INSTALLATION
Experience has proven that only technically inclined users who
have the proper tools and mechanical ability should attempt to
install the unit themselves.
If you do not feel confident or if you have an unusual installation
situation, have the unit professionally installed.
IMPORTANT: To prevent alternator and ignition noise pickup,
the power and ground connections MUST be wired exactly as
indicated in the Power and Ground Sections on pages 3 and 4.
Do not run the ground connection direct to the battery.
MOUNTING
The PR-250 IIR comes in two parts. The preamp equalizer is
miniaturized so it can be mounted underdash or in dash and not
lookout of place. The power amplifier is intended to be mounted
where it is out of sight. When considering locations for mounting
the power amplifier, keep in mind that it dissipates a considerable
amount of heat and must be mounted horizontally.
Never mount in a confined area or with the heatsinks directly
against any other surface, since this will cause damage to the
unit from excessive temperatures.
NOTE: Units that fail when improperly mounted will not be
repaired under warranty.
After the desired mounting locations have been found, mount
with the
#8 sheet metal screws
provided.
SPEAKER MOUNTING
The speakers you select and the way you install them will
determine to a great extent how the system will sound. The
Punch has a considerable amount of low frequency boost
available and even fairly small diameter speakers will sound
good. However, the larger the diameter, the greater the power
that can be produced in the low bass range. Where possible use
6” x 9” or 8” round speakers or larger. It’s very important to use
speakers with a wattage rating large enough to prevent speaker
damage (50 watts RMS is recommended).
