Theory?

I've always wondered whether elevation would affect a subs performance, since subs work by pushing air, theoretically wouldn't a sub be louder at sea level than at a higher elevation. Living in Santa Fe, NM, this kinda made me wonder if my subs sound worse up here at like 8,000 ft (25% less air desity than sea level) than they would back home in MA at just a little above sea level. Or does elevation only affect O2 levels in tha air? Any light that could be shed on this would be cool, it's just something that I've been tossing around in my head for a while.

yes, your losing db's to a lack of air pressure. Odds are your car is a decibel less luod than sea level.

Not only is your car not as loud, but your ported enclosure tuning will be off because of the difference in the speed of sound. You will also have to re-EQ the car if you take it down in elevation because of the difference in Mach.
