Harry, I second Zack - Blank out the stereo and add your own setup.
For what MC charges for the speakers alone, you can get so much more for the money. Example, the new
Fusion tower speakers run around 1k+ for a component speaker setup and $400+ for a 4 light bar. Depending on the dealer, you might be able to get "boat buyer" prices on after-market gear. Also,
Mako has a sweet setup that integrates 4 speakers, 6 lights, and 2 LED pods for the same price as just a couple of MC tower speakers.
If you have any questions, feel free to contact me.
