A question about the factory sub-woofer

I never claimed to be the sharpest pencil when it comes to understanding stereo sound systems. Especially the one in my 2013 Longhorn. The premium Alpine system sounds great but I don't understand how the sub woofer sound is supposed to get out when it's completely closed off by the cover under the right-rear seat. Would someone explain that to me please.

I notice a bid difference when I open the cover over the sub woofer so why cover it up?

All about acoustics I'd imagine. Always want to feel the base as much as hear it, some insulation helps that. How many times have you ridden by some idiot in a Caprice or Crown Vic rattling apart at the seams because they have it cranked to the max and nothing to insulate the vibrations of subs? I've seen it all to much.

I mean if you don't blow out your ear drums with your stereo system covering or not don't make much of a difference. But if you got your bass pumping it helps to insulate so you don't hear your windows rattling in there tracks.

I've lost the hearing in my right ear so I'm not able to appreciate the sound quality like I used to but the bass sounds better to me with the cover open. Maybe I should cut a hole in it huh?

I hear you about the covering up aspect of it, but every sub woofer I have had has always been in a box like chamber. Also the Sub woofers are not meant to hear the direction they are coming from because they work under the omni directional principle. When you talk to an acoustic guy he will never say you should have your subwoofer at a specific location in the room of a house. So positioning specifically under the passenger rear seat is not a concern. I think my "Alpine" premium 9 speaker stereo system that came with my truck is pretty kick A** so I'm loving it.

From an audiophile guide:

Humans hear frequencies from 20 Hz up to 20,000 Hz. The lowest bound, 20 Hz, with a wavelength of nearly 20 meters, is a frequency we feel rather than actually hear.

A sealed space, or pressure chamber, lifts the low frequencies by 12 dB/octave below a frequency related to the dimensions of the enclosed volume.

So, I'm assuming from this, they get away with lower quality equipment to get the desired sound output by doing the enclosure this way.
