rebuild the system. 4th order blowthru maybe? The backseats DONT fold down but do have a "passthru" in the middle seat thats about 7 inches wide / 10 tall. Anyway, suggestions on subs? Not hating on any company. I just know that some subs do better in sealed / ported. I would be doing (1)! 12. Would be on around 3000 watts or so (2 strapped hifonics BRZ1700.1s) Wire - all sky high car audio Batteries- At the moment my 1700.1 (1) is running off my front battery (optima yellow top). Full tilt, doesn't go below 12.5. WIll be getting an XS Power D4700 eventually. \ Thanks
So I didn't know where to drop this topic so here it is... But im wanting to build a blowthrough in my 05' impala. I cant seem to get this figured out right. ive built sealed boxes but never ventured into this type. I got all my base numbers and all but lack the computer programs to make sure its all gonna be where I want. I just got three kickers cvr 10's. if anyone is willing to help id really appreciate it. I can post all the numbers I can work with.
hey guys, im wondering how to determine the tuning of a sealed section of a 4th order. i know sealed boxes dont ecactly have a "tuning" but ive heard they have an Fs. so in a 4th order, how do you get one to play really low? like below 20hz. ive also heard its good to tune the ported section to the sealed sections Fs. ive had a good amount of experiance with 4th orders so im just seeing how much of this is true. im wanting to convert my current 6th order wall into a 4th order for 3-4 FI SP4 18s and want it to play down to 20hz or lower. is there a formula for determining the Fs (tuning) of a sealed section of a 4th order? thanks for any input!
