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
have your radio and
am
having problems getting it
to
turn on.
RetroSound radios require 12
volts
to
both
power
I eads. 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
((off"
to
uon".
If
there
is
a significant d rap 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
or
18 gauge
wire
for
the speakers.
If
it
is
a longer
run,
we
recommend using 16 gauge
only.
I
have
a/14
speakers connected
to
your radio and the display
is
lit up like it
is
working
1
but
there
1
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
compatible
with
modern
electronics.
My car originally came with a switch
to
control
my
automatic antenna.
Can
I
use
the
RetroSound radio
1
s remote antenna wire
to
do this?
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.
The
sound output
is
all
mid-range
1
with vety little bass
and
a strangled-
sounding upper range. What is wrong?
One
of
your
speaker wires
is
connected backwards. This
is
called
being
"'out
of
phase." Check
to
make sure positive
is
wired
to
positive and
negative
to
negative on a
II
your
speakers.
