Diamond Audio - NEO12004DSP - 1200W RMS Class D 4-Channel Amplifier - Black/Gray

NVX XCA9K – 9000W RMS XC-Series Korean Competition Monoblock Amplifier. Push your bass system to the absolute limit with the NVX XCA9K — a competition-class monoblock amplifier engineered for maximum performance, durability, and unmatched output. Designed in the USA and precision-built in Korea, the XCA9K delivers a true 9000 watts RMS at 1 ohm, making it ideal for elite SPL systems and hardcore bass enthusiasts.Featuring strapable and linkable architecture, this amplifier can be paired with a second unit for 18000W RMS at 2 ohms, or linked with multiple amps using its built-in RJ11 synchronization system. No complicated tuning or extra tools needed—gain matching is handled internally for effortless expansion. The XCA9K includes a wired LED remote bass knob that shows live voltage and temperature, plus a clip light for real-time safety and tuning feedback. A full suite of audio controls includes a variable low-pass crossover (35–250 Hz) and subsonic filter (10–50 Hz) to help you shape your bass perfectly. A 91 dB signal-to-noise ratio ensures your music stays clean at any volume. Internally, the XCA9K is built for extreme reliability using IRF3206 high-efficiency MOSFETs, 12 FDH45N50F output transistors, and 35V/4700µF capacitors to deliver smooth, consistent power. With triple 1/0 AWG power and ground inputs, 4 AWG speaker terminals, and 4-way protection circuitry, it’s ready for the most demanding installs. If you want the most powerful and reliable amplifier for your competition system or extreme daily setup, the NVX XCA9K is your ultimate solution.

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.

The XL series was developed for the growing Power Sports market including UTV and Marine applications, where electronics must withstand harsh damp environments. The circuit boards have been conformal 5 coated with a layer of transparent material that protects the parts against moisture, dust and extreme temperatures. These ultra small weather resistant amplifiers are ideal for all types of outdoor audio applications such as motor cycles, golf carts and off road vehicles. But the small size also makes these amps a great choice anywhere space is a premium. Utilizing the latest Class D circuit design these amplifiers may be small on size but they are big on power and have a much lower current draw compared to other amplifiers with similar power output. The wrap around aluminum heatsink keeps everything. Extremely versatile, each model gives you're choice of low level RCA input or 3.5mm (1/8") mini-pug Aux Input. The Aux Input allows for easy connection of portable devices such as an iPod, MP3 player or smartphone to become your source unit.
