I've got an aluminum panel on my D2's rear cargo door. Since I don't have the Subwoofer installed I'm thinking of doing a custom air pump install.

I can route 12v super easy to the door, and I plan on installing the pump on the backside of the panel with rubber bushings to keep the vibration down, then redo the wiring and put an On/Off switch on the aluminum panel, and then have an airline quick disconnect installed on the aluminum panel so I can quickly install/remove one of those 50ft coil air line hoses. It would be out of the way and a nicely custom install.

The ARB pump or something similar should be able to fit in the space inside the door.

Although I removed SLS from my 99 D2 I kept all the hardware.

 

That sounds like a great setup! I'm probably just going to put an airpump on the passenger side firewall.

 

Where did you find the air pump rebuild kit?

 

Most aftermarket dealers sell them but try here:

Be very careful which way up you fit the piston ring or you'll end up with zero compression. XR8 seem to do a good download and vid.
