Phase II

I'm going to continue experimenting with the sub. I may attempt to build a custom enclosure that fits above the battery compartment like Jim L did for his 540i. It's a sweet solution that doesn't give up any usable trunk space. I may also just go nuts and build a complete system rack with the sub enclosed in it. Using the fold-down rear seats will then require removal of the entire unit, amp and all, but hey - if I'm hauling something that large I can deal without tunes for a short amount of time.

I also need to wire in the AC502 remote sub volume control from the trunk to the front dash somewhere. I'm targeting the switch blank next to the fog light dial. Jim recommends running the cable down the right side of the car and under the carpet to the rear of the dash. I'll report back when I've accomplished this. For now I've got the cable running free from the trunk to the center area up front. I just reach over and adjust the volume when necessary. It looks sloppy and won't suffice for a long-term solution.
