That's how mine is acting now. It's weird.Any explanation is appreciated lol play with your port area. what kinda port area/cone area you looking at? I have 4 9515's. Port is 32.5x10x17 deep right now. Im thinking of shrinking it to 25x10x10 to keep tuning @ 45 but less depth. There is only 5" from the back wall to the port opening as it sits right now. I think it's choking it off or something. Below 30hz doesn't seem like it did when I had the 15's with 2 on each side facing each other like Ty's truck is now. I changed it to forward facing kinda like your truck but subs are inverted.Im working in a 2003f150 crew cab truck. 2 seperate chambers 3 cubes for each pair of subs sealed and 3.4 ported after all displacements for each sub. 2003 F150 Crew Cab Panasonic DVD Flip Out 4 9515F's Dual 2(i soft parts) 4 DD M3a's 350A singer alt 8 nsb 90's 1 Nsb 125 161.5 @ 46hz in the kick USACI Street Beat 4 2nd place USACI WF 158.5 @ 39hz LEGAL ON DASH 160's on music in kick
2003f150 Posted September 8, 2011 Report Posted September 8, 2011 my 4th acts a little funny louder sealed up on the lows... and louder opened up on the hi notes. i love it though Yea mine is louder with windows up and dont have much of the lows but windows down its crazy lowz! Oh really. That makes me feel a little better. Scott how much port area and how much ported space do you have in your box?? I want this thing to be brutal for demos and I like to do them windows down lol. One window down its a little louder than sealed up but you crack the other window you can hear and feel the difference. I tried both windows only halfway down and that don't work either. I guess I can play with port and all else fails demo with one door opn/window down and load my victim on the sealed up side of the truck. My old ported wall lows was better sealed up but high notes better windows down. I like it that way. I built the 4th order for more control and better bandwidth but its not quite where I want it. I may also move the subs back to firing into each other as that seems to do what I want better. Thanks everybody for the help! P.S. When I say I lose with windows down its anything higher than 40hz. It just doesnt hold the pressure almost like its not loading off anything.Roll up the window and bam instant bass boost. 2003 F150 Crew Cab Panasonic DVD Flip Out 4 9515F's Dual 2(i soft parts) 4 DD M3a's 350A singer alt 8 nsb 90's 1 Nsb 125 161.5 @ 46hz in the kick USACI Street Beat 4 2nd place USACI WF 158.5 @ 39hz LEGAL ON DASH 160's on music in kick
