Are you certain that you have wired the speakers in phase with each

and with the front speakers?


to be honest - i'm not too clued in on wiring. (or anything else
apparently!) i simply connected the new sony head unit to the existing
din connector - rather than rewire the whole system - this may have
been a bad decision?

Not at all, that's the easiest way to do it. In my new Cavalier, the car was
delivered from the factory with the front left speaker wired out of phase !
I still can't believe it, although I am sure it is an isolated incident.

I would
suggest the problem is that they are a poor match for running off of the
factory deck.

i replaced the factory deck with a sony unit 50wx4, and 4 spanking new
sony speakers, so a matching problem surely cant exist?

Never mind me, I probably didn't catch the beginning of this thread, and did
not realize you had an aftermarket deck.

if the new speakers are over-vibrating and topping out, is that not a
case of too much power getting to them.......or is it the wrong kind
of power?

The deck should not be able to overpower the speakers. Turning the deck up
to very high volume would cause it to send distorted signals to the
speakers, and they would sound horrible, but that should only happen up past
about 3/4 volume.
I suppose it is possible that your expectations were too high as far as how
much better the sony equipment would sound, but without being there it is
hard to say how good it should sound.

feel free to slap me if any of these sounds like forrest gump
questions.

Never, questions are more important then answers sometimes.

gonna bring it to my friendly mechanic/stereo guy to check the wiring
etc, and see what can be done. been looking into the amp and sub
option just in case - any suggestions welcome...
