ok heres a post from another website of a guy talking about a vlx-400 amp i beleive by usa amps or some companny like that, tell me what yall think. The VLX-400 is the largest amp in the world (at the time of production 1999), measuring in at 44 inches long, power is fed my four 8 gauge power and four 8 gauge ground wires, and speaker wires are four 8 gauge wires, all coming out of the amp for hard wire. With a power consumption of 400 amps at 1 ohm at 12 volts, this amp is capable of 1/4 ohm mono, and with every volt increase above 12 volts, these amps will produce aproximately 30% more power, so at 14 volts the actual power at 1 ohm mono is 3840 RMS watts, 7680 @ 0.5 ohm mono, and 15,360 RMS watts @ 0.25 ohm mono Most of you may call BS, but for those that know US Amps, they are a power house!! Go to the12volt.com and ask them about the old school US Amps, the famous VLX-400 and see what they say!!
heres my 3 cents I remember those amps, never installed one of the biggies though. I seen a smaller version of one at CES back in about 1996, they "impressed" everyone by hooking up the speaker leads to a pencil and sending some signal through the pencil led, it would catch fire and make smoke.....whoopee. They were an OK amp, they werent an old Orion or anything like that, but they did OK. Now this 15 bazillion watt claim could be true. For a few seconds..... .25 ohms is a nats butt away from dead shorting speaker wires... And even if it did this power at this impedance, what happens to the dampning factor? I am willing to bet it is non existant. As for the various forms of distortion, ill bet one US dollar (which aint owrth the paper its printed on) that its in the double digits. I bet when that amp starts a cascade failure in its outputs and power supply it will make for one helluva smoke show, without the pencil!!! lol
