Frequently Asked Questions
Do your radios work on 6 volt systems or on positive ground sys-
tems?
No. Our radios are 12 volt, negative ground only. After-market converters
and inverters are available but must provide at least 10 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 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 our 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.
My car originally came with a switch to control my automatic
antenna. Can I use the RetroSound
®
radio’s remote antenna wire to
control my antenna?
No, you cannot. Your factory antenna is known as “semi-automatic.” It
requires a switch to either extend or retract the antenna. You must retain
this switch to control your antenna; the RetroSound® radio’s power
antenna wire is for more modern “fully-automatic” antennas not requiring
a separate switch.
