So here is what I decided on for audio on my Road King. Put Everything in the left saddle bag and speakers in the lower fairings.

• Polk Audio AA2651-A MM651 Inch Coax Speaker
• Alpine KTP-445U 4 Channel Power Amp (90×2)
• Rockford 10 Awg Power Installation kit RFK10i
• Driver Battery Quick Connect Plug Kit from Driver Recovery Products
• Allstar ALL76268-4 Wire Flat Weather Pack Individual Connector Kit
• Fusion MS-BT100 Bluetooth Dongle for Fusion Marine Stereo Head Units
• JL Audio CL-RLC

So I can now play music via Bluetooth from my Phone or iPod Touch - Just need to decide where to install the JL Audio CL-RLC volume ****.

Here's how I laid out the wiring



Built a false bottom and everything under it



Then I tossed a painted piece of black plexiglass to clean up the look a little



Here's was installed. For the total cost I'm happy with it, I can hear it without a windshield up to about 70 (obviously not crystal clear, but can sing along).
