Power & Loads

• Minimum load impedance (5-channel operation): 2 Ω
• Minimum load impedance (3-channel operation): 4 Ω + 4 Ω + 2 Ω
• Output power (RMS @ 1 % THD):
• – 5 channels @ 4 Ω: 80 W x 4 + 330 W x 1
• – 5 channels @ 2 Ω: 130 W x 4 + 510 W x 1
• – 3 channels @ 2 Ω / 4 Ω: 260 W x 2 + 510 W x 1
• – 2 channels @ 4 Ω: 260 W x 2 + 320 W x 1
• Total power: 1030 W

Installation & Compatibility

The CP 5.1K fits into systems with a 12V electrical system and operates stably at 2-Ω loads in 5-channel mode. Thanks to SPK-IN with ART (Auto-Turn-On), you can integrate it with factory radios with BTL output without a separate remote signal. The fully bridgeable architecture allows for conversion to 3-channel setups (front bridged + sub) or powerful 2-channel configurations. Adjustable input levels and crossovers facilitate clean tuning.
