Hey,
I am installing my amps tomorrow. They will be 2 hifonics brutus bxi 2601d's I am using each one to power 1 12" re xxx. My question is what volts do I aim for when setting gain. Each re xxx will be 1 ohm and getting 2600 watts (i know its overated) I used JL audios way to set my 1000/1 and that told me what volts to set the gain at. HOw do I know for these amps. Once again 2600 watts at 1 ohm. Any help helps, as I am doing this tomorrow!! Thanks in advance!!!

Being 2000w subs I would set it for 2000.
BTW - HF swears the 10 series are capable of rated power at 14v. They have some internal upgrades over the older models.
E = sqrt(P/R), E=sqrt(2000/1), E=sqrt(2000), E=44.7v
Hopefully you already have the 50hz 0dB tone on disk.

Thank you so much!!!! So each amp will be set at 44.7v Thanks for all the help. The hifonics explanation in the manual was a joke,,, I laughed for 6 1/2 hours!!!

the manual's method is the quickest and easiest procedure for a novice.
I've found my results using that method are very comparable to using a DMM.

Another question. I can get the amp to read 14 volts when I touch the positive and negative 0 guage inputs, but when I follow the rules for setting the gain I get like a wierd .02 no matter where gain is turned. I have done this before on a slash series 1000/1 JL amp with success. Any ideas on what I am doing wrong??? I dicconect the positive speaker. Use my 50hz 0DB cd. Put gain all the way down. I put head unit 75% up, and I place positive on positive speaker terminal, and negative on neagtive speaker terminlal. DMM on same setting that reads me 14 volts . Any ideas???

You need to set your DMM to AC not DC.

^seeing as this thread is from may and the OP hasn't been on since june, i would venture to guess that you will never get an answer.
