I'm trying to understand how it's possible that I've managed to create the best listening experience either of these educated and well listened people (one is a musician in three bands, the other our good friend Tom) had every experienced for significantly less than $1000CAD? It seems absurd to me, even though I also think that it's the best I've personally heard. How is this possible?


This is in Car Audio because I want to know the physics behind this, the reason. I want to figure out why my vehicle sounds as good as I and others think it does, especially for such a relatively simple system without extraordinary or expensive equipment. Most of you are familiar with the specs so I won't bother here. It's somewhat basic, but there's nothing of the stock system left except for the rear speaker enclosures.
MY MIND IS FREAKIN' BOGGLED!
The questions I have:
#1
Is the large interior airspace size of my vehicle an important part of the sound? Does the fact that the sub is in the same airspace as my ears and body make a difference to how well a sub blends with the rest of the spectrum?
#2
I haven't sound deadened a single bit of that truck. There is a bit of a heavier mat under the carpet but it doesn't seem nearly as effective as a real sound deadening job would be, especially since it's not secured to any surface. The dynamics can't be that great, can they?
#3
I'm not pushing that much power. I'm doing MAX about 45-50W to each channel of components (woofer AND tweet) and maybe 100W or so to the subwoofer. I don't know if the amount of power I'm driving the woofers with is all that important to SQ and listening experience but I don't suppose 40-50 for the components or 100 for the sub is really all that much. Does perhaps the fact that I'm NOT pushing a lot of power (but using the amp quite effectively as those are right near rated max numbers) play into the SQ of a system? Does SQ usually decrease with power? Increase?
#4
How much do I owe to PG?
#5
How much do I owe to the install? Did the fact that I used pro and very, very good amateur advice the whole way make the whole difference between fucked install and proper install?
#6
Are me and my friends totally delusional?

I have a feeling about some of these but I have confirmed my beliefs or inclinations (especially that delusional one...).
