Overhauling the Camry's Sound System. Currently it's running all factory stuff but I picked up
Polk Audio 660.4 Car Amplifier
Polk Audio DXi 6500 Component System
Polk Audio DXi 690 6x9 Speakers

Only parts I need are:
Liliput Dash Kit for a 2009 Toyota Camry
Replacement M2 Power Supply for CarPC
Toyota Camry Backup Camera

Then a bunch of wiring and so forth to complete the installation.
