APX480M Power System Amplifier

INSTALLATION

This section suggests Mounting and Wiring Precautions for installing the Clarion APX480M amplifier. If you do not posses the necessary tools and installation experience, do not attempt to install this amplifier. Instead, con- tact your local Clarion dealer to perform the installation.

MOUNTING PRECAUTIONS

Prior to mounting the amplifier, make sure it is safe to mount the amplifier in that location. Failure to do so can result in serious damage to the boat. In addition, stainless steel hardware should be used to mount the amplifier and additional accessories. When possible, use a nut and bolt with a lock wash- er to secure the amplifier. Extra care and attention is necessary in marine installations due to the uncertainty of water conditions.

Additional precautions and suggestions:

1.For the most efficient cooling, mount the amplifier so cool air runs along the length of the heat sink, rather than across them. To increase air movement and circulation, a cooling fan can be installed.

2.Mount the amplifier on a rigid surface; avoid mounting to subwoofer enclosures or areas prone to vibration.

3.Prior to drilling and holes, make sure the proposed mounting holes will not cut into the fuel tank, fuel lines, electrical wiring, or through the boat.

4.Do not mount the amplifier where it is susceptible to water.

WIRING PRECAUTIONS

Read all of the wiring precautions prior to making any connections. If you are unsure and/or don't have the necessary installation hardware, contact your local Clarion dealer to perform the installation.

1.Before you begin the installation, make sure the source unit Power switch is in the OFF position.

2.Disconnect the negative (-) lead of the battery (or batteries) before making any power connections.

3.When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.

4.A good ground is critical for the performance of the amplifier. A ground wire should be run directly from the battery to the amplifier. Use black insulated 10-gauge or larger wire for the amplifier's ground (-) power lead.

5.Add an additional fuse holder and fuse at the positive (+) terminal of the battery. The fuse rating should equal the total current consumption at full output of the amplifier(s). Use red insulated 10-gauge or larger wire for the amplifier's positive (+) power lead. Do not install the fuse until the complete installation has been performed.

APX480M specifications

The Clarion APX480M is a cutting-edge marine amplifier that combines power with durability, making it an excellent choice for boat enthusiasts who want to enhance their audio experience on the water. This amplifier is designed to deliver high-quality sound and can power even the most demanding marine audio systems.

One of the standout features of the APX480M is its impressive power output. With a maximum output of 480 watts, it can drive multiple speakers and subwoofers effectively, providing a rich sound experience. The amplifier operates at a 4-channel configuration, allowing for diverse installation options. It is capable of delivering 60 watts RMS per channel into 4-ohm loads, ensuring that you can achieve loud and clear audio without distortion, even at higher volumes.

The APX480M is built for the tough marine environment. It has been designed and constructed to resist moisture and corrosion. The amplifier features conformal coated circuit boards, which protect the electronics from harsh marine conditions such as saltwater and humidity, contributing to its longevity and reliability. Additionally, the rugged aluminum heatsink provides efficient thermal management, preventing overheating during extended use.

Another notable characteristic of the APX480M is its built-in high-pass and low-pass crossovers. These allow users to fine-tune their audio system, ensuring that each speaker receives the appropriate frequency range. This feature enhances overall sound quality and helps in achieving a balanced audio experience, essential for listening to music while cruising on the water.

The amplifier also incorporates advanced technologies for improved performance. Some of these technologies include a MOSFET power supply, which maximizes efficiency and minimizes signal loss, and a variable bass boost, allowing users to emphasize low frequencies for a more powerful bass response. It also features low-level RCA inputs, making it easier to connect to head units for seamless integration into existing audio systems.

Installation is made simple with the APX480M, thanks to its compact design and user-friendly layout. The amplifier comes with a comprehensive set of mounting options and a straightforward wiring scheme, making it accessible for both novice and experienced installers.
