I started with an Out of Sight audio Mark 1 Bluetooth stereo system. It is a small (6”x4”x1”) 75 watt per channel (X 2) stereo receiver. It is not hooked up to any radio or other stereo unit. It is hidden in my console and is not necessary to access after install. Unit is grounded to bottom of metal console. I ran a 16 gauge red wire from battery positive to a LED lighted switch on dash through a 15 amp fuse. The wire then continues to unit. The unit remains off until you throw the switch on the dash. I used an existing 1/2” diameter cutout that was already in dash for the switch. I used an LED so my wife would not forget and leave the unit on when not in use. I considered using the ignition ACC switch as an option, but decided to go with dash switch so unit could be instantly turn on or off. The two (max number) speakers are Bose 161 bookshelf speakers. They had the right Ohm impedance for the unit. The two speakers are simply zip tied to the rollbar behind front seats.
The Bluetooth system works great. After your device locates the “OOSA”, it pairs quickly and starts playing your tunes. Volume is controlled through device. When first powered on, the volume starts out at a lower level, not on max , even if your device is on max volume before starting. The system will only recognize one device at a time, and a device must be unpaired or not on range before another device can be paired. My device remembers OOSA and pairs quickly after throwing switch.
I added a USB charger to bottom of console that can handle two charging cords.
