Installation, Battery and Charging | Rockford Fosgate 750X, 550X

INSTALLATION

Trunk Mounting

Mounting the amplifier vertically will provide the best cooling of the amplifier.

Mounting the amplifier on the floor of the trunk will work but provides less cooling capability than vertical mounting.

Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended.

Passenger Compartment Mounting

Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you must have at least 1" (2.54cm) of air gap around the amplifier's heatsink.

Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the passenger compartment will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not recommended.

BATTERY AND CHARGING

Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking your alternator and battery condition to ensure that the electrical system has enough capacity to handle the increased load of your stereo system. Stock electrical systems which are in good condition should be able to handle the extra load of any Rockford Fosgate amplifier without problems, although battery and alternator life can be reduced slightly. To maximize the performance of your amplifier, we suggest the use of a heavy duty battery and an energy storage capacitor.

WIRING THE SYSTEM

!CAUTION: If you do not feel comfortable with wiring your new unit, please see your local Authorized Rockford Fosgate Dealer for installation.

!CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury.

CAUTION: Avoid running power wires near the low level input cables, antenna,

!power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system.

1.Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power cables and any high power auto accessories, especially electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time.

2.Prepare the RED wire (power cable) for attachment to the amplifier by stripping 1/2" of insulation from the end of the wire. Insert the bared wire into the B+ terminal and tighten the set screw to secure the cable in place.

NOTE: The B+ cable MUST be fused 18" or less from the vehicle's battery. Install the fuseholder under the hood and prepare the cable ends as stated above. Connections should be water tight.

3.Trim the RED wire (power cable) within 18" of the battery and strip1/2"of insulation from the end of the wire. Cut the wire loop that is attached to the fuseholder in half and splice the fuse into the power line using appropriate inline connectors. Use the section of cable that was trimmed earlier and connect it to the other end of the fuseholder.

4.Strip 1/2" from the battery end of the power cable and crimp a large ring terminal to the cable. Use the ring terminal to connect to the battery positive terminal. DO NOT install the fuse at this time.

550X, 750X specifications

Rockford Fosgate has long been a leader in the audio industry, renowned for its innovative designs and high-quality sound products. The Rockford Fosgate 750X and 550X amplifiers are prime examples of this legacy, delivering superior performance for car audio enthusiasts.

The Rockford Fosgate 750X amplifier is particularly noted for its impressive power output, delivering up to 750 watts of peak power. This makes it ideal for powering larger subwoofers or multiple speaker setups, ensuring that users experience robust bass and clear sound in any vehicle. The amplifier features adjustable gain control, allowing users to fine-tune their system for optimal performance. Additionally, the 750X boasts a built-in variable low-pass crossover, which helps to channel the appropriate frequencies to the subwoofers, enhancing overall sound quality while minimizing distortion.

On the other hand, the Rockford Fosgate 550X amplifier offers a slightly lower power output of 550 watts. This amplifier is perfect for users who require ample power without the need for an overwhelming system. The 550X also includes adjustable gain control and a variable low-pass crossover, allowing for customization to suit individual preferences and vehicle acoustics. Both models are designed with an emphasis on ease of installation, featuring a compact design and high-quality connectors.

One of the standout technologies found in both the 750X and 550X amplifiers is the Class-D amplifier design. This technology not only improves power efficiency but also reduces heat production, making these amplifiers sustainable for long-duration use. Additionally, Rockford Fosgate incorporates their unique Power Line output, which provides reliable signal transmission without significant loss in quality.

Both amplifiers also come equipped with a robust thermal management system to prevent overheating during intense playback. Additionally, built-in circuit protection features ensure that the amplifiers remain safe during operation, offering peace of mind to users.

In summary, the Rockford Fosgate 750X and 550X amplifiers are excellent choices for car audio enthusiasts looking to enhance their sound experience. With impressive power outputs, adjustable controls, and advanced technologies, these amplifiers stand out in the competitive audio market, providing the performance and reliability that Rockford Fosgate is known for. Whether you’re a casual listener or an audio aficionado, these amplifiers are sure to satisfy your sound cravings.
