Frequently Asked Questions
The sound output is all mid-range, with very 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 all your speakers.
Will cutting or bending the InfiniMount Brackets void the warranty
or harm the unit?
No. The RetroSound® patented InfiniMount Bracket system has been
designed specifically to be bent, cut and modified to simplify radio
installation. Modifying the radio’s brackets is actually encouraged to
ensure proper fit.
If you have questions about modifying the brackets, contact us via email at

How much should I tighten the shaft nuts when installing the
brackets and mounting the radio to the dash?
DO NOT OVERTIGHTEN
the shaft nuts. The shaft nuts are NOT the
only means of securing the radio to the dash. There is a backstrap
included which works with the shaft nuts to secure the radio to the dash.
Please note that overtightening the shaft nuts could break the shafts.
Retro Manufacturing, LLC will not be responsible for broken shafts due to
overtightening the shaft nuts.
I have your radio with an amplifier connected, but hear a whining/
buzzing sound through the speakers when I step on the accelerator.
If you have an external amplifier installed and experience a high-pitched
noise that varies with the engine’s RPM, there are many possible solu-
tions:
• Make sure the amplifier’s gain controls are not turned all the way
up. Amplifiers amplify everything, including noise.
• Try grounding the amplifier near where it is installed.
• Try a filter on the amplifier’s 12 volt power lead. Make sure to use
a filter that includes a ground wire.
• On rare occasions, noise can be introduced through the antenna lead.
If disconnecting the antenna makes the noise go away, you need to
replace or repair the antenna plug where it goes into the radio.
