8.  Power LED – If you have connected your battery power, vehicle 

ground, and turn-on lead (or GTO™ signal sensing) correctly, then 

this light should turn on to indicate the power is ON.   

9.  Protection LED – The ACM-2.300 amplifier has built in diagnostic 

codes to tell you exactly what is going wrong should the amplifier 

detect a problem. If the protection LED should come on, read the 

flashing

 

codes quickly before turning off the system and investi-

gating. (See the specs page for a list of diagnostic codes.)

10. GTO™ Signal Sense – In the ON position, the ACM-2.300 amplifier 

will turn on gracefully when it detects an incoming audio signal, 

and it will turn off after a period of time when the audio signal 

fades away to silence. In some situations, factory installed audio 

systems may turn on or “wake up” due to convenience features 

like door chimes, alarms, and cell phone signals that trigger the 

source unit in the vehicle to come on. To prevent these from 

turning your audio system on unexpectedly, you can bypass the 

GTO™ circuit by moving the switch to the OFF position and use 

a switched 12-volt signal connected to the Remote In terminal 

instead. 

11. High Pass Crossover Frequency – Since component speakers 

(like woofers) are designed to reproduce certain frequency ranges, 

a crossover allows you to match the speaker to the appropriate 

frequency range. Most manufactures list a recommended cross-

over frequency as part of the speaker specifications. Choosing 

the correct crossover point will provide increased speaker 

reliability and optimum sound quality. The ACM-2.300 amplifier 

has selectable 12 dB/Octave Linkwitz-Riley crossover points at 

80 Hz, 120 Hz, and a “bypass” option. The amplifier receives the 

frequency range above the crossover point. Select the crossover 

frequency on the ACM-2.300 amplifier to best match the value 

specified by your loudspeaker’s manufacturer. If you do not know 

this value, select the position that suits your system best.
