Battery considerations
Amplifiers will put an increased load on the vehicle’s battery and charging system. We recommend
checking your alternator/stator and battery condition to ensure that the electrical system has enough
capacity to handle the increased load of your stereo system. Stock batteries which are in good condition
should be able to handle the extra load of the HS4 amplifier without problems, although the life can be
reduced slightly. To maximize the performance of your amplifier, we suggest the use of a heavy-duty
battery or a second battery, dedicated to your NUTV5 system.
