Dropping to 12.6? With 2000rms?

Question

I have a 2000rms hifonics brutus amp. Under the hood on hard hitting songs my voltage drops to 12.6 at the lowest... How hard is this going on my alternator? Can i turn the settings up on my amp? There only like half way? I have a redtop optima battery and at ngiht with my head lights on my lights barely dim as of now. I dont want to blow my alternator though so i just want to know if i turn the settings up on my amp and push the subs harder am i going to blow my alternator? As i said right now though the lowest i have gotten is 12.6 under the hood for voltage and that is very breife not constant.

Answer 1

depends on the alternator but most of them can handle this overload easily. They only wont output more power.
