well guys. i have no idea what is going on but i cannot power my subs for some reason.
all of my wires is connected correctly to my Audiocontrol LC2i (tapped front speaker wires for signal) and rca going to highs amp and rca going to lows amp.....
for some reason my subamp isnt getting any signal at all. its not the amp because this is the second amp i tried (brand new)
i tried switching hte rcas and they both work for the highs amp, i also tried the sub output in the lc2i to the highs amp and it still worked so i know that output is working...
Its not the audio control unit because i also tried two seperate units (my friend has an LC6i and stilld oesntr work)
Not sure what happens but when i turn the gain up on the hifonics brz 2100 the amp goes into protect mode (while producing no sound)
Not sure what the deal is here this never happened to me before i sent my LC2i out for repair.... i never touched any wires and re-checked all the wires but still cannot get the freaking sub to work
i honestly do not know what is going on
the thing is i had my other sound system working perfectly fine, last month i sent out my audiocontrol unit out for repair and then i got it back and no sub working
ON THE OTHER HAND!!!!!!!!
THE LAST TIME I HAD A SUB WORKING WAS BEFORE MY SOUNDSTREAM TARANTULA AMP GOT MESSED UP!!!!
my car battery was dead and i heard a popping boom sound from my subs and thats when my amp went into protection mode..... (the old soundstream)
anyone have any ideas? maybe my headunit is messsed up not giving the full range of signal anymore?
Check the amp. Does it have a master slave switch? If so make are its set to master. Check you filters. Make sure they are set correct and not too high or low. Is the amp on? Status led lit up?

yep,. i have a hifonics brutus 2100 and its set to master (the slave)
i cant even get any signal man! (without my subs even being connected)
the amp is on and working, my lc2i is on and working (i tried 2 differnt line out converters from audiocontrol)
for some reason when i turn the gain to like half it goes into protect mode.

im not really sure this is VERY frustrating
If it is working, and when you crank the gains up, you could have an issue with your sub/wiring configuration,and also a bad ground ,couple things to consider.Id check the wiring configuration on the subs to make sure you have the ohms load correct for that amplifier to run at

no its not working (well the amp is ON, but there is no signal coming out to my subs so my subs arent even connected right now, with my subs DISCONNECTED it's still shutting off (protect mode when i turn the gain up past half without anything connected to the amp besides teh rca input
you guys think it could be a head unit problem? i will take out my ground and re connect it, but i dont think its a ground issue because the amp is on
although i did not sand down the chassis where its connected to but i had 2 other systems connected to the same bolt and they were both perfect
Do you have a head unit? (aftermarket) I'm assuming factory head unit. But I'm not familiar with the line out converter you have. Have you tried hooking the sub channel to the rear speaker line? Does the LOC have it's own gain settings? A groundwire to hook up? Post a link to it if you would.
When you got the popping sound from the subs at that one point earlier, you could have damaged a voice coil on one of your subs also??
no that was with the old subwoofer and that subwoofer is still fine i have it in my boat
also this is a new amplifier im using not the old one
i bought a precision power black ice bk 1800 from sonicelectronix and it had this same problem, so i returned that cuz i thought it was defective and bought the hifonics brutus and now its same problem again
this is a completely new system from power and ground wires, to subs to amp
have you tried to bypass the audicontrol unit yet from straight hu rca out to the amp just to see if it may be the sub section on the audiocontrol unit(dont even hook it up,just bypass for testing??

audiocontrol LC2i is what i have for a LOC (its a digital sound processor as well)
the ground for the LOC is connected to the ground of the highs amp and the 12v is connected to the power (12v of the highs amp also)
ive had it connected liek that for 7 months and worked fine then i sent it out for repair and they replaced the entire unit for another issue that i figured out had nothing to do with the lc2i unit but yeah...

i have a factory headunit otherwise i wouldnt be using the lc2i lol
the factory unit doesnt have any rca outputs its a 2008 honda accord LX

also i tested both rca outputs on the LC2i for my speakers and they both work on the main output RCA and the BASS output RCA, they both give my speakers sound so im not sure
Just a thought but I throw money away a lot. Lol. Could you run to Walmart and buy a cheap scosche line out converter for like $20? Could just try that and if it solved the problem it's the audiocontrol piece. Positive the settings are correct or set to sub on the LC2i? Does the amp itself have a high level input?
Go buy a phono to rcacable for 4$ and plug your phone into the amp... does it work?
If not, look at the amp, if so, look before the amp..
Simple

well my lc2i unit is brand new ( i have a brand new motherboard in it)
and my friend has an un-opened audiocontrol LC6i that i tried to use and still the same thing
so something is happening between the LC2i unit and the rca input of the amp (it does not have a HPF on it if thats what you mean lol
LOL sorry..when I think of AudioControl,Im thinking of a preamp.You have the rear wiries hooked up for sub out on the converter/rt/left?You say?
what? lol
the only way to hook up the lc2i unit is by tapping into the factory speaker wires for signal and send those wires (right and left) into the lc2i unit.... then frm there just take RCA's to each amp (one for highs and for sub) and thats it

Right a LOC/Line Out Converter..AudioControl make several Xovers/preamp eqs,and have for years,is what I thought you were talking about at the beginning,not asking about an LOC,or a stock HU..Those LOC can be a PITA at times,ive had to run to all High level inputs before,and took some time doing so, as I had an issue with the rca out on them.I dont even mess with them anymore,I just do a HU with min of front,rear/sub out rca now,can be had cheaply, and be less of a hassel
i plugged in my iphone with an rca directly into the amp and it played VERY low and when i barely turned on the volume to like 1/4 of the way it goes into protect mode... my powerwire is very secure and my groundwire i just took it out completely, sanded down the chassis more and reconnected very tight.... so now what could be the problem?
this is the second brand new amp i tried from sonic electronix completely sealed and both the same issue... so theres 2 things its either somehow the amp again, or the power and ground cables, which makes no sense at all for it to be the wires, i just re-checked the fuse and re-did the ground (0 gauge wire) and i have the big 3 upgrade done too, i checked the voltage AT the amp by plugging in my DMM probes to the 12v power wire and the ground and it said the amp is recieving 14.2-14.4 volts
any ideas guys before i pull the plug on this and pay shipping for a new amp again
disconnect the sub, or put ANY old speaker you have lying around on the amp (gain all the way down of course) Does it go into protect?
The sub could be bad or hooked up with too low of an ohm load for the amp, putting it into protect..
Hard to say..

Just adding to what was said. But it does sound like a speaker is bad or coil. Or wiring is grounding out between the amp and speaker or the speaker terminals themselves.
Please help :(
Re: Please help :(
..Those LOC can be a PITA at times,ive had to run to all High level inputs before,and took some time doing so, as I had an issue with the 
Linear Mode
