Hi guys,
I've got 4 door speakers (1 in each door) as well as a pair of hat-shelf speakers in my 740. The hat-shelf speakers are connected in parallel to the rear door speakers, and all 6 speakers are currently powered by a 4 x 40W amp.
Anyway I'm planning to add a separate amp to power the hat-shelf speakers, with a fader control to adjust the output balance between rear door speakers and hat shelf speakers. I need to know which wires on the DIN cable that runs from radio to amp are for what, so I can connect the fader switch to the appropriate wires. Has anyone ever tried this? _________________ Will '90 Volvo 744 GLT B230F converted to B230FB (531 Head & VX3 Cam)
