The lights will still flicker if the system is played loud for more than 30 seconds.  I have not tried the GloweVoltage yet, but I'm hoping to soon.  Anyhow, if you have a system pulling 300 amps and an alternator supplying 110 amps, it won't be long until those batteries are dropping below 12v.  We also know that the more voltage you have, the more power the amps put out.</blockquote>
