Rockford Fosgate DSR1 User Manual

This DSR1 Is Pre-programed for
You.
All DSR1s that we ship are programed for ‘14 through ‘18 Harley Infotainment radios that only have the front channels enabled. If
you have a ‘19 or newer Harley with a GTS radio you will need to download our DSR1 setup file for the GTS radio. If you do not
have a factory radio simply hit the EQ reset button in the EQ section of the DSR1 app to set the EQ to flat. Then make what
adjustments you need. Other radio configurations like Ultra, CVO, etc. with four or more speakers will need alterations to the EQ
curve that we have set for you. The tune that we put on the DSR1 is free of charge and not guaranteed to be exactly what you need
for your particular situation. User/installer adjustments are required when using a DSR1. You are responsible for all adjustments in
your new audio system. Read the extensive information here and the articles we have published on our website and get to know
what adjustments are needed for your system.
● We have already updated to the latest firmware so there is no need to connect to your computer.
● This DSR1 is already setup for a typical install on a ‘14 & up Harley Davidson with a factory radio with 2 channel input
(front only). Therefore you will not need to go through the setup menu in the Perfect Tune app. The only reason to go
through the setup menu is if your system is not a ‘14 & up with factory radio and/or you are feeding the DSR1 with more
than just the front channels
● Use the “Basic Tune” EQ in the DSR1 app unless you know what you are doing in the “Advanced Tune” section. You
can find several articles about using the advanced tune at
https://www.americanhardbag.com/pages/installation-guides .
● Understand how the “Remote In & Remote Out” connections should be made before you install your DSR1. Improper
connection of the remote in/out can void your warranty.
