I hope i can get some advice on this issue. I have a 92 ex with the premium sound system. i was tired of constantly buying the cassette adapters to listen to my phone music, so I went out and bought this head unit a couple of months ago. I got it because of the price and because it had a built in auxiliary port. https://www.walmart.com/ip/Dual-Ele...th-Built-In-Bluetooth-USB-MP3-Player/54596679 I also bought the wiring adapter that would connect to the head unit and plug straight in to the existing harness. https://www.walmart.com/ip/Scosche-...66001f5-7ad29234-694c83132de5c14b&athena=true after getting all the wires paired up correctly, i powered it up. everything works good except for one issue. the sound coming out of both passenger side speakers (front and rear) is extremely low. I tried fiddling with the radio settings to get the sound to be better, but nothing worked. I even tried taking the radio and adapter harness out and reconnecting the speaker wire pairs one by one to see what the issue could be. what's really weird is when I connected the right front pair only and tested it, sound came out of both the left front and right front speakers. even when i connected the right rear speakers, the same thing happened with sound pouring out of both sides when the left side pairs were not connected. the original issue still remains with the left front and left rear being loud and the right front and right rear being super soft. i even plugged the old head unit back in and went around to each speaker. everything was fine with that head unit. is my new head unit a dud? how can i get the sound to come out of the right side speakers properly?
