How to Choose a Down4Sound JP Amp
Match the amp to the job: a 4-channel (JP23, JP234, JP284) for a full speaker system or to bridge into subs; a 5-channel (JP95T) to run everything from one amp; or a monoblock (JP1.2Z3) dedicated to subwoofers. Always match the amp's RMS output to your speakers and subs, and back it with proper wiring.
