>well, that's what I thought, that they were "normal speakers" but then I got talking to my buddy that used to work at a car dealer, and he starts telling me about these infiniti systems having a non-amplified head unit and individually amplified speakers - he sounded like he knew what he was talking about...and who among us would put it pas DC to do something like that if it would save a buck. I guess I will just file that in with Josh's BMW muffler bearings...
I read several posts in the newsgroups about that when I was first
buying speakers for my truck. As it turns out, though, at least in my
'00 SLT CC with the Infinity system, there is a separate amp that's
behind the kick panel on the passenger's side. I just replaced the
speakers (both front and rear) and they work fine.
There are a couple of odd things that I noticed. It was several years
ago, but here's what I remember.
1.) The front speakers are different from the rear speakers.
(Slightly different shape and different model number stamped on them)
2.) The front door tweeters stopped working when I replaced the front
door speakers.
3.) I replaced the factory head unit at the same time, so that might
have something to do with this.
It was all somewhat confusing to me -- I'm not sure where the
crossover exists for the front door tweeters. If I remember
correctly, there's just two wires per channel going out of the factory
amp, so the signal had to be split somewhere. If the crossover were
external from the midrange speaker and the tweeter, then the tweeter
should have still functioned after I replaced the midrange speaker.
But it didn't. Since the front speakers are different from the rear
speakers, it's possible that there could be some sort of crossover
built into them. But that still doesn't explain how the signal got
from the midrange/crossover to the tweeter, since there were only two
wires going into the speaker. I still have been too lazy to dig
through the wires and find out where the wires for the tweeter go.
