    Re: voltage dropping

    OCV of the 2400 with the car off should be no lower than 12.7 volts (12.8-13 is normal). If it is your alternator is not keeping up with the demands of the audio system and you either have to get a bigger alternator or give the alternator time to put a charge back into your batteries.
