How do you connect new 6x9 rear speakers to the factory wiring in a 1990 Mercury Topaz?

First of all you will need to snip the factory connector off near the speaker(s) you intend to replace. Then it is a matter of trial and error to get the correct polarity. If the polarity is reversed, you will still get sound out of the speaker, however, the tone coming out of the speaker will be higher (little to no bass). If that happens, reverse the wires and mount the speakers.

Attach the wiring harness to the back of the new speakers. Secure the speakers into place with the retaining screws. Put the speaker covers on.

The Pontiac Montana does not come with a factory installed amp in the sound system. The wiring goes directly from the radio to the speakers.

it could be as easy as swapping the wires on your speaker to reverse the polarity also there should be proper speaker wire used for wiring speakers but if they are factory fitted this should not be a problem also check your speakers for any sign of damage what you could do as a test is to swap the wiring for the front speakers with the wiring for the rear speakers if the problem moves to the back speakers then its a wiring problem but if the problem is still on the front then its probably the speaker is at fault the beat way to do that test would be to actually move the speakers temporarily rather than moving the wiring
