WOW "ULTRA CLASS D" So maybe I am a total skeptic when any company comes forward with first off a new version of "digital" technology. What "Digital" means is the power supply will shut down certain output components when they do not have a signal to reproduce and turn them on when needed, thus creating less heat therefor you will have better efficency. How much can you change about that?? Not to mention the outrageous claims of RMS wattage... Now I am not saying that these amps will not do this power, well I guess that is what I am saying. After testing god knows how many amps I have never found an amp that has done the RMS power the manufacturer has claimed. The closest I have ever seen an amp come is the believe it or not Power Acoustik LT 620/2. They claim 620 wrms at 4 ohm at 12.8 volt, we tested one for fun one day and got 596 wrms at 2 ohm reactive with 13.9 volts in. Not to bad for under $300. Now I will give it the benefit of the doubt and say that these figures given on the Hifonics amps may be attainable but at some ridiculously low non reactive load in a testing facility with a lightning strike for voltage. I dont want it to sound like I am hating on Hifonics which I am not, I am just making a statement that the ratings from all companies on amps that I have tested are are not right. Visonik claims 4000RMS at 4 ohm on the V4000XD, not even close at 4 ohm and even with over 17 volts in. This post may come back and bite me in the A$$ later and I hope it does, but in my opinion I would say you might get 5000RMS with 17+ volts, with 30 batteries so there is tonnes of amperage available, and at like 0.25 ohm with a maximum impedance rise of like 0.5 ohm out of the claimed 10K beast. |
