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.
