92 Ford Explorer JBL Sound System - Sound from door speakers. No sound from Sub. Removed rear wheel panel - checked connections. I'm looking for suggestions on diagnosing the problem. Do I start in the back around the sub or up at the head unit? Any harness that I could check voltages on? Etc. I'm stumped on how to debug this. Would like to debug the existing unit before upgrading. Thanks!
