Diamond NEO12004DSP

Four Channels of Power. One Platform of Control.

The Diamond Audio NEO12004DSP delivers 1200W RMS total system power in a compact 4-channel design—perfect for powering full-range speakers or running a front stage + sub setup. Need flexibility? Bridge it to 600W x 2 @ 4Ω for serious output while maintaining the clean, detailed sound Diamond Audio is known for.

Built-In DSP = Total System Tuning

Eliminate the need for external processors with full onboard DSP:

• 31-band parametric EQ (per channel)
• Active crossovers & time alignment
• Channel linking for advanced setups
• PC & Android tuning interface

Dial in every speaker in the vehicle with precision—cleaner installs, better sound, more control.

OEM & EV Ready Integration

Built for modern vehicles and seamless installs:

• High & low-level inputs (0.4V–20V) for factory system compatibility
• Selectable load resistors (10Ω–20kΩ) for proper OEM signal matching
• 8V–17V operating range – safe for EV & hybrid vehicles

This is the amp you bring in when integration matters.
