Taramps TS 400X4 Black 400W RMS 4-Channel Class D Car Audio Amplifier – 2 Ohm Stable, Bridgeable

Example Four-Channel Installation

This configuration works well for many aftermarket coaxial and component speaker systems.

For component speakers, use the manufacturer-supplied passive crossover networks unless your installation uses a properly configured active crossover system.

Always verify speaker impedance and RMS power handling before connecting the amplifier.

Bridgeable Design for Compact Subwoofer Systems

The Taramps TS 400X4 supports bridged operation, allowing compatible channel pairs to deliver up to 200 watts RMS at 4 ohms.

This makes it useful for custom systems that require higher power from fewer amplifier outputs.

Potential applications include compact subwoofer systems, properly matched midbass drivers, and other compatible speaker configurations.

Bridged Installation Considerations

When bridging amplifier channels, the connected speaker load must meet the manufacturer’s minimum bridged impedance.

For the TS 400X4, the specified bridged rating is at 4 ohms.

Do not connect a 2-ohm subwoofer to a bridged channel pair unless the manufacturer explicitly approves that configuration.

Follow the official wiring diagram to identify the correct bridged speaker terminals.

Efficient Class D Amplifier Technology

The Taramps TS 400X4 uses Class D amplification to provide efficient power delivery in a compact design.

Compared with traditional Class A/B amplifiers, Class D technology generally converts a greater percentage of electrical energy into useful audio output rather than waste heat.

This is particularly useful in space-constrained installations such as motorcycles, compact cars, and custom audio enclosures.

Proper ventilation is still necessary, especially when operating the amplifier at high output for extended periods.

Factory Stereo Ready with High-Level Inputs

One of the most useful features of the TS 400X4 is its high-level speaker input system.

Many factory stereos lack dedicated RCA preamp outputs, making traditional amplifier integration more complicated.

The TS 400X4 can accept compatible speaker-level audio signals, allowing many drivers to retain their factory head unit while adding aftermarket amplification.

Benefits of High-Level Inputs

• Keep the original factory stereo.
• Add dedicated amplification to compatible aftermarket speakers.
• Reduce the need for a separate line output converter in supported installations.
• Simplify many factory radio upgrade projects.
• Support automatic amplifier turn-on through the high-level input system.

Factory premium audio systems may still require additional integration hardware.

Automatic Turn-On for Convenient Installation

The TS 400X4 supports automatic turn-on functionality through its high-level input system.

In compatible installations, the amplifier can activate when the factory stereo provides the appropriate signal.

This can simplify wiring by reducing the need for a separate remote turn-on connection.

Always confirm the manufacturer’s installation requirements and compatibility with your particular radio.

RCA Inputs for Aftermarket Head Units

For vehicles equipped with aftermarket stereos, the TS 400X4 also provides RCA line-level inputs.

These allow connection to compatible head units and audio processors.

An aftermarket radio with appropriate RCA outputs can provide a convenient signal source for the amplifier.

For more advanced systems, a compatible digital signal processor can offer additional equalization, crossover control, and speaker tuning.

Built-In HPF, LPF, and Full-Range Crossover Modes

The Taramps TS 400X4 includes selectable crossover modes designed to support different speaker applications.

High-Pass Filter (HPF)

High-pass filtering reduces low-frequency content sent to connected speakers.

This is useful for compatible door speakers and midrange drivers that should not reproduce deep bass.

Low-Pass Filter (LPF)

Low-pass filtering reduces higher-frequency content.

This mode can be useful for compatible compact subwoofers and dedicated low-frequency speakers.

Full-Range Mode

Full-range operation allows the amplifier to reproduce its supported audio range without applying the selected onboard high-pass or low-pass filter.

This is useful when appropriate external crossovers or digital signal processing handle frequency management.

Important: The supplied product information does not specify the exact onboard crossover cutoff frequencies. Verify those specifications before designing an active speaker system.

Tweeters must always receive suitable high-pass filtering, either through a correctly configured active crossover or a manufacturer-approved passive crossover network.

Ideal for Motorcycle and Powersports Audio Builds

The compact design and efficient Class D architecture make the TS 400X4 an attractive option for custom powersports audio installations.

Potential applications include:

• Motorcycle speaker systems
• ATV and UTV audio upgrades
• Golf cart sound systems
• Custom trunk audio installations
• Compact car and truck stereo upgrades
• SUV aftermarket speaker systems
• Protected marine audio installations

Important Powersports and Marine Considerations

The TS 400X4 is not identified in the supplied specifications as waterproof or marine-certified.

For motorcycles, boats, ATVs, and other vehicles exposed to water or severe environmental conditions, install the amplifier in a suitably protected enclosure or location.

Verify electrical compatibility, charging-system capacity, vibration resistance, and environmental protection before installation.

Compact Black Chassis for Custom Installations

The Taramps TS 400X4 features a compact black amplifier housing designed for flexible mounting.

Its space-conscious construction makes it useful in vehicles where larger amplifiers may be difficult to accommodate.

Potential mounting locations include protected under-seat areas, custom amplifier racks, and properly ventilated storage compartments.

Always measure available space and confirm the amplifier’s exact dimensions before purchasing.

Avoid mounting the amplifier where it may be exposed to water, excessive heat, or physical damage.
