I have searched everywhere on this site and the web and can’t find the answer to this. I have a Pioneer 4500 Head Unit that like most high-end units, has both speaker and line-level outputs. I want to use the line-out from the HU to power the factory subwoofer amplifier, and use the speaker level outputs to power the rest of the speakers.
By the use of my multimeter, there are two lines of 5 volts out of the factory HU that goes to the factory sub amp. If this is how the sub amp turns on, I can build something to convert 12v power antenna lead from the aftermarket HU to 5v to trick the factory sub amp to turn on. I assume that the other lines are the line-level input to the factory sub amp.
I know there is a lot of info on bypassing the amp, but I don’t want to have to install another amp and run the associated wiring.
Thanks!
