i have a 91 accord and a few years ago i installed a new head unit and 4 new nice speakers. for years everything sounded fine. for reasons unknown the front 2 do not work at all anymore. i checked the fader button, checked the wires connected to the speakers, and checked the wires comming out of the head unit. sounds crappy with only 2 speakers goin, help/suggestions please!
i would say run some new speaker wire from your speakers directly to your HU. or atleast attach some new wire to your speakers and without rewiring it and hiding them just go straight from your speakers to HU and see if they work.
