cjvue Posted October 28, 2011 Report Posted October 28, 2011 Ya, I had my box made and originally was supposed to be 3.5 cu @ 35hz but they made it 4.1cu @ 31hz. Kinda really pissed me off. And the show also set up my gains to my BTL 15 and blew it. Now I realize if I want it done right, gotta do it all myself. On what power? I have no experience on btl but have seen they take a beating. If 4.1 cu @ 31 hz blow your sub then either there is clipping signal, way over power, or you're playing way lower than tuning.

Hifonics Posted October 28, 2011 Author Report Posted October 28, 2011 Clipping. They don't know how to set gains. Won't be going back there again. I'm getting my own DD-1 and they can suck it. lol Quote 2010 F150 FX4-18" AA Mayhem-Crescendo BC3500d-Pioneer GM-D9500F 4-channel-2 Crescendo FT1 -2 Crescendo Neo Forte 6.5 -Pioneer AVH-P3300BT-6000K HID Headlights/Fog lights-All LED interior lighting-20% tint on front windows, 1% rear windows, 5% windshield strip-Big3 (XSFlex 0ga) -DC Power 270XP -Group 65 NorthStar AGM battery Coming soon/plans: -Build log-Blacked out mirror reflectors-Tinted tails/3rd brake light
cjvue Posted October 28, 2011 Report Posted October 28, 2011 If your box is tuned to 31 hz, then the sub will unload on frequencies lower than that. At 20 hz for example, your sub will be flopping around without any support in that box and will be making almost no sound. If you want to play 20's, tune deeper. But if I set my subsonic to lets say 28hz (with a 31hz box), it will be ok if the sub has a Fs of 38hz? I would say yes if net volume is appropriate for the power. Americalegand has a good point, but then again thats is just lower frequency reproduction. Power handling is a different variable depending on net volume and port area.

But i don't know thefull box spec so cant say it exactly.
