HELP - Active Sub In Boot (UK 07)
After successfully upgrading the door speakers with guidance from this forum I'm having trouble installing slim active sub in the boot. It's the ground zero GZUB 800ACT active sub similar to the Focal Bus20.
The sub can be fitted using RCA pre-outs with remote wire or high input directly from speakers with auto sensing on/off. I opted for the second as the Business CD unit does not have pre-outs.
I have spliced leads from the rear door speakers to the active sub in the boot. This is fused & connected to the battery terminals including ground. I have verified speaker signal and12v power is present to the harness of the active sub but it still fails to auto switch on when audio is playing.
I'm guessing this is happening because the speaker leads I have extended to the sub are not carrying enough current to trigger the auto sensor on the active sub.
Should I run a remote wire to the sub harness even though it is marked not required in manual?
If so where can I tap 12v for remote wire with greatest ease to the boot?
Is the cigarette lighter in the boot an option? Not sure if it stays on without key.
Anything else I can use in the boot?
I also read instructions from fellow UK member that used violet+white bt/satnav wire at rear car seats for remote. My x3 does not have BT or satnav so I'm not sure if that wire will be available & do not want to pull out the rear cabin to get to them unnecessarily.
