• Protection suite: thermal shutdown, short-circuit protection, overload protection and DC offset protection for safe operation and reliability
• Compact design for easy installation in most vehicles
• Stable performance at typical car electrical voltage (14.4 V)

Technical specifications:

• RMS Power @14.4 V :
  2 stereo: 150W x4
  4 stereo: 85W x4
  4 bridged: 295W x2
• Crossover: adjustable (user-selectable), 12 dB/octave slope
• Frequency ranges provided: 50-250KHz ; 120-3KHz (confirm intended units)
• Protections: thermal / short circuit / overload / DC offset

Benefits & use cases:

• Full-range systems: drive a 4-speaker setup with clean, punchy output at 2 or 4 .
• Subwoofer bridging: bridge channels for two high-power subwoofer channels (295W x2 at 4 ).
• Tunable sound: adjustable crossovers and 12 dB/octave slope let you tailor the sound to your speakers and vehicle acoustics.
• Reliable operation: comprehensive protection circuitry reduces risk of damage and downtime.

Installation & compatibility notes

• Requires a stable 12V car electrical system; power rating specified at 14.4 V (typical while engine running).
• Use appropriately gauged power, ground, and speaker wiring; for bridged/subwoofer connections consult wiring diagram.
• Ensure proper ventilation to avoid thermal shutdown.
• Recommended professional installation for complex systems or if unsure.
