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 @ 1 ohm (not really disputed), 700 rms x 1 @ 2ohms, while others say 500 rms x 1 @ 2 ohms
- What guage wire did you use with this Amp?

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

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:

and 4awg wire

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).

hmmm, are dummy loads just resistors?

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?

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....
