I've finally finished making a mount for my equalizer which I'm using in place of a head unit. I'll post more info about it in my build thread when I have time. But I'm having this issue now where I'm not getting sound out of the rear speakers. I had the equalizer hooked up some time ago and tested everything and I had sound out of all four speakers. What I've done is I've made a cable which connects to the amplifier's din connector and it has 4 rca, a ground, and the amplifier's remote trigger. I've verified continuity and verified the pinout of the din connector. I've also verified that the speakers have continuity at the amplifier's connector and the resistance is dead on at 3 ohms. I've verified that the equalizer is outputting all 4 channels correctly. If I plug one rca at a time into the same output on the equalizer, I get good sound out of the front right speaker, no sound on the front left (I don't have a speaker connected), and no sound out either rear speaker. When I have just the rear speakers connected to the amplifier, I can hear the sound very quietly on the front right speaker. Does it make sense that both rear outputs on the amplifier would die like that? Does anyone have one of these behind the lower cubby amplifiers laying around that I can buy to help test?
