Ah - my bad. But they are all very similar. The Infinity car

They come out of the same factories and are made to spec per the
auto-company's engineering department. This means that if the auto-company
engineer who is in charge of the JBL-branded system is more skillful and
demanding than some other auto-company engineer who is in charge of a
Levinson or Infinity-branded system, he gets the better drivers, and the
better sound.

I've heard both - not hard when I used to live 3 miles from the
Northridge campus - and the Infinty car speakers are a bit
better overall, but they do charge way more. I think they take the
slightly better drivers and label them as Infnity.

It *might* be that the goofballs at the factory put a normal
factory stereo that is meant to drive 8 or 10 ohm stock
speakers in with a set of 4 or 6 ohm Infinitys.

Highly unlikely. OEM drivers are almost always 4 ohms or below because
switching power supplies are for all intents and purposes, no-nos.

My GM factory radio is set up to drive 4 10 ohm speakers. It will
not reliably drive even a single pair of 4 ohm ones.

Course it's GM - so all bets are kind of off. Lol.

You see - they put in the stereo first sometimes and sometimes
the speakers first - then slap the other unit in, so if you get
a "upgrade" package, sometimes they weren't really tested/mated
to work well together.

That was then, this is now.

Well, it's not inconcieveable that something might slip past the
rubes you are more interested in shaving pennies than making a good
audio system.
