ok it been awhile but im sure I know how to do this. Ok I have my Hifonics Brutus BRZ 1200.D hooked up to my 12"Fosgate p3 dvc 4ohm. sub is parellel to 2 ohm.

downloaded a 0db 60htz test tone. stero bas is at 0 on factory radio. turned amp gain all the way down put digital multimeter on subs with amp hooked up.

2. played test tone in repeat with radio at 3/4 volumn

3. I can turn the gain up to 42 volts before i hear any distortion.

If my calculations are right thats around 950 to 975 watts rms out of this amp

my p3 in a slot port enslosure at 1.8 cu, sub settels nicely at this level turned up to max excursion and turned down till sub setteled. hits so freeking hard.

I wonder how long this sub will last at 900 rms lol.

I might be looking into getting a new sub soon.

What do you think about this setting?

I dont think my neighbor likes it to much, even though he cam out to check it out and He want a system now. He said I was viberating his house lol.

Thanks for any comments
