Question about Car Audio & Video
I cant figure out how to get the sub light to turn on..with the subs on my pioneer DEH-p4700MP
Did you connect the blue amp turn on lead to the remote input on the amp?
Some headunits have two blue wires. One is for the antenna and the other is for the amp. If you have sound on the radio but not on cd then the wrong blue wire was used. If you can give me som more detail on the wiring I can help you further. You can test to see if the amp remote turn on lead is providing power to the amp with a meter or a light probe. If you are in fact getting power to the remote terminal and to the main power terminal then check the fuse(s) and make sure the drounding terminal is secured well. If you drilled a screw into the body for the ground then you need to scrape the paint from the body where the ground lug is connected. Also could be a relay inside the amp.
Let me know if any of this helps and what you find and I will be glad to assist you further.
