I am looking at a Hifonics xxv Colossus amp to run three audioque subs they are dual two ohm. and they will wire down to 1.34 ohms. It is 1 ohm stable and will produce 1600 watts per channel. the amp will produce 3200 watts bridged at 2 ohm. would the amp work bridged at 1.34 ohms?

Remember that hifonics amp are overrated by about 20% so factor that that in....... they're also not the greatest quality but ok.

Not "all" Hifonics are overrated..The txi and brutus line yes, PPL kill with that one...The Colossus will do its rated power. Since you have 2ohm AQ I would say you have the HD3... I think you find a better amp in the same price range.

" Not "all" Hifonics are overrated..The txi and brutus line yes, PPL kill with that one...The Colossus will do its rated power "



From a benchtest article of the XX Goilath:

" When I began to measure power levels, I found the power at 1.0% THD+N was a little lower than quoted in the specifications. After double checking all my measurements, I realized that Hifonics does not qualify their power figures with a distortion limit. By letting the amp run a little into clipping, I could get the claimed power from it, but at distortion levels around 2% to 5%. "

I would imagine the XX Colossus would be similar since it's the same line.

So where do you get 20% from M.S.

At no point during the power testing did the amp complain or show any sign of stress - it just kept cranking out gobs of power."

^^^^ Didn't I just post that, lol


In that test the amp was overrated by about 8%...... the Bxi and lower lines are known to be about 20%. The point is they are overrated, where as you claimed they do their rated power.

Where did I say the Brutus put out the rated power???? I said txi bruts yes...Meaning they are overrated..LOL ...Yes you did post that with out the part... "At no point during the power testing did the amp complain or show any sign of stress - it just kept cranking out gobs of power." PPl tend to forget things to prove there point

And how is that part relevant to this discussion?


I said hifonics amps are overrated (so what if I was off by how much). You said the XX line do their rated power. I posted a benchtest of an XX that was 8% overrated. Any more questions?

You dont even read what you post...the amp did its rated power..just not clean...your right 8%- 40% whats a few %. No more questions..

You really need to learn how amplifiers work before making these statements.......

If it was not "clean", it did not do it's rated power. Power ratings are taken at a maximum of 1% THD. That amp appeared to produce it's rated power at 2-5%, which is clipping.

If you crank the gain way up, an amp will appear to produce MUCH more than it actually can, since it's playing an almost fully clipped square wave.

Clipping is what happens when an amplifier is driven beyond it capabilities. If an amp does not produce a clean unclipped signal at it's rated power level, it is not rated accurately.

Ok will do...You need to learn Math and not to misquote...Im done.

well i will be powering three HD315 subs and the biggest i can do for a alt is 200 amps and that will be pushing it. so i need as much power as i can get but like i said i can only do 200 amps

Matt: Look into a Digital Designs Z1.... a used one in mint condition is about $900-$1000. They are not cheap, but they are one of the most efficient 12 volt amps I have ever seen. They do 4000+ watts on 12 volts.

will that amp be too much for a 200 amp alt?

HA! yeah, it will be, but then again...most amps that put out that much power would be too much for that alt. Although, it does help that it's really efficient.

Any amplifier big enough for three HD3 15"s is going to be pushing the limits with a 200 amp alt. The Z1 is highly efficient though, and I'll bet you could run 3000 watts (1000 to each sub) with daily music and not have too much voltage drop, if you get a big battery (i.e. Kinetik 2400 or similar)
