Will hilfonics brutus 2010d mono work??

Well with the correct powering system, heaps of paralleled 12 volt Batteries, & a Beefed up Alternator to charge them, I guess so, BUT it is only Mono, so you will need TWO to provide stereo output

check to make sure your rcas are good, check to make sure all your connections to your subs are good and if they are most the time this meens your pre amp in your amplifier is out.

Hi loredo.
Hifonics are outstanding amps.
I would need a complete description of your system ( or your system to be) including High quality pictures of all amp connections and controls followed by a chat or preferably a phone call.
Let me know, and if you ever want to get rid of that amp..........

No sound in my Hifonics Brutus BXi 1206D amp

Have you confirmed that you have a good signal feeding the amp?

Have you confirmed that the speakers are in good working order and don't have any breaks in the wiring?

Hifonisc bx 1605d

i think you could but before doing that did the amp itself send the output to the line if it did then replacing the parts would be pointless. if it was a hook up problem then replace parts and don't let it happen again

Okay i have a problem hifonics brutus 1500 mono d class amp

well your amplifier is obviously going into protect mode,(i used to have this amp and it is awesome) anyway i would go through just to be sure and check all the power connections with a test light, remote wire, positive, and ground. and check the fuse to see if it is still good. you can buy a test light at wal-mart and any automotive store. if you stil have a problem then i would check to see if your running below 1 ohm on this amp. that would cause it to go into protect mode. if all this fails i would just go buy a new one.
