Best verified amps for a single 12" subwoofer
Most single 12s are rated somewhere between a few hundred and about 2,500 watts RMS. Check your sub's own spec sheet first. The tables below list only amps whose output at a given load is confirmed in a public dyno video, grouped by the RMS range of the sub they'd suit. Every row links to the full results and the source video.
