Battery and charging system
KAC-1021 amplifier draws enough current to put a substantial additional demand on automotive eiectricai systems. When piayed very loudly, the KAC-1021 may draw 20 to 40 Amperes on the average, with peak demands up to 120 Amperes!
A typical stock battery and alternator in good condition will handle moderate to low average levels, with occasional brief episodes of hard use. However, alternator and battery life will be shortened. We strongly recommend that a premium deep-cyde battery and heavy-duty alternator be used with KAC-1021 systems.
If the sound system will be used when the car is not running, the battery will obviously be
discharged ~ perhaps enough to prevent restarting. The discharge/recharge cycle will reduce
battery life, and alternator life will be shorter because of the high-current recharge requirements.
If problems arise:
a} Use a premium battery or deep-discharge marine battery. b) Use a heavy duty alternator. c) Use a trickle-charger or battery charger. d) Install a second battery for the amp, with a switching system for recharge.
