4 Channel Amplifiers

Browse four-channel amplifiers for a speaker upgrade. Decide which speakers you want to power, then compare each amplifier's output, input connections and adjustment options with your system.

Keeping the original head unit may require additional integration parts. Ask Garage Audio to inspect your vehicle and confirm the amplifier, wiring and installation requirements.

Compare amplifiers with DSP or ask our Morayfield workshop about your upgrade.
