Digital Monoblock Amp Speaker Connections Diagram - Subwoofer Wiring 1-8 Ohm

This document is a wiring diagram page titled "DIGITAL MONOBLOCK SPEAKER CONNECTIONS." It shows the end panel of a digital monoblock car audio amplifier and how to connect a single speaker (subwoofer) to it. On the amplifier's panel, the left side contains the POWER terminal block with three connections labeled GND (ground), REM (remote turn-on), and +12V (battery power). The right side contains the SPEAKER terminal block with two pairs of positive (+) and negative (−) terminals. The diagram illustrates a single subwoofer wired to one pair of speaker terminals: a solid line runs from a positive (+) amplifier terminal to the speaker's + terminal, and a dashed line runs from a negative (−) terminal to the speaker's − terminal. The notation "8 ~ 1 ohms" next to the speaker indicates the acceptable speaker load impedance range for the amplifier (from 8 ohms down to 1 ohm). A reader can learn the layout of the amplifier's power and speaker terminals, the correct polarity for connecting a subwoofer to a monoblock amp, and the supported impedance range. The document was uploaded to a 1994 Ford Bronco gallery as part of a car audio install ("Sundown Wiring Diagram"), but the diagram itself is amplifier-specific rather than vehicle-specific.
