Amplifiers
Category Guide & Buying Information Fitment, power & selection tips
Shop monoblock, full-range, and multichannel car audio amplifiers for subwoofers, mids, highs, and complete systems. Compare rated RMS power at your intended impedance, channel count, efficiency, dimensions, input options, and required power and ground wiring.
Choose an amplifier using RMS ratings—not maximum wattage—and match it to the final speaker or subwoofer load. Higher-power amplifiers may require a Big 3 upgrade, larger OFC cable, additional battery capacity, or a high-output alternator. CAS can help check the full system before you buy.
