Choosing an Amplifier
Match the amplifier to your system:
- Channel count: two channels for a pair of speakers, four for front and rear pairs, six for a larger system
- Power rating against the speakers you are running
- Built-in DSP, as on the Cicada Audio PRO models and the Diamond Audio NEO models
- Size and mounting: compact units fit tighter spaces
- Your model year, since mounting racks and wiring are year specific
