I did a search but couldn't find a direct answer, so I figured I would ask. I have a '98 base Boxster with dash and door speakers. It originally came with a Becker CDR210, but I was given a Becker CDR220, so added that and a bluetooth module via the AUX/CD Changer. I also have the Nokia 4x40 Watt amp. The dash speakers were shot, so I replaced them and installed them today. They sound much better but there is no sound coming out of either door speaker (which I believe are subs). I believe the wiring is stock and the dash and door speakers are wired to the amp in the front trunk. There is no connector plugged into the head unit amp. I made sure all connectors are solidly plugged in the HU and the amp and it looks like the line out from the HU has a common ground. I find it weird that neither door speaker is working.
- What is the best way to debug this?
- Is there a common failure for the wiring to the door speakers?
- Are the rubber boots at the door hinge a boot or also a connector?
I know the general response will be to simply replace the door speakers but I want to get them working to see where I am before I take the next step.
