The 60A fuse is WAY too small!!

The amplifier's Fuse is 80A
You will want the MINIMUM battery fuse @ 80A as well.

Since the current draw at the battery is greater because of the resistance of the wire - an 80A - 100A fuse is recommended.

The purpose of this fuse is to protect your BATTERY if something happens along the length of power wire.

What kind of "shop" are you using?? I would find another one!

I have 2 12 inch jl audio w7's with a kicker crossover and a powerbass equalizer 5 bands. i wanted to know if add a hifonics brutus 2100 d class amp to my subs at 1 ohm would it over power my subs. please...


Short answer: NOPE!

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!

My system is running hot!!!!!


your subs are the problem, not your amp, your wiring your subs paralelle, means dropping input ohmage, allowing your amp to over heat with minimal load, check the amp specs for running at low ohms, most hifonics amps are rated 2 ohms and higher, some however will run at 1 ohm, only on class b-a amps though.(competition) dropping ohmage will allow the amp to push more power to the voice coils, however the voice coils may not be rated for 1 ohm power, what ohmage are your coils rated at? do you have a min. of 100 amp inline fuse on your 1-0 awg wire? do you have internal fans? you can add mosfets to the amp but if you do so, you'll have to re-program your amps mother board.

I have a alpine M500 amplifier running a hifonics brutus subwoofer and i think it is blown. I don't understand how this could happen as the amp is only pushing 500 rms and the sub takes 600 rms. I got no...


Hmmm, let me see here. Did you mean to say you have TWO subs connected to this amp? A single sub can only be wired in series with the amp. Even if you have a capacitor wires in parallel, the capacitor is not a load, but a souce equivilant, and therefore can be merged with the amp as a single source when put on paper.

When they say a sub or amp is so many watts rms, that means that the device can function safely, without worry of failure. THERE IS NO LEGAL METHOD FOR DETERMINING THIS NUMBER AND NO REGULATIONS ON VARIANCES. Having said that, if an amp is 500w rms, it could very well push double that for long enough to blow your speaker. It all depends on how much power went through that speaker. So since you have a 4 ohm speaker, not two, and it would actually act like a two ohm speaker if you put another one in parallel because 4||4=2ohms equivilant. never never never, turn the bass all the way up if your gonna beat loud. Low frequencies draw lots of power and can damage your system.

you can tell if your speaker is blown by turning the volume to a medium listening level and placing your hand on the cone. you will hear a crackling sound if it is blown

GOOD LUCK AND PLS RATE THIS POST!!!!!!

look on the bottom of subwoofer should say like olm2412 olm1612 olympus the 1612 is the rms and speaker size 2412 is 2400 rms and the 12 stands for 12 inch subwoofer.i think thair is only 2 modles . also u have 4 u would need a 10,000 rms amp if thay are the olm2412s or 6,000 rms amp to push 4 olm1612. as far as box building info i think you should call maxxsonnics. 847-540-7700 talk to mike

Is my amplifier giving my subs the full power they need?


no sony has like 400 rms on that amp. eventualy u will blow the subbs. buy the hifonics 1608d amp to power thees subbs connect them all positives together at amp terminal and all negative together at negitive on amp terminal. this will make it a 1 ohm load with around 1400 true rms so around 500rms each sub.this amp on ebay runns like 250 and is worth every penny

Power good no green light no subs


Make sure you got a good ground. do not ground on painted surfaces! If you got power from battery, check the remote wire running to cd player. Hook up remote blue wire with the one for cd player. If you still have a problem and the fuse is good, then the amp is fried

3 amps 2 subs sound system for car, need wiring help


As i read your problem i can recommend you that connecting each of the hifonics amp to each hifonics sub with the same specs by getting the specs in interfacing the two or you can simply look to the output of the amp and the input of the sub and find a suitable plug that fits to them.

In the case if you want to run each hamp to individually run each sub but sharing 3 farad capacitor: what i can suggest is that you connect in parallel one connecting wire of each input or ouput of the amp or sub. Its like connecting a connector from each of the input or output of the amp or sub to one leg of the capacitor, and connecting two wires to the other leg, one is being connected to the amp or sub and the other wire is connected to the other amp or sub.

In the case of putting a circuit breaker at the car battery: what i can suggest is that you find an appropriate circuit breaker that fits the specs of the car battery then connect it in series on the positive supply or read the specs of the circuit breaker before you connect it to the battery. Having a circuit breaker is like having a fuse but with special advantages in favor of the circuit breaker.

In the case of having power to the amps you can run one power wire to the amps by dividing the power wire into two, one connected to the amp and the other wire to the other amp. Then you can connect each amp and sub in series individually by connecting one wire b/w amp and sub. I hope i solved your problem

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?
