Hello, i have a hifonics brutus also, in the manual it states to set the eq at half way, so that there is no clipping or at least to prevent clipping , the eq will make the bass punchier, if you do go pass half way, i would recommend to readjust your gain settings, also check your head unit settings and make sure everything is flat, bass, mid bass etc. example i had my eq past half but i had my gain at mid way, it was hitting hard, then i tried turning the eq all the way down and the turning up the gain and the bass was smoother so it depends where you set it, and what settings you have on your head unit tone control (bass, treble etc)

Re: setting low pass and bass eq
Ok then you dont want to put the gain to max. back off it about an eighth of a turn. turn on the low pass filter and you will be good to go. if you have any more questions email me at firstname.lastname@example.org

Do to the impedance Of your sub u can't run it @2ohms its going to either be @1ohm or 4ohms and your amp isn't 1ohm stable and u will risk damaging your amp. So your only option is to run it @4ohms and on a good note your sub is 100-600 watts RMS and your amp will push 400-500 watts RMS @4ohms. Now if you want to run 2 sub's in the future That amp will work perfect because it pushes 1,200watts RMS @2ohms and to wire your 2 sub's @1ohm just follow the steps in the image below. Hope this helped.
The Hifonics Brutus 2100 is stated to produce 2100 watts RMS @ 1ohm load. Most amplifier manufacturers overstate their claims. The 2100 watt output is most likely at 14.4 volts and not the 12.6 volts your car will actually be providing the amp.
But, even if the actual output was 2100 watts that would be 1050 watts to each 12w7. The 12w7's are rated at 1000watts RMS and 2000watts peak. As a MECP certified installer, any system I have done using 12w7's have had a MINIMUM of 1000 watts being provided to each speaker. My personal preference is to run 1500 watts each and keep the gains adjusted lower on the amp. Thus allowing the amp to run cooler and allow the additional headroom for those "show-off" moments!
Bass drum by convention is ch1 on the board. You need a good drum and a good mic
First set eq flat and pfl ch1, set gain control so drum just hits peak/or red when hit hard.
Send ch to drum group (1+2) on board, or route to master (L+R), depending on type board. Then listen to drum ONLY through the system, and adjust eq so it sounds good at low level then turn it up and keep it sounding good. If it keeps peaking the ch then turn down gain.
There are toys (inserts) you can use noise gates and compressors if available,
Sound is objective and can not be learnt without doing it , good luck. remember good low level sound will always be better than really bad lound sound, start low make it good then make it loud.
Good drums do not need much eq. Get the drum right first.
Really it all depends on how you want them to sound, and to be set up. There really is not specific air space, but there are general air spaces that work, and some times the manufacture will list some specs for different set ups. It also depends on the size of the sub, which you did not specify.
Kicker recommends as follows.
0.4 cubs per sub for a compact box, and 1.8 for an SQ box. SQ stand for sound quality.
So if you want a small box, do .4 per sub. If you want a better sounding box do 1.8.
Rule of thumb and something to think about.
The more air space in the sub, the less power you can run, the less air space, the more power you can run.
For example you can run 200 watts RMS per sub at .4 cubes, but only 140 watts RMS with 1.8.
As well, the smaller box will be louder, But not sound as good.
Subsonic refers to frequencies too low for the human ear to hear. Generally humans can hear frequencies in the range of 20 to 20000 hertz (cycles per second), but we hear best in the range of 1000 to 4000 hertz. High amplitude subsonic frequencies can cause damage to your speakers so many amplifiers have an electronic filter in them to reduce the amplitude of these very low frequency signals.
it all depends on the impendance of your subs if u have duel 4ohm or duel 2ohm, 2 duel 4ohm speakers can be wired at 1ohm to the amp, and with a kx1200.1 that would be pushin 2400 peak and 1200rms if ya have 2 duel 2ohm speaker than you can only wire them to 2ohm and would be pushing 1200 peak and 600 rms with the kx1200, so if you have the duel 4ohm i would go with the kx1200.1 and if u have the duel 2ohm i would go with the hifoncs
