A single-channel or monoblock amplifier is used to deliver
power through one channel to one or more speakers. This single power signal is
ideally suited to the low frequency design of a subwoofer. Mono-blocks provide
optimum power output efficiency. They are limited in frequency range, and are
thus not full range amps. With only one channel, monoblock amps are not
capable of amplifying a left-right split stereo signal. They can power more
than one subwoofer. SoundQubed designed the S1 Amplifiers to provide the best
dollar per watt value on the market. These amplifiers feature high voltage
output devices, strong power supplies, and all the necessary pre-amp controls
to perfectly tune your vehicle’s subwoofer stage. S1-850 S1-1250 S1-2250
