Hello all...

I recently installed a radio and stereo speakers in my car. The
speakers were a trashpicking find and they seem to work just fine. At
the time I wired them up, I didn't know which terminals represented +
and - on the speakers, so I took a guess and wired them both the same
way. The speakers had no marking to indicate polarity, other than a
"thin" spade lug for one terminal.

Just the other night I found the box the speakers were in. It has a
detailed wiring diagram on the side. According to the diagram I have
reversed the + and - connections on both speakers.

Over the years I've read a number of different views on the effect of
wiring speakers with reversed polarity. I've heard everything from "it
won't really matter if the speakers are both wired the same way" to
"the sound won't be as good because the speaker cone will pull inward
instead of being pushed out".

It wouldn't be hard to fix, but should I bother correcting the
polarity?

All that it matters is what they are all wired the same why in your car.
But if you want to make sure you are wired as the others, follow the
code/
It does make a difference.
for example, You don't want one speaker pulling in while the other is
pushing out on the same tone, this will cause it to cancel and will be
noticed in the bass regions mostly.

If you're not sure of the polarity, I have always turned on the system
and played something with some bass in it. the correct polarity will yield
the max bass..

I agree with the notion that absolute phase is irrelevant, but one thing to
consider is that if there are other speakers or the speakers in question are
part of a system with a crossover, then you are not just talking about
absolute phase. You could have a situation where the two speakers are out
of phase with others...

Yes, when talking about individual drivers within a system, you have different situations.
Phase between upper and lower drivers will change response and polar patterns.
