DS18 ION700.2D Compact Full-Range Class D 2-Channel Stereo Amplifier 700 Watts RMS

Delivering 700W RMS when bridged at 4 ohms in a compact, full-range digital design, the DS18 ION700.2D is built for high-performance installs where space is at a premium.

• RMS Power (Bridge) 4 Ohm: 700W; enables a strong, single-channel drive when you bridge the two channels for a sub or dedicated bass path.
• RMS Power (2 Ohm) 2 Channel: 2 x 350W; each channel can push 350W into a 2-ohm load, ideal for a robust front-stage or midrange amplification.
• RMS Power (4 Ohm) 2 Channel: 2 x 240W; provides ample power for stereo channels at 4 ohms with good headroom.
• Total Peak Power: 2100W; a measure of the amp’s instantaneous capability across the full system.
• Frequency Response: 10Hz–20kHz; ensures coverage from deep bass to crisp highs for a full-range presentation.
• Signal-to-Noise Ratio: >95dB; low noise floor contributes to cleaner audio with less hiss and hum.
• Efficiency (4 Ohm): 88%; high efficiency supports cooler operation and reduced electrical load in daily driving.
• Damping Factor: 210; helps control speaker cone movement, improving bass definition and transient response.
• Input Impedance: 27Kohm; high input impedance reduces loading on source units for clearer signal transfer.
• Channel Separation: 59dB; minimizes crosstalk between channels for more precise stereo imaging.
• THD: 0.01%; low distortion contributes to cleaner, more accurate sound reproduction.
• Bass Boost: 0–12dB at 45Hz; adds controllable bass presence without muddying fundamentals.
• Crossovers: LPF/HPF/FULL, 40Hz–2kHz; tailor output to sub, front, or full-range, reducing frequency overlap.
• Bass Boost Frequency: 45Hz; precise boost point aligns with typical sub-bass content.
• Remote Level Control: Yes; makes quick level matching convenient from the seating position.
• Hi-Level Inputs: Yes; facilitates integration with factory or aftermarket head units.
• Tiffany RCA Terminals: Yes; high-quality signal connectors for reliable, low-resistance transfers.
• LED Indicators: Power / Protect / Clipping; at-a-glance status for quick diagnostics.
• Protection & Safety: Thermal, Over-Load, DC Offset, DC Output, Short Circuit, Voltage, Clipping protections; protects both amp and speakers.
• Power Input & Fusing: 4 AWG terminal; 60A external fuse; solid power delivery with external protection.
• Construction: Aluminum chassis with Black/Silver finish; durable, heat-dissipating enclosure.
• Dimensions: 6.14" L × 4.72" W × 2" H; compact footprint suited to tight installs.
• Heatsink: 4.84" heatsink length; supports passive cooling without a fan for quiet operation.
• Weight: 0.75 kg; lightweight for its power class and easy mounting.

In a real-world build, the ION700.2D fits behind a dash panel or under a seat while delivering substantial bridge-grade power or dual-channel output for a refined front stage. The combination of Hi-Level inputs, Tiffany RCA terminals, remote level control, and comprehensive protection keeps installation flexible, responsive, and reliable across varied automotive environments. A moisture-resistant coating on the PCB enhances longevity in humid or damp conditions, while the absence of a cooling fan reduces noise, letting you hear the music rather than the hardware.
