Best all-round amplifier

AudioControl LC7iPro 6-Channel Line Out Converter with Accubass®

A 6-channel amplifier option for adding cleaner headroom to a planned car-audio system.

What we don't like

  • Unlike some alternatives, the listing does not show a comparable power figure, so matching it to the rest of the system takes more checking.
  • The amplifier or processor still needs matching to the speakers, subwoofer, impedance and available installation space.

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.
