Alpine KTA-450 4-Channel 200 Watt RMS Power Pack Amplifier Dynamic Peak Power (DPP) Technology The KTA-450 features Alpine’s exclusive DPP technology, which automatically adjusts the gain to meet musical needs. DPP prevents the amplifier from clipping music signals by supplying up to double the power to support rhythmic instruments that provide snappy sounds (like a snare drum, trumpet, or high-hat cymbals). During these dynamic musical passages, DPP instantly delivers bursts of power to rise to the peak demands of the music. The DPP technology enhances the KTA-450’s performance to 400 watts, essentially doubling the amplifier’s power without increasing its size. Other Power Pack amplifiers featuring DPP technology include the KTA-30FW and KTA-30MW.

Power Acoustik RZ4-2000DSP 2000W 4-Channel Max Amplifier Delivering consistent 2,000 watts of Class D power across four channels, the Power Acoustik RZ4-2000DSPB is engineered for serious car audio configurations. Built for enthusiasts who require clarity and control, this amplifier combines full-range amplification with a built-in Digital Signal Processor (DSP) that offers detailed customization without the need for external processing gear. The compact chassis (4.75” W x 11” L x 1.625” H) fits easily into tight installations without compromising output. Internally, military-grade SMT PCBs and IR™ audiophile-grade transistors ensure thermal stability and signal integrity across all driving conditions. A die-cast aluminum heatsink ensures effective heat dissipation, thereby preserving lifespan and performance. The RZ4-2000DSPB supports precise tuning via SigmaStudio™ software, accessible through Bluetooth or USB. Compatible with Android, iOS, and Windows, this software enables complete DSP control—from time alignment and crossover settings to a per-channel 10-band EQ with adjustable Q factors. You can adjust high-pass, low-pass, and band-pass filters with slopes ranging from 6 to 48 dB per octave and apply a time delay in 0.05 ms increments up to 20 ms. For OEM integrations, the built-in high-level inputs with signal-sensing turn-on eliminate the need for a remote wire, making installation seamless even with factory head units. RCA low-level inputs (200 mV–6V) and pass-through outputs provide flexibility when connecting subwoofer amps or expanding the system design. Performance is backed by stable operation down to 2 ohms in stereo or 4 ohms bridged, with comprehensive protection circuitry against thermal, short, and overload conditions. A bass boost circuit with a 12 dB gain and full crossover controls adds punch without distortion. Whether you're configuring a front-stage upgrade or a full multi-channel system, the RZ4-2000DSPB provides scalable power, deep DSP control, and a platform that integrates cleanly with both modern and legacy vehicle audio systems. General Features: RMS Power: 190W x 4 @ 4Ω, 250W x 4 @ 2Ω, 500W x 2 @ 4Ω bridged Digital Signal Processing with per-channel controls SigmaStudio™ interface with app support 10-band EQ with ±20 dB boost/cut High-level auto turn-on with signal sensing MOSFET power supply and high-current components Protection circuits: thermal, overload, short Frequency range: 20 Hz–20 kHz Ideal For: DSP amplifier setups with full-channel tuning Power Acoustik 4-channel system expansions Factory and aftermarket head unit integrations 2000-watt car amplifier applications with space limitations Included: RZ4-2000DSPB amplifier User manual with DSP setup guide DSP software (available on the Support tab) For installers and builders needing complete DSP flexibility with robust power output, the RZ4-2000DSPB stands out among 4-channel, 2000-watt car amplifiers.
