DS18 Audio - FRP 4-Channel Class D Car Amplifier with Remote Level Control, 4 x 250W RMS at 4 Ohm - Titanium

The SXE-3000.4D/RD is a 4-channel car amplifier from the DS18 SXE series, built as a Class D design. It delivers 2 x 500 watts RMS at 4 ohms, 4 x 320 watts RMS at 2 ohms and 4 x 200 watts RMS at 4 ohms. The channels are bridgeable, so you can combine them to drive a subwoofer or a pair of higher-power speakers from the same amplifier. Total harmonic distortion is rated at 0.05% with a signal-to-noise ratio of 90dB. A selectable HPF/FULL/LPF crossover covers 40HZ-2KHZ, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from NO centered between N/A. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.

Upgrade your car audio system with the Hifonics Brutus BG 520 Watt 4 Channel Amplifier, engineered for powerful performance, efficiency, and advanced control. Designed for universal vehicle fitment, this amplifier delivers dynamic sound across multiple channels, making it ideal for powering speakers and subwoofers with clarity and precision.Built with a Class-D chipset, the Brutus BG amplifier offers high efficiency and a wide frequency range while minimizing energy loss. Its dual toroidal transformer PWM power supply provides increased power capacity and consistent output, ensuring your system performs at its best even under demanding conditions. High-tolerance MOSFET output devices enhance power delivery while supporting fast thermal dissipation for reliable operation.The amplifier features an ultra-low EMI design with shielded inductors, reducing interference and preserving clean, high-quality audio. A mass-loaded extruded aluminum heat sink improves thermal management, keeping temperatures under control and maintaining peak performance over time.Versatility is key with 4-channel operation, allowing both stereo and mono bridged configurations. High and low-level inputs make integration simple with both aftermarket and factory audio systems, while nickel-plated RCA inputs ensure strong, corrosion-resistant connections.A standout feature is the built-in UV meter display, which lets you switch between constant blue illumination, VU meter mode, or off. In VU mode, the logo reacts to your music, helping you fine-tune gain levels visually.Engineered for durability, the amplifier includes triple protection circuits, thermal, overload, and short protection, along with auto turn-on and delayed start features to eliminate unwanted noise and protect your system.

The FRP-1.2K4/TI is a 4-channel car amplifier from the DS18 FRP series, built as a Class D design. It delivers 4 x 120 watts RMS at 4 ohms, 4 x 200 watts RMS at 2 ohms, 4 x 300 watts RMS at 1 ohms, 2 x 350 watts RMS at 2 ohms and 2 x 500 watts RMS at 1 ohms. Total harmonic distortion is rated at 0.5% with a signal-to-noise ratio of 90dB. A selectable Yes, HPF/FULL/LPF crossover covers 10Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from 0-12dB centered between 50Hz. A remote level control is included so you can adjust output from the driver seat. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.
