adjusting Your sYsteM-Please read!
In order to make your new system perform as good as it was designed,
please take a minute to understand and follow these tips:
1) Set your “Automatic Volume Control” (AVC) to 3 bars. After extensive
on-road testing, we found that this AVC position works and sounds best.
Your new amplifier has been specifically set-up for this radio setting.
2) Your Hogtunes system is designed specifically for a motorcycle at speed.
Exhaust noise and wind noise have been taken into careful consideration
in how your system performs. How your new system sounds in a driveway
or garage is radically different from how it will sound at highway speeds.
Although your system was set-up with a factory radio, with its bass and
treble controls in the middle position, if you feel the need to make
adjustments please do so (carefully) at your normal cruising speed.
