i notcied today, when i was listening to Unk's "Walk it out", that when I opened the door to my truck the bass hit a LOT harder, same went for when i tried rolling down the windows. Is there a dynamic behind this? Is it because the air has nowhere to go when the cab is sealed?

 

yep. when the cab is sealed it's pressurized so it kind of dull's out the bass or something like that. my bf explained it once but i cant remember exactly what he said

 

yeah, anytime you want it to be loud, roll your windows down...lets the bass get out...

hmm.. interesting
yeah, that's pretty much how my dad put it,
haha i rolled my windows down and walked away from my truck and yeahh you can defnitely hear it alot betterr

 

same concept applies to porting a sub box..makes it louder ya know.

 

it allows more air to move which means more vibration (sound is vibration) which means LOUDER

 

yea ive had my bass on pretty loud, and open the door to get out and then got like twice as loud, i used to leave my windows down for that reason but after my rearview mirror rattled off i turned down the bass a lil =)

 

lmfaoo

 

I noticed the same thing. When mine is in a building, and the radio is turned up, you can hear the bass like 20-30 feet away, but when its outside, you can't really hear it outside the truck. I recently made a new box, and increased its size from .66 to 1.0 airspace (which is max for sealed box with the kicker l5), and it was amazing how much deeper it made the bass. The sub is on the passenger side now, but it feels like its right behind you.

 

i need to get sum pics of my boxes that i made, its not quite 1ft airspace but i got 2 behind the seats, hell with the radio HU on about half volume and the bass control at about 2/3s you get a massage with rock music lol

 

yeah dude, when i park my truck outside my garage you can hear it from about 10 feet away, but when you walk inside the garage its insane how much more powerful it sounds

 

i guess thats just how small sealed boxes work since most of us have single or extended cabs you cant get the biggest boxes in the world

 

yeahh

 

i have a small sealed box with a Kicker CVR 12, hits way better with windows down

 

yeah i have noticed that... and i NEVER listen to my music with my windows up anymore hahahaha
WOOOHOOOOO

 

All these guys are correct. My 800W sub sounded weak until I rolled down my windows and man, I thought I went deaf. It makes a huge ddifference
