How are your dash speakers connected to the head unit? Did a previous owner wire them directly to the head unit and bypassed the amp? If I recall correctly, the Becker units had both pre-outs (unamplified output signals) and amplified outputs.

The stock set up for the cars with the amplifier had an amp turn on wire. If everything is set up in the stock configuration, turning on the head unit powers the amp on. The signal for the speakers went from the pre-outs to the amplifier and then from the amplifier to the speakers. If the previous owner disconnected the amp turn on wire, the amp won't turn on and power the door speakers. That could be the problem.

The door speakers are not true subwoofers. They are low frequency speakers that average the front and rear outputs.
