My new a2100d power accoustik goes into protect mode when i turn it up loud... its 2000w rms
and to avoid people asking: 1) Impedence is 2x dual4 ohm Cerwin Vega 10s = 1ohm 2) Amp is 1ohm stable mono amp 3) Gain is below 1/4 4) I have a 140 amp Alternator
im thinking it might be the fact that its hooked up with 4 guage?
