HOW TO TROUBLE SHOOT A SYSTEM

GENERAL

A car stereo system consists of many different pieces of equipment connected together, and a logical process of elimination will find the problem area, by isolating sections, and checking them one at a time. Before following the instructions below, check and double check all wiring and connections.

TOOLS NEEDED

The following tools will help in finding problems:

A general purpose multi meter, capable of checking voltage and resistance, is perhaps the most useful piece of test gear that any installer can own.

You may also need a test speaker, and a head unit, as these will be handy for temporary connection for checking purposes when you are working in the trunk of the vehicle.

NO SOUND

This is probably the most perplexing problem to find.

1.Reduce the amp gain to 9 volts and unplug the RCA cables and speakers from the amplifier.

2.Check with your multi meter that each amplifier in the system has proper 12 volt DC supply on it’s power terminals.

3.Also check that the remote turn on terminal has 12 volt on it.

If all seems well, and the amplifier power indicators light up without any diagnostic light:

4.Connect the head unit RCA directly to the amplifier (eliminating any signal processors which you may have installed in between the head unit and amplifier) and turn on the system.

If the power LED is on with no Diagnostic LED continue:

5. Connect each speaker one at a time to see which speaker puts the amp in diagnostic.

By utilizing this process of elimination you can determine where the cause of the problem is. If the amplifier goes in to diagnostic with nothing connected to it, and you are sure of proper power and ground, please contact our service department for further help ay 732 370 5400.

Boom

Harder!

AMPLIFIER OVERHEATING AND SHUTTING DOWN

The most common cause for this problem is when amplifiers are overloaded with speaker impedances lower than what they are rated for. Double-check the impedance of your speakers and their wiring. Also check that no speaker leads are shorted to the vehicle metal chassis.

AMPLIFIER GOING INTO PROTECTION

When an amplifier goes into protection mode, we have to first establish whether the problem lies with the amplifier, or whether it is something in the installation. Disconnect all RCA and speaker cables, leaving the power, ground and remote connections. Turn the system on, and if the amplifier now powers up properly, add the RCA cables, and see if the amplifier goes into protection. If not, proceed by reconnecting the speaker leads, etc. By following this simple process of elimination, the fault can be diagnosed quite easily.

LACK OF BASS

The lack of bass can be attributed to various causes.

Check that the proper recommended enclosures have been used for the woofers.

Check the phasing of multiple woofers connected to one amplifier, as well as those connected to multiple amplifiers. Refer to pages 10, 11 and 12. If the positive and negative terminals are reversed in a two woofer system, you will get a cancellation which sounds like a lack of bass. Always double check your wiring for proper phase.

Position of woofer enclosures in the vehicle will also affect bass output. You should experiment with different box positions, firing forward, backward or upwards to see which way you get more bass in to the cabin.

MONO CLASS D specifications

Cadence Mono Class D amplifiers represent a significant advancement in audio amplification technology, designed to deliver high-quality sound while maintaining efficiency and compact size. These amplifiers are known for their ability to generate substantial power output with minimal heat generation, making them an ideal choice for various audio applications, from home theaters to professional sound systems.

One of the main features of the Cadence Mono Class D amps is their high power output capability. Utilizing a highly efficient switching power supply, these amplifiers can deliver substantial wattage to drive large speakers without distortion, providing a clean and powerful audio experience. This efficiency also translates into lower power consumption, making them environmentally friendly and cost-effective.

Another key technology integrated into Cadence Mono Class D amplifiers is pulse-width modulation (PWM). This technology enables precise control of the output signal, improving sound quality and reducing noise. The PWM technique allows for a more linear amplification process, resulting in better overall performance and fidelity. Users can expect clear highs, punchy mids, and deep, resonant bass that enhances the listening experience.

The robust construction of Cadence Mono Class D amplifiers is also noteworthy. Built with premium components and a durable chassis, these amplifiers are designed to withstand the rigors of both mobile and stationary use. Additionally, features such as built-in thermal protection and short circuit protection ensure longevity and reliability in various operating conditions.

Cadence Mono Class D amplifiers offer flexible connectivity options, including RCA and speaker-level inputs, making them compatible with a wide range of audio sources and systems. This versatility allows users to integrate the amplifier seamlessly into their existing setups without the need for complex configurations.

The compact form factor of these amplifiers makes them easy to install in tight spaces, a critical consideration for both car audio systems and home installations. Despite their small size, Cadence Mono Class D amplifiers deliver exceptional performance that rivals larger, more traditional amplifiers.

In summary, Cadence Mono Class D amplifiers combine advanced technologies, robust construction, and efficient design to provide powerful and high-quality audio amplification. With features such as high power output, PWM technology, flexible connectivity, and compact size, they are an excellent choice for audiophiles and casual listeners alike looking to elevate their sound experience.
