So I just replaced my old 4 channel amp with a newer one (JBL GTO 75.4ii). Now, for some odd reason, I can NOT get more than 1 channel/speaker to work on this new amp. It's either channel 1 or channel 2 but NOT both (FRONT rca's but can't get both speaker channels to play at the same time). Anyone know why this would happen (in general)? I don't think it's my wiring because when hooking the old 4 channel up, everything works as it should. Any thoughts? This is the 2nd 4 channel amp I've tested and have had this happen with.
BTW all my rca's are coming off my IMPRINT (PXA-H100) unit. I did disconnect the power to reset it but it didn't help. Would I need to disconnect my HU power too? Also, would I need to disconnect the AUX cable from the IMPRINT as well? Should I switch the setting from FRONT/REAR/SUB to 3way??
