Use the DC Audio 250.4 Class D 4-Channel Amplifier when comparing DC Audio multi-channel amplifier options for a speaker-focused system. This page keeps the original output ratings, electrical requirements, dimensions, filters, and included features together so the amplifier can be matched to the actual build instead of selected by a model name alone.
A speaker amplifier should be selected around the speakers it will power, their impedance, the number of channels needed, the intended crossover points, and the available electrical support. Matching those details helps the amplifier, speakers, wiring, and source signal work together as one system.
