Frequently Asked Questions - CA300P2/24V CALIBER

What is the maximum power output of the Caliber CA300P2/24V?

The maximum power output is 2x 450W at 4Ω in stereo mode, or 1x 1500W at 4Ω in bridged mode, at 24V.

What are the RMS power ratings?

RMS output is 2x 150W at 4Ω in stereo, or 1x 480W at 4Ω in bridged mode, at 24V.

Can I use both RCA and high-level inputs at the same time?

No, you should never use both inputs simultaneously. Choose one or the other.

What fuse rating does the amplifier require?

The amplifier has two 15A fuses (2x15A). Always use the same rating when replacing.

What is the recommended cable size for power and ground connections?

Use a cable of at least 10 mm² for both +24V and ground connections to ensure proper current flow.

How do I adjust the input level to avoid distortion?

Set the input level knob to minimum, turn radio volume to 3/4, then slowly increase the input level until you hear distortion, then reduce slightly. Adjust bass boost after.

What is the warranty period for this amplifier?

If installed by an authorized Caliber dealer, the warranty is 12 months from purchase. If self-installed, the warranty is limited to 30 days.

Does the amplifier have protection features?

Yes, it includes thermal, overload, and short circuit protection, as well as muting circuitry to prevent turn-on/off pops.

What is the frequency response range?

The frequency response is 5Hz to 55kHz, allowing for deep bass and clear highs.

How much clearance does the amplifier need for ventilation?

Allow at least 5 cm (2 inches) of space on all sides for proper heat dissipation.

FEATURES

• Stereo output.
• Pulse Width Modulated (PWM) MOSFET Power Supply.
  • Variable input sensitivity: RCA input 0.2V to 3V.
  • Thermal-, Overload- and Shortcircuit protection.
• Excellent muting circuitry assures no turn on/off 'pops'.
  • Built-in High / Low Pass Filter
  • Gold plated power connectors for optimal power distribution.
  • European design and engineering.
  • Gold plated speaker connectors for optimal signal output.

MOUNTING

The amplifier has to have at least 5 cm (2") ventilation space at all sides, to allow the heat to rise away from the amplifier. Be sure that the power and signal cables can enter and leave the amplifier in a straight line, to avoid the risk of malfunction. Always place the power- and signalcables at opposite sides of the vehicle to reduce any noises.

The amplifier should be protected from exposure to moisture and direct sunlight.

Mark the mounting surface using the amplifier as a template, then drill 2.5 mm (1/8") diameter holes at the marked locations and mount the amplifier using the supplied self-tapping screws.

INSTALLATION

Remember to always disconnect battery ground before working on a vehicle's electrical system! Always place a fuse or circuit breaker no more than 30 cm (12") from the battery, no greater than the fuse(s) of your amplifier for optimal protection.

GETTING YOUR POWER STARTED

• First, the +24V terminal is connected directly to the battery of your car. Use a cable of at least 10 mm ^2 , and make sure that the connectors are of the same value.
• Don't forget the extra "Vehicle protection" fuse.
• The +24V terminal should NOT be connected to the car fuse box.
• Second, the ground terminal (GND) must be fastened securely to the chassis of the vehicle with the same mm ^2 cable as the positive cable (the same amount of power has to run through it). Ensure that all paint, undercoating or any other insulation is removed from the area where you want to make your ground connection to.
• Third, the last cable to connect is your remote turn-on (REM). Many radio-cassette and CD-players have an output terminal for connection of the REM of an amplifier. If you don't have such an output, a separate switch must be installed to control your amplifiers on/off function.

SIGNAL INPUT

The Caliber Amplifiers offer you two possibilities for your signal input.

• A High Level input, using the loudspeaker output from your radio and the special High Level inputplug you found in the box.
• Signal input by using a RCA cable from your radio's RCA outputs to the amplifiers signal input RCA's.

NEVER USE THE HI INPUT AND RCA INPUT AT THE SAME TIME!

RCA INPUT

- Connect the RCA-outputs of your radio to the RCA input terminals of the amplifier. Take good care that you connect the Right output of your radio to a Right input of your amplifier, and that you connect the Left output of your radio to a Left input of your amplifier.

AMPLIFIER ADJUSTMENTS

• Put the input level adjustment knob to the minimum.
• Put the volume of your radio to 3/4 of the maximum.
• Adjust the Bass Boost to your personal sound.
• Now adjust the input level of the front channel. Slowly turn up the input level and listen carefully until you hear the amplifier begin to distort. A Caliber Amplifier "clips" very softly, so this can sometimes be a difficult adjustment. If you have turned up the Bass Boost to much, the amplifier will start clipping immediately. In that case you must turn back the Bass Boost and start adjusting the inputlevel again. You will hear that the Bass you wanted can be required in this way.

CALIBER WARRANTY

Due to the complexity of our products, we strongly recommend that this amplifier is installed by your authorized Caliber dealer. If properly installed by your dealer we provide a warranty for 12 months from the date of purchase. If you install this amplifier yourself, we wish you lots of fun and succes in doing so. If you follow our guidelines, you'll get the best result. Our warranty, however, will be limited to and not exceed 30 days from the date of purchase.
