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 10
amps of continuous output.
I’m having problems getting the radio to turn on.

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 co12 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 to which you
have the yellow lead attached 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 gauge wire for the speakers.
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.
