NVX XCA9K Competition-Class Monoblock Amplifier | Extreme Power & Performance

NVX XCA9K – Competition-Class Monoblock Amplifier

Unmatched Power for Competition-Level Performance

The NVX XCA9K is a competition-class monoblock amplifier designed for extreme power and precision. Designed in the USA and made in Korea, this amplifier delivers 9000W RMS at 1 ohm with ultra-low distortion, ensuring clean, thunderous bass. Whether you're competing or just want unmatched power in your system, this amp is built to perform.

Extreme Power

1 Ohm Stable Monoblock: 9000W RMS for earth-shaking bass.
Strappable: Sync both amplifiers to achieve an impressive 18000W RMS at 2 ohms.
Linkable: Link two or more amplifiers together for enhanced power and performance and run each down to 1 ohm. (All settings controlled from the master amplifier)

Precision Audio Tuning

Variable Low-Pass Crossover: Adjustable 35Hz - 250Hz for precise sound control.
Subsonic Filter: 10Hz - 50Hz to eliminate unwanted low frequencies.
Signal-to-Noise Ratio: 91dB for crystal-clear audio output.

Built for Reliability & Durability

The NVX XCA9K is engineered with precision-machined Tiffany RCA inputs, a 4-way protection circuit, and MOSFET power supplies for stable voltage control. Its heavy-duty aluminum heatsink ensures maximum cooling efficiency.

Advanced Multi-Amp Synchronization

Unlike most amplifiers that require tedious gain matching and expensive tools when strapping or linking, the NVX XCA9K simplifies the process with advanced synchronization technology. This amplifier features a built-in line driver that compensates for signal loss, allowing effortless amplifier linking.

True Plug & Play Linking: Strap two amplifiers together or link multiple units with no hassle.
Precision Gain Matching: Built-in circuitry eliminates the need for external tools.
RJ11 Synchronization System: Ensures consistent signal distribution across multiple amps.

Whether you’re a beginner or a seasoned pro, the XCA9K makes linking multiple amplifiers effortless, removing the complexity of traditional strapping methods.

Upgrade to NVX XCA9K Today

For serious bassheads and competition enthusiasts, the NVX XCA9K delivers unmatched power, efficiency, and reliability. If you're looking for an amplifier that can handle extreme power loads without breaking a sweat, this is your ultimate choice.

NVX XCA9K Owner's Manual

Frequently Asked Questions (FAQ)

What makes XC-series amplifiers stand out among all NVX amplifiers?

XC-series amplifiers are NVX's premium line of Korean amplifiers. These are built for elite competitions and extreme applications, exceeding limits with their earth-shattering power, unparalleled efficiency and industry-leading precision.

What's so special about Korean amplifiers? How are these amps leagues better than typical amps?

Korean amplifiers frequently emphasize high damping factors and robust output stages, allowing better control of speaker drivers and stable operation with low-impedance or difficult speaker loads.

Can I use the XCA9K for competition use at 0.5-ohms?

Competitors do it, but it can be demanding if not dangerous to your vehicle's electric system. For daily use that lasts long, stick to power at 1-ohms as this still hits really hard.

Where should I install the bass remote included with the XCA936K?

You can install the bass remote on the dash or under dash. Just make sure that the cable covers enough distance between the remote and the amplifier.

Why does XCA9K's bass knob have a voltmeter?

Amplifier bass knob generally helps you set the right gain, but XCA9K's bass knob also lets you monitor your electrical health in real-time. If you see it dip below 12V, it’s the solution for knowing when to turn it down before you damage gear.

Why does XCA9K have 3 power and ground inputs? Can I only use one of these?

XCA9K is designed with triple 1/0-gauge power and ground inputs. You must use all of these, as trying to run this 9000W beast through one wire is a fire hazard. Use high-quality OFC 1/0-gauge wire for all six inputs.

I am planning to buy XCA9K and strap it with another competition amplifier. Would that work?

No, you shouldn’t strap XCA9K to a different amplifier model. It will cause mismatch in sound quality and gain matching failure. It’s best to strap the same two amps. We recommend buying two XCA9Ks to achieve 18000W RMS of daisy-chained bass power.

Why did the XCA9K go into 'protect' mode when the bass dropped?

Voltage drop is the suspect. If your car drops below 9.5V, the amp quits to save itself. Upgrading your alternator is the pro solution to keep the power flowing during massive 30Hz notes.

Do I need a second battery for the XCA9K?

Yes. At 9000W RMS, your stock battery is outmatched. Adding an AGM or Lithium bank in the trunk is the solution to voltage drop, ensuring your bass stays consistent and your electronics don't struggle.

Can I use this amplifier in a standard sized trunk?

XCA9K is a huge amplifier at 21.75" long. Measure the space first. It requires a really solid mounting surface to handle the weight and potential pressure.

No way! A korean board from nvx!

Holy God I can't believe I got up this morning & saw this on ebay! Went right to the sonic electronics website to get the dimensions...21.75" long? & it weighs 60lbs? I'm on it. Nvx has always made quality amplifiers, but this is unreal that they're dropping a Korean board now... let's go!
