Best all-round amplifier

Kicker 53VXA3501 350W Monoblock Class D Subwoofer Amplifier

A 1-channel amplifier option for adding cleaner headroom to a planned car-audio system.

What we like

Lowest listed price in this comparison at £189.99, £9.96 below Kicker 46CXA4001.
The only pick here listing 350W power, giving it a clear difference from the other 5 options.
The listed 1-channel layout makes its intended role easier to match to speakers or a subwoofer.

What we don't like

Unlike some alternatives, the listing does not show a comparable channels figure, so matching it to the rest of the system takes more checking.
A mono layout is intended for a subwoofer rather than a full speaker system, so it is less flexible than multi-channel picks.

Buying guide

What to check before ordering

Match the amplifier to the speakers or subwoofer at the correct impedance. Plan power cable routing, fuse placement, signal cables and ventilation before deciding that the largest watt figure is the best fit.

Use the model number as the final reference. Retailer images and prices can change, and vehicle fitment should be confirmed for the exact make, model and year.
