4 Channel Car Amplifiers

4 channel car amplifiers give you a way to power multiple speakers from one amp, with options for different system goals and installation needs. We carry models with a range of RMS ratings, crossover controls and connection features, so you can compare the specifications before choosing.

How to choose a 4-channel car amplifier

Start by checking the RMS output at the impedance you plan to use, then compare it with your speakers’ requirements. The Audiopipe APTV-600.4 is rated at 60W x 4 at 4 ohms or 100W x 4 at 2 ohms. For a different output option, the SoundQubed C4-2800 delivers 350W RMS per channel at 4 ohms and supports bridged operation.

4-channel amp crossovers and setup features

Built-in filters can help tailor the signal for your speakers or subwoofer setup. The Audiopipe APTV-600.4 has adjustable crossovers, while the Audiopipe APTV-1000.4 offers adjustable 40–400Hz crossovers and is rated at 4 x 100W RMS at 4 ohms. Check the product specifications for input connections and installation details that fit your system.

Marine 4-channel amplifier options

For marine audio, the Massive Audio TX48 Trident is rated at 400W RMS per channel at 2 ohms and has selectable crossovers and a coated circuit board. Consider the system’s speaker load and available installation space when comparing models.
