Car stereo question

What’s up with putting large speakers in the trunk? Also, I once bought a 2-seater that had some 12" speakers in boxes behind the seats so that any sound coming from them went right into the seat and was presumably dampened as a result.

This seems crazy to me. But maybe I’m not getting it. Is it the case that lower frequency is not hampered by stuff like this?

The low frequency is dampened by being in the trunk but in that case, two subs in a two seater probably compensated for it.

Plus in a two seater, where else would you put 'em?

I think facing the speakers toward the back of the seat as opposed to facing them upwards reduces trunk noise and vibration. And bass feels good. I like the vibration.

The low frequency waves are hardly attenuated by the seats. There’s really no other place to put the subs in most cars. You can put them under the back seats in some trucks, which is pretty cool. I’ve got a couple of 12" subs in the trunk of my Charger. It sounds really, really good in the front seat, but sounds really muddy in the back seat (a large part of that is the way the balance is set). Mine actually face towards the back of the car, but it doesn’t really matter. There’s a lot of air being moved, and there wouldn’t be as much if there was no circulation allowed (if it were crammed against the seat).

The large speakers are subwoofers and play sub frequencies. They reproduce such large wavelengths that they aren’t hindered by obstructions.

That’s why you can hear these cars sitting inside your house as they drive by even when the car is sealed up.

BOOM-BOOOOOOOM
“Who listens to music like that? Just bass.”

Probably not. To the person in the car they are hearing all frequencies of the music, highs mids lows sub and it blends into music. For the outside observer/listener all they are hearing is the subs since the other frequencies ARE being blocked out by obstructions.

The couple cars I had with subs I tried facing them in either direction to check them out and they definetely hit harder facing towards the rear of the trunk than facing the front of the car.
