Hey, so I bought my 03 tibby in february 2020. When I got it, the factory radio worked, but had a mind of its own, it would change stations randomly and cut on and off randomly.. then one day, i got no sound at all. I assumed it was the radio because the digits on the radio screen only showed half (example, all but the Tom of the F, one line of the M missing, bottom and 3 lines of the top of a 9, etc..) just never showed a full digit. So assuming it was bad, I removed it. I just bought a brand new kenwood radio for $80 and a wiring harness.. I am new to audio work in cars, but I’m fairly certain I did everything correctly. I’ve heard things about the factory amp being the issue, is there any advice on what I can do to thoroughly check everything before I remove the backseat to get to the amp?? Any help is appreciated, thanks in advance!!
