Action to Solve
Problem
Check all connections for
proper voltage with a volt
meter. Voltage range:
12-15 volts
Check +12 volt
accessory wire
connection
Check ground
connection
Replace blown fuse
Increase radio volume
Check speaker leads
for any grounded or
shorted wires
Make sure the unit is in the
desired source mode

)
USB 2
Incorrect fuse used, make sure
only fuses with correct 15 amp
ratings are used and check all
wiring connections for
possible short
Make sure battery is properly
connected

FREQUENTLY ASKED QUESTIONS

Do your radios work on 6 volt systems or on positive
ground systems?
No. Our radios are 12 volt, negative ground only. After-market
converters and inverters are available but must have at least 8
amps of continuous output.
I'm having problems getting the radio to turn on.
RetroSound radios require 12 volts to both power leads. The red
®
lead (+12 volt accessory) goes to a switched power source, and
the yellow to a constant +12 volt power source. Using a volt meter,
check the voltage when the key is turned from "off" to "on". If
there is a significant drop in the voltage, the circuit the yellow lead
is attached to cannot handle the additional draw of the radio.
You will need to find another circuit that can handle the additional
draw of the radio, or you will need to go directly to the battery.
What speaker wire do you recommend I use?
We recommend using 16 or 18 gauge wire for the speakers.
If it is a longer run, we recommend using 16 gauge only.
I have all 4 speakers connected to your radio and the display is lit
up like it is working, but there's no sound coming out.
This usually indicates one of two things:
• Speaker wires touching each other or the vehicle chassis at
some point. Check each speaker lead from radio to speaker.
• Speaker impedance below 4 ohms. Older speakers are
usually not compatible with modern electronics.
