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 Te12V – 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 amplifier will turn on. 

Alternatively, you can use the GTO™ feature of the amplifier 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 amplifier is supplied with 

2 standard 4-conductor plugs that allows for easy installation and 

removal. The speaker-level output from amplifiers 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.
