This is my Dad's 2007 Honda Fit Sport. I worked for about 4-5 days on the stereo install. My Dad wanted to maintain all the functionality of the Fit, as well as keep the install low key so as not to attract thieves. Of course he also wanted top sound quality so all these requirements had to be met and I think it turned out pretty well. Here is a list of the components used in the install.
Processor: Rockford Fosgate 3Sixty.1
Amplifier: Eclipse XA5000 5-Channel Class-D
Front Speakers: DLS Ultimate UP6 Components
Rear Speakers: DLS Classic 126 Coaxials
Subwoofer: Elemental Designs 11kv.3
Wiring: KnuKonceptz 4 gauge power
Knukonceptz and RF RCAs
Sound Deadening: Raammat BXT and Ensolite throughout
