Re: Sound System
You're talking from the realm of theoretical bla bla bla, I'm describing
real life. What happens in reality is what I said. If you don't believe me,
why don't you just get some hands on and try it yourself with a real BOSE
Audi system?
Then, and only then, are you in a position to discuss this.

Yes.
it's been discussed over and over. The Passat lies sizewise somewhere
in the middle and these days platform just means shared modular items.
Sharing they do.

Sheesh - first of all, Bose *anything* sucks, theory or not. Second,
don't talk theory if you don't want to be corrected when you're wrong.

Yeah dude, Ohm's law, basic current draws and voltage drops, that's
*really* theoretical stuff. So theoretical, in fact, that I learned it
somewhere around 8th grade in shop class.

Yeah, because the theory behind electronics and electric circuits has
*nothing* to do with reality, right? It's all just fairy dust and
magic, right?

Did you check the rated sensitivity of the replacement speakers? 'Cause
if you didn't, you have no way of knowing what caused the reduction in
volume. Could have been any of a number of things. But, unless the
amps in the Audi/Bose system are *incredibly* weak, the one thing that
*didn't* have anything to do with it was the rated impedance,
*especially* if you used *higher* impedance speakers. (Lower impedance
is a different story, as in that case, the amp might not be able to
supply enough current to drive the load.)
> Then, and only then, are you in a position to discuss this.
Gee, because you've installed a couple of speakers? I've been
*building* speakers for about 15 years now; I may be no Jim Thiel or
David Wilson, but I know at least a *little* about it - at least enough
to know that you, apparently, don't.
