Thanks to the design of the Bonneville's front windows, there is a huge cavity in my doors to fill with pretty much and speaker I want. I fabbed up a 3/4" MDF speaker baffle and bolted it into the door with carriage bolts.
Speaker wire ran through door on the left (~7" depth). Speaker baffle installed on the right.
The mess in the trunk. (Sony XM-475GSX = temporary amp until Xenon arrived.)
