ARC Audio Amplifier Foundation
Choose ARC Audio Amplification by Channels, Load & System Demand
An amplifier should be selected after the speaker, subwoofer, signal, and channel plan are clear. SMS matches ARC amplification to the actual impedance, crossover strategy, usable power, installation space, cooling, electrical capacity, and future system direction.
Plan the amplifier around the complete channel map.

Useful amplifier power depends on more than the number on the box.
The amplifier must work with the real load, source signal, driver protection, thermal environment, electrical system, and intended listening use.
Input SignalConfirm source voltage, balanced or speaker-level requirements, factory processing, turn-on behavior, noise risk, and DSP routing.
Output ChannelsMap each speaker and subwoofer channel, impedance, crossover, bridge requirement, and expansion plan before selecting the chassis.
Setup & ProtectionSet gain structure, filters, limiters where available, polarity, and safe operating ranges around the actual drivers.
Electrical & ThermalSize cable and fusing, verify grounds and charging support, provide airflow, and keep the installation serviceable.
Where Music Matters
Choose the amplifier after the system map is complete.
Send the vehicle, source unit, speaker and subwoofer models, final impedance, channel plan, available mounting space, and electrical upgrades. SMS can supply the amplifier alone or complete the wiring, installation, integration, and tuning.
