Yes man the voltage drop is still there like i play the system for 15 min the voltage goes down to 13 volts and If i stop play or playing at low volume it returns back to 14.7 volts and I avoid playing at high volumes for long time. But till now every thing is ok report.
about the 6100 the current draw is max 35 amps and the average current in 4 channel 4 ohms mode ->9 amps. and in 2 channel 4 ohms mode is -> 15 amps.
And about the alpine I cannot comment as I dont have any info about the same to support. |
