2 hifonics brutus 1606d on 1 15" fi btl

[matteron 0]

would anyone recommend running 2 hifonics brutus 1606d mono class amps to a 15" fi btl sub at 2ohms and connecting each voice coil separately if no. why not?

no, i don't think those amps are master/slave compatable , meaning they can't do EXACTLY the same output at the same time so each voice coil would be getting different voltages goign to them = blown BTL

why 2ohms? that would be the same as running 1 amp at 1ohm...

thanks for the warning bassINyoFACE. i just wanted to make use of my 2 hifonics 1606d mono amp but i guess i will just end up having to purchase another amp with at least 2300watts rms at 2ohms to power my 15" fi btl. i chose 2ohms because the amp would run cooler and not really under any stress as opposed to 1ohm

well in all of my experiences, if the amp is rated to do 1ohm, it should be good to go. all of my amps never got beyond warm at the most, and imho, running two amps to do the same thing/power is just a waste of money...if anything, buy 1 nice amp, and use the saved money to get an extra batt, or something to help relieve some "stress" on it

WRONG!!!! there is nothing true about that statement.

The voice coils creat a magnetic field that add together. Does not matter if they are not exactly the same.

Even a sub with coils in parallel on a single amp can have variations between the coils, wire to the coils, connections, etc. that can make the voltage drop slightly different on each coil.

Some people leave one coil of a DVC open, shorted, or use a resistor across it to vary the Q.

I have seen passive crossover designs in home speakers that use a lower LP frequency on one coil than the other to give the driver more output on the low end, while still having output that blends with the midrange.

As already stated, running a single amp at 1 ohm will be almost the same power as 2 amps at 2 ohms, BUT the efficiency should be higher at 2 ohms. It should also be less stress on the amps running them at 2 ohms, which is a good thing, since everyone seems to hate Hifonics

If you already have the amps, give it a try. . .you might like it.

with two different amps you would constantly have to match the gains and herts knobs on the amps due to the vibration on the sub. youpprobably wont hear the difference, but personal preferance run one amp.

Id have to say run one amp also..

Would be so much easier..

You get that much vibration on a hifonics amp, parts are going to fall out of it. . .I know from experience.

You guys crack me up. . .I ran (8) MD3D's on (2) RE MT 18's. Not a big deal. . .Get the gains close with a DMM, set the low pass filter (AKA "herts knob" ) and SSF just using the markings on the amp, and you are good to go.

Please do your homework before you pass on missinformation like this...

thank you'll for the input i am just gonna buy a new amplifier.
