This is my new project car, a 2006 Chrysler PT Cruiser.
I have just begun the modifications, but as of now the list includes:
--17 inch Vision Rims wrapped in Kuhmo Ecsta Performance Tires

--7 inch fully motorized Jensen 9312 flip-out touchscreen DVD player (New for 2007)

--15 inch Cadence 'Beast' Subwoofer rated at 1300 Watts housed in a standard hatchback box. (About to be installed)

--1600 Watt Audiobahn Chromed out Amplifier
I plan on getting a set of Cadence ZX Component Speakers to finish out the audio...and then on to the engine when I get bored.
Pictures of the system installation will be uploaded soon, Thanks for looking!
