I'm installing a little 6" Bazooka powered sub in my 01 9-3. A decade ago I installed it, along with an aftermarket head unit, which included an accessory line, providing 12V to the sub when the head unit was powered on. More recently I put the original stereo back in to work with BlueSaab.
The sub is located in the corner where the CD changer goes, so I was hoping to snag the switched power from the CD changer harness, or the antenna power (not in use since I got my Viggen spoiler from the junkyard
). I learned that both devices have a constant 12v source, even when the car is off. The antenna ground is an open circuit unless it's meant to be running, and I understand the BlueSaab is activated by canbus messages.
Next I spliced into the Antenna Trigger line right from the back of the head unit, as suggested by this guy's SAAB audio site. Unforunately I found that it only has power when on radio.
There is an amplifier trigger line that controls the external amp for the front door speakers. I was recently able to add this amp to my car after another lucky day at the junkyard, but I'm not looking forward to cutting apart the proprietary cable trying to find the wire that goes with the pin.
I'm curious if it would be possible to source the 12v signal from the BlueSaab module. Is there a spot on the board that's got 12v only when the stereo is on, or only when the CD changer is selected?
