If You Own a HIFONICS BX1000D Amplifier Please Look Here

Hey guys! What's going on? I have 2 questions for all of the HIFONICS BX1000D Amp owners out there:


What was the true rated power of this amp? What did the birthsheet say? There has been some confusion about this, as some sites say 1000 rms x 1 @<hidden> 1 ohm (not really disputed), 700 rms x 1 @<hidden> 2ohms, while others say 500 rms x 1 @<hidden> 2 ohms
What guage wire did you use with this Amp?

[sinister audio]

i think they make rated power or very very close to it. i dont think they have a birth sheet. use 4ga. id say it makes 700watts

[William from NOLA]

The gauge of wire depends on the distance it is run. Typically 4 gauge would be enough, but for safety's sake read this section of the FAQ's:

Its going to be installed in the trunk of a Saturn SC2 coupe if that matters...

For real specs i might check out hifonics site...whatever it may be or send them an email.

4 gauge wire should be fine for that amp.

how to bench-test your amp at home: http://www.bcae1.com/measpwr.htm

and 4awg wire

[William from NOLA]

The only problem with bench testing is that dummy loads are expensive. There are some that are 4 ohm, but only handle up to 100 or 200 watts :(.

I say find one that is 8 ohm or so (lower) with a higher (200-300 watt) power rating. The only thing is that it won't be as accurate for say a 1 or 2 ohm load's output (using math to find that).

[nist7]

hmmm, are dummy loads just resistors?

[William from NOLA]

Yea, they just cost a lot for high power handling. The typical resistor in a circuit doesn't really need a huge power rating (most of the time).

Maybe you could rig up a series circuit with several smaller resistors, no?

[nist7]

I see how it is. Super-tough resistors that can take the heat!

Anyways, I think it's probably ok to wire up a series of smaller resistors. The final resistance would still be the same and the power dissipation would be shared amongst the resistors rather than having one resistor take it all.

But I'm not so sure though. Maybe KiKi can jump in to verify this....

The new hifonics site only has their new line specs not the older ones...

Will 4 gauge be okay even if I upgrade to another amp for a 1 ohm load...

[ridr4lif]

If you think you might be running a larger amp later on, then run a bigger wire now.

As for the specs on your BX1000D, email them. Im sure they have the specs in a file somewhere and be more than happy to email them to ya.

you need a non inductive resistive dummy load. you can make your own with an old hair drier if you're in a pinch.
the heating coil just has to be taken out of the device, and unwound.. then measured and attached to a heat spreader. that'll serve the purpose.

[GlassWolf]

and if you're going to run more than that brutus now or later, just run 1/0AWG cable now and save the hassle later.
split to 4ga at the amp with a fused d-block and use 4ga for ground.

Im going to be using just the brutus and nothing more

[GlassWolf]

no amp for the front stage or rear fill?
that system is going to be severely mismatched for power. the bass will overpower any vocals or treble. you generally want two thirds of your power for subs and a third for mids/highs.. as a rule of thumb.
always exceptions. I've had more power to front stage than subs before in systems, but usually you want that 2/3 split.
that means if you're going to give the sub)s_ 700 or so watts, you'll want around 300 watts for the rest of the system to balance it out.

[ridr4lif]

Intersting Kiki.

Ive never heard that before.

Ill have to keep that in mind when designing my next system :thumbsup
(like that will ever happen)
