INSTALLATION
BATTERY VOLTAGE:
Cadence Momentum CSA amplifiers are rated and regulated to 14.4 volts and below.
Maximum input voltage is 16 volts while the minimum voltage is 12 volts.
*** DO NOT EXCEED 16 INPUT VOLTAGE. ***
PROTECTION CIRCUITRY:
Cadence amplifiers incorporate many outstanding protection circuits to help protect the
amplifier from being damaged during operating conditions.
Thermal Protection : When the amplifier reaches an unsafe operating temperature of 80
degrees Celsius the amplifier will turn off. Once the amplifier cools down, simply reset
the amplifier by its Remote connection, (turn the amplifier off and then on again once
you have given the amplifier a chance to cool down) and the amp will once again begin
to play.
If you live in a hot climate we suggest installing additional cooling fans in your trunk to
exhaust the hot air which can build up in the trunk this will help keep the ambient temperature
in the trunk as low as possible so that your amps work flawlessly and without any
musical interruption.
Clipping or total shutdown may also be a result of a bad ground connection or loose
ground. If you find that your speakers and speaker wires are not shorted, please check
your ground connection.
Input Overload Protection:
This circuit will either shutdown the amplifier completely or
make the amplifier spurt on and off indicating that it is in a diagnostic condition. Turn
the system off and reduce the gain on the amplifier or volume from your head unit, this
should result in a corrected condition.
DC Offset Protection: Should any DC voltage try to enter the amplifier via the speaker
terminals it will cause the amplifier to shut down and not operate until this condition is
remedied. This circuit will also protect damaging high DC voltages from reaching your
speakers should your amplifier ever malfunction.
INSTALLATION BASICS:
Before you begin with your installation, disconnect the NEGATIVE (-) terminal from
your car’s battery. This safety precaution will avoid possible short circuits while wiring
your amplifier. Cadence amplifiers operate on 12-volt negative ground systems only.
It is recommend that you layout your sound system design on paper first. This will help
you during the installation so that you will have a wiring flow chart and not miss-wire any
of your components.
Mount the amplifier in the trunk or hatch area of your vehicle. Never install an amplifier
in the engine compartment or on the fire wall. Please be sure to leave breathing room
around the amplifier heat sink so that it can dissipate the heat it produces efficiently.
The amplifier can be installed either horizontally or vertically.
When mounting the amplifier on the trunk floor, be sure to watch for your gas tank,
gas lines and electrical lines. Do not drill or mount any screws where they might
penetrate the gas tank of your car.
REMOTE TURN ON CONNECTION:
The remote turn on connection is located on the barrier strip next to the power and
ground connections. This connection is responsible for turning the amplifier on
and off with the rest of the system. A smaller gauge wire can be used to make this
connection to your radio’s power antenna lead. Should your system not have any
turn on leads, you can wire the remote terminal to an accessory lead, which turns on,
with your cars ignition.
POWER/GROUND WIRING:
The Momentum CSA series amplifiers are supplied with built-in fuses, never replace
the fuse that the amp came with, with one of a larger value.
We suggest you construct a Red wiring harness with 2 additional fuses. One fuse
should be located near the car battery. This fuse near the battery offers protection
against damage from short circuits to the car chassis between the battery and the
amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier
itself. This fused red power wire should be attached to the amplifier power terminal
marked +12V .
