Frequently Asked Questions
Do your radios work on 6 volt systems or on posive ground systems?
No. Our radios are 12 volt, negave ground only. Aer-market converters and
inverters are available, but must have at least 8 amps of connuous output.
I have your radio and am having problems geng it to turn on.
RetroSound radios require 12 volts to both power leads. The red lead (+12V
accessory) goes to a switched power source, and the yellow to constant 12 volt
(+12 V) power source. Using a volt meter, check the voltage when the key is
turned from “o” to “on”. If there is a signicant drop in the voltage, the circuit
to which you have the yellow lead aached cannot handle the addional draw
of the radio. You will need to nd another circuit that can handle the addional
draw of the radio, or you will need to go directly to the baery.
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:
1. Speaker wires touching each other or the vehicle chassis at some point.
Check each speaker lead from radio to speaker.
2. Speaker impedance below 4 Ohms. Older speakers are usually not compat-
ible with modern electronics.
My car originally came with a switch to control my automac antenna. Can I
use the RetroSound radio’s remote antenna wire to do this?
No you cannot, your factory antenna is known as “semi-automac.” 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-automac” antennas not requiring a separate switch.
The sound output is all mid-range, with very lile bass and a strangled-sound-
ing upper range. What is wrong?
One of your speaker wires is connected backwards. This is called being “out of
phase.” Check to make sure posive is wired to posive and negave to nega-
ve on all your speakers.
