NVX - XCA9K 9000W RMS XC-Series Competition Class-D Monoblock Amplifier (Strappable & Linkable) – Made in Korea

PowerBass ACS-1000D 1ch Compact Amplifier PowerBass is pleased to introduce their newest series of Class A/B full range and Class D bass amplifiers. Borrowing from their classic ASA series, these new amplifiers offer the most desired features in the most compact chassis allowable. To accomplish this they selected SMD parts and engineered a brand new 6 oz/kg high density heat sink engineered for maximum efficiency and cooling. The result a line-up of two, four and mono channel models that offer great performance and fantastic value. Ultra efficient, the ACS amplifiers produce plenty of low distortion high fidelity audio in a footprint small enough to fit nicely in nearly any vehicle. If you are seeking the perfect mix of performance and value look no further.

NVX XCA6K – 6000W RMS XC-Series Korean Competition Monoblock Amplifier. Built for serious SPL competitors and power-hungry enthusiasts, the NVX XCA6K is a competition-class monoblock amplifier designed for maximum output, reliability, and clean bass. Engineered in the USA and manufactured in Korea, the XCA6K delivers an astonishing 6000W RMS at 1 ohm, making it the go-to choice for elite-level systems.With its strapable and linkable design, this amplifier can be paired with a second unit to output 12000W RMS at 2 ohms, or daisy-chained using the RJ11 synchronization system for massive multi-amp setups—without the hassle of manual gain matching or external processors.The amplifier features Tiffany-style RCA inputs, a wired LED remote bass knob with live voltage and temperature readings, and tuning tools like variable low-pass and subsonic filters. A 91 dB signal-to-noise ratio ensures your bass stays crisp even under maximum load.Internally, the XCA6K is built like a tank, using IRF1404 MOSFETs, 12 FDH45N50F high-current transistors, and 35V/4700µF capacitors for peak power delivery and ripple suppression. With triple 1/0 AWG power and ground inputs, 4 AWG speaker terminals, and 4-way protection circuitry, this amp is engineered to push your system harder, longer, and louder. If you're serious about SPL or simply want the absolute best for your system, the NVX XCA6K delivers the kind of power and reliability few amps can match.

NVX XCA3K – 3000W RMS XC-Series Korean Competition Monoblock Amplifier. Engineered in the USA and made in Korea, the NVX XCA3K is built for serious bassheads and competition enthusiasts. This 1-ohm stable Class-D monoblock amplifier delivers a relentless 3000W RMS of clean power, ideal for high-output SPL systems and demanding subwoofer setups.Whether you're strapping two units for a monstrous 6000W RMS at 2 ohms, or linking multiple amps with the built-in RJ11 synchronization system, the XCA3K ensures unmatched scalability and simplicity—without the usual complexity of external tools and gain-matching hassles.Key features include precision-machined Tiffany RCA inputs, a full suite of audio tuning controls (low-pass, subsonic, gain), and an included LED bass remote that displays voltage, temperature, and clipping in real time.Built using IRF1404 MOSFETs, high-current FDH45N50F transistors, and 35V/4700µF capacitors, this amp is ready to handle intense current demands with stability and minimal heat. Dual 1/0 AWG power inputs and a robust 4-way protection circuit ensure long-term reliability under extreme performance conditions.
