Power-matched options for one subwoofer or one complete loaded enclosure. We aim to include same-brand choices when their ratings qualify.

Suggestions use 75–125% of the subwoofer’s RMS rating at the wiring load shown. Check wiring, enclosure needs, electrical capacity and installation space. Set gain and filters correctly to avoid overpowering the subwoofer. Buying more than one subwoofer changes the match.
