Built for Serious Subwoofer Systems

The CXA1200.1 is a dedicated mono Class-D subwoofer amplifier designed to put substantial power into a single bass channel.

This makes it an excellent match for:

• High-power single subwoofer systems
• Dual-voice-coil subwoofers
• Loaded subwoofer enclosures
• Truck and SUV systems
• High-output daily drivers
• Factory-radio bass upgrades
• Aftermarket head-unit systems
• Street-performance audio builds

If your subwoofer is rated around 1,000–1,200 watts RMS, the CXA1200.1 deserves a serious look.

1,200 Watts RMS at 1 or 2 Ohms

This is one of the most important advantages of the CXA1200.1.

4 Ohms

600W RMS x 1

2 Ohms

1,200W RMS x 1

1 Ohm

1,200W RMS x 1 ±10%

The ability to produce the same rated 1,200 watts at both 1 ohm and 2 ohms gives you considerably more flexibility when selecting your subwoofer and determining its final wired impedance.

Why 1,200 Watts at 2 Ohms Matters

Many mono amplifiers reach their maximum advertised power only when wired to 1 ohm.

The CXA1200.1 is different.

Because it produces 1,200 watts RMS at 2 ohms as well as 1 ohm, customers have more options when choosing their subwoofer configuration.

That can make the amplifier especially attractive for dual-voice-coil subwoofer systems where a 2-ohm final load is preferred.

1-Ohm Stable

The CXA1200.1 remains fully 1-ohm stable, giving you even more flexibility when designing your subwoofer system.

Always calculate the final wired impedance of the subwoofer before connecting it to the amplifier.

The subwoofer's voice-coil configuration and wiring determine the final load presented to the amplifier.

Match Your Subwoofer Correctly

When selecting a subwoofer for the CXA1200.1, pay attention to both RMS power handling and final impedance.

Ideal Applications

1Ω Final Load: Up to 1,200W RMS

2Ω Final Load: Up to 1,200W RMS

4Ω Final Load: Up to 600W RMS

This makes the CXA1200.1 extremely versatile for customers building a high-output system around different subwoofer configurations.

Efficient Class-D Power

The CXA1200.1 uses a Class-D power design, allowing KICKER to deliver substantial subwoofer output while maintaining a relatively compact chassis.

This is especially useful in today's vehicles, where finding room for large amplifiers can be difficult.

The CXA1200.1 gives installers serious power without requiring the footprint of a much larger amplifier.

Add Bass Without Replacing Your Factory Radio

One of the strongest features of the CXA1200.1 is its FIT+™ factory integration technology.

The amplifier can accept:

Low-Level Input: 125mV–5V

High-Level Input: 1V–40V

This allows the CXA1200.1 to integrate with a wide range of factory and aftermarket source units.

For many factory-radio installations, this means you can add a serious subwoofer amplifier without replacing the vehicle's original radio or adding a separate line-output converter.

Up to 40V Speaker-Level Input

Today's factory audio systems can generate much higher speaker-level signal voltages than traditional aftermarket head units.

The CXA1200.1 accepts up to 40 volts of high-level input signal, providing the flexibility needed for many modern factory systems.

This makes the CXA1200.1 particularly attractive for customers who want to keep their factory infotainment system while dramatically improving bass performance.

Variable Low-Pass Crossover

The built-in low-pass crossover is adjustable from:

50Hz–200Hz

with a 12dB/octave slope.

This allows the amplifier to focus on the low-frequency portion of the music while reducing overlap with the vehicle's full-range speakers.

A properly adjusted low-pass filter can also help the subwoofer blend more naturally with the front and rear speakers.

25Hz Subsonic Filter

The CXA1200.1 includes a fixed 25Hz subsonic filter with a 24dB/octave slope.

The purpose of a subsonic filter is to reduce extremely low-frequency content that may cause excessive subwoofer excursion without adding useful audible output.

This can be particularly important when using certain ported enclosures.

KickEQ™ Bass Boost

The CXA1200.1 features KickEQ™ variable bass boost, providing:

0–6dB of boost at 40Hz

This gives the installer additional control over the low-frequency response of the system.

Bass boost should be used carefully. It is not a substitute for a properly designed enclosure or correctly matched subwoofer.

RCA Pass-Through Outputs

The CXA1200.1 provides full-range RCA pass-through outputs.

This allows the source signal to continue to another compatible amplifier.

For example, you can use the CXA1200.1 to power the subwoofer while passing signal to a separate full-range amplifier powering the vehicle's main speakers.

This can help simplify multi-amplifier system layouts.

Optional Remote Bass Control

The CXA1200.1 is compatible with KICKER's CXARC Remote Bass Controller, sold separately.

The remote allows the driver to adjust subwoofer level from the front of the vehicle.

This is particularly convenient when switching between music with different bass levels or when you want quick control over the system's subwoofer output.

Compact Installation

Despite its 1,200-watt output capability, the CXA1200.1 maintains a relatively compact footprint.

The amplifier chassis measures approximately:

12" × 6-3/4" × 2-3/8"

KICKER also includes vertical mounting hardware for alternative installation configurations.

This makes it suitable for:

• Pickup trucks
• SUVs
• Trunks
• Under-seat areas
• Side-panel installations
• Custom amp racks

Always verify the available mounting space before installation.

Built for Daily-Driver Bass

The CXA1200.1 isn't just about the big number on the box.

Its combination of 1,200W RMS output, 1-ohm stability, 2-ohm 1,200W capability, factory integration, built-in crossover controls, and compact design makes it an extremely practical high-power amplifier for everyday systems.

It is powerful enough for serious bass while still being straightforward enough for a professional daily-driver installation.

Installation Recommendations

For a 1,200-watt system, proper installation becomes especially important.

We recommend:

• Properly sized power cable
• Properly sized ground cable
• High-quality fuse and fuse holder
• Short, secure ground connection
• Proper battery connection
• Secure amplifier mounting
• Appropriate speaker wire
• Correct subwoofer impedance
• Correct amplifier gain adjustment
• Proper crossover configuration

Do not select wiring or fuse protection based solely on the amplifier's advertised wattage. Follow KICKER's installation specifications and the requirements of the complete vehicle electrical system.
