Page 14: System Planning
System Planning ► Impedance (Loudspeakers) (Ohms) ► Impedance is the resistance to the flow of current in AC circuits. DC resistance can be measured in ohms (Ω) using a multimeter. ► Full-range loudspeakers are usually 4Ω or 8Ω impedance, while Subwoofers can be Single-4Ω, Dual-4Ω... - Page 15 Si2000.4 4-Channel | Specification Amplifier Topology: Class AB / 4-Channel Bridgeable Power Supply: High-Efficiency MOSFET Power Output: 2000 Watts Peak / 800 RMS Recommended Fuse: 80A External (not included) Continuous Power (RMS) @ 14.4V: 125 RMS x 4 @ 4-ohm 200 RMS x 4 @ 2-ohm 400 RMS x 2 @ 4-ohm Bridge Features:...
