Posted By: djh0002002 Date Posted: December 04, 2014 at 8:15 AM I CAN SEE ALL THE SPEAKER WIRES ON THE AMP'S 30 PIN PLUS IN THE REAR TRUNK OF THE CAR. PROBLEM IS, I HAVE AN ALPINE PXA-H800 WITH 6 INPUTS AND 8 OUTPUTS, BUT I HAVE 2 DASH, 1 CENTER, 2 FRONT DOOR, 4 REAR DOOR, 1 SUB = 10 SPEAKER OUTPUTS FROM THE AMP. SHOULD I JUST LEAVE THE TWEETS ON THE STOCK AMP AND RUN THE OTHERS THROUGH THE ALPINE CONVERTER (AND OBVIOUSLY TO AN AMP, ETC.)
MY OTHER QUESTION/PROBLEM IS... THERE ARE 4 OR 6 WIRES ON THE PLUG BEFORE THE SPEAKER WIRES. I'M ASSUMING POWER, INTERRUPTS, OR SOMETHING. WHAT ARE THESE? FINALLY, IF I'M RUNNING THE WIRES OUT OF THE STOCK AMP, THROUGH THE PXA-H800, THEN TO AMPS, THEN TO SPEAKERS... AM I GOING TO STILL GET CELL PHONE SOUND AND NAV INTERRUPTS? OR IS THIS THROUGH ANOTHER SPEAKER IN THE CAR? tHANKS FOR ANY INPUT ANYONE HAS. Posted By: jayesco Date Posted: January 27, 2016 at 3:27 PM Does anyone know what color wire from the stock amp to you use for the remote source to aftermarket amp?
