I've had a regular cab ('02) & a CC ('05) with MANY different setups short of a blowthru. And every setup was louder with windows or doors opened vs sealed. :dontknow:
As I understand it, it has something to do with the suspension of the subwoofer. Just as a sub needs the correct airspace inside the box, the volume of air outside the box also comes into play. Having your windows down will make the sub see essentially infinite airspace outside it, which depending on the airspace inside the vehicle (and possibly the box design) may make the subwoofer perform better or worse.I'm sorry, I don't understand that statement. Can you explain?
lol no comps for me, lol. I'm just tryingto get louder inside without bothering everyone outside, hahahaha. Question for you, with tuning that high with cabin frequency, how does it do with the low end? This setup is a daily beater.For the ext Silverado it should be tuned around 54hz no wall and tons of port area and you will start to see your score come up sealed, that's all the info I will give you because some day you just might be competing against me lol.
