Alot louder with door open, not enough port area?

[Blue Fury 10+ year member]

Well i can open the box up to accommodate for larger ports but switching to slot would be a pain and not likely worth it. Honestly the options that wouldnt be to difficult to do is go 1in bigger on the ports. If thats not really a good option i might as well do 2 10s(get 500-600wrms a pop), or do you think i could do just as well with a 1-1.5k 12? I could just get a bigger 12 then do a new box or vice versa

I think you'll be chasing a dragon until you make a complete change in your setup.

hmm.. this thread is very interesting and hopefully will help me get that 150 sealed in my ext cab... on music.

you can try a new box, but I dont think it would help much...that's how single cabs are

my ext. cab is like that too. Probably loose 3-5 dbs sealed up

same here... I think a 150 sealed is possible in my ranger though... I have a decent amount of cone area, decent power, and plenty of port...

I compete in meca....doing a 52. And I might be able to do a 50 sealed up on a tone, maybe. Music probably wouldn't be close lol

ill "try" for it but nobody that ive heard of puts up big numbers sealed in ext cabs except Bojangles.. lol Ill def have a 50 outlaw though... Its a demo truck anyway so sealed score really isnt a big deal...

have you been on a meter yet? Buddy has 2 15's on a bc3500 in a ranger, it does good

not yet.. havent gone full power yet.. but Im building a new box, then I will do some testing between the 2 and make a choice from those two sets of numbers... looking back I should have gone with 2 15s... but we will see what that apxx will do...

Basically your car works as a 6th order bandpass.

wow a ton of wrong info on here.

I think @Kangaroux is the only one I saw that got it right.
It's not your windows acting as a port, it's not your cabin acting like an enclosure. It is all to do with wave lengths and phasing. A full length bass wave is much longer then the distance from your subwoofers to windshield. This causes it to double back, and go back forward again, until it reaches maturity and loses strength. This Causes it to become 180 degree's out of phase with the forward moving wave canceling each other out. Opening your windows lowers the amount of the bass waves coming back at the source as it lets them escape out the window. It is 100% to do with cancellation, once you get the perfect alignment between the subwoofer and listening area you are golden. Have you ever noticed that even with very low scores that HT subwoofers are much louder to the ear? That's because they don't suffer the same problem as an in car sub.

Exactly //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Ignorant people so quick to say I'm wrong.

Yes in effect your car is working as a 6th order bandpass.. Some cars work but not all cars.. If you get louder with windows open in effect it's a 6th order.
