SoundQubed C1-1100 – 1100W Compact Full-Range Digital Monoblock Amplifier

The SoundQubed C1-1100 is a compact full-range digital monoblock amplifier built for systems where space is limited but serious output is still required.

It delivers 320W RMS x 1 at 4 ohms, 650W RMS x 1 at 2 ohms, and 1,100W RMS x 1 at 1 ohm, giving installers a flexible power option for car, motorcycle, powersports, and other custom audio systems.

Its compact footprint, full-range capability, built-in crossover controls, bass boost, cooling fan, and extensive protection circuitry make the C1-1100 a strong choice for high-output builds where reliability and installation flexibility matter.
