Introduction
Thank you for your purchase of a Custom Autosound radio.
This AM/FM receiver is specifically designed and manufactured for your classic vehicle.
It is a reflection of over 36 years of customer feedback regarding preferred features,
vehicle compatibility, cosmetics and quality components.
The quality of the components and various parts that are used in our radios were devel-
oped in a California audio research laboratory. The laboratory researched and assem-
bled the finest affordable CD controller radio tuner and amplifier sections.
Custom Autosound and its staff own over 16 classic special interest cars and trucks.
These vehicles are used for research and development, car shows meets and much
personal pleasure. We find that our custom radios only sound as good as the speakers
they are matched with and a quality installation.
We also manufacture a full line of rear, dual front and dual voice coil speaker assem-
blies to fit in the original speaker areas. Also available are replacement kick panels with
built in speakers and a custom 2.1 amplified system with satellite speakers that look
like AC vents. All of these speaker assemblies are made to be mounted without perma-
nent vehicle modifications. Check out our web site!
Your Custom Autosound authorized dealer has information regarding our speakers and
special speaker assemblies, as well as information regarding custom radios for vehicles
other than yours. We offer over 300 different ‘conversions’ for various makes, year
groups, all radios are ready to install, no assembly required.
Again, we thank you for your purchase! You have increased the value and "Driving
Pleasure" of your classic without compromising originality.

static interference.
NOTE: Do not use spark plug or distributor noise filters as these can create more
problems than they can solve. They decrease the quality of the spark generated by
the spark plugs and they may create more static than they eliminate.
Accessory Noise
A popping heard when the lights, turn indicators, windshield wipers, cigarette lighter,
etc. are switched on indicate a vehicle wiring deficiency. Most occurrences are
minor and preset no risk to the stereo system other than the annoyance to the lis-
tener. However, severe cases may damage the speakers, minor occurrences can be
remedied. A professional must attend to severe occurrences, as they present a
threat to not only the stereo system but to the vehicle wiring itself.

should be rated at a minimum of 3 amps.
