1. Fuse 30A – Replace the fuse only with the exact same style and
Ampere rating. Disconnect 12V power before changing or inspect-
ing the fuse.
2. Power Input Terminal +12V – This screw terminal connects to
the +12V battery binding post of the vehicle. Use quality insulated
wiring of the recommended wire gauge, such as wire gauge 8 or
thicker. Thinner wire may cause an overheating hazard due to the
large currents involved.
3. Remote Power Input Terminal – This screw terminal connects
to the 12V remote trigger output of some head units. When the
head unit is turned on, then the ACM-4.300 amplier will turn on.
Alternatively, you can use the GTO™ feature of the amplier so it
will turn on when an audio signal is detected at the speaker-level
or line-level inputs.
4. Power Input Terminal Ground – This screw terminal connects to
a good ground connection on the vehicle.
5. Speaker-Level Inputs – The ACM-4.300 amplier is supplied with
2 standard 4-conductor plugs that allows for easy installation and
removal. The speaker-level output from ampliers and factory
installed radios can connect here. Make sure that you follow
the plus and minus polarity markings on the ACM-4.300 and
match it to the polarity of the speaker wiring. Do not use the RCA
Line-level inputs if you are using the speaker-level inputs.
