i have 4 brand new in box . was going to go spl but changed my mind. $950 each or all 4 $3600.
Sorry, I have you confused with someone I spoke to in Salisbury that is a Critical Mass dealer. Your screen name looks familiar.1st i dont have a store. i am a consomer i bought a product that im not going to use i thought i would sell them on hear. i guess i was wrong asuming that i could give someone on here a great deal on a even greater product. i could always photshop whatever pics would make you happy but what does that prove?how bout you show me pics of your money! lol anybody that is actually intrested feel free to send me a message to every one else thanks for a warm welcome to a new member.

This means that if we are using a typical 4 ohm speaker, its impedance may drop to say 1.5 ohms at some frequency. If we have a 50 watt per channel amplifier this requires 14.14 volts to be developed across the load (speaker). So with a 4 ohm load, the current is 14.14/4 = 3.53 amps RMS or 5A peak. With a 1.5 ohm load it is 9.42 amps RMS or 13.32A peak. So in order for our amplifier to remain in pure class A (assuming the typical 4 ohm speaker goes to 1.5 ohms) it must idle at 9.42 amps RMS PER CHANNEL.Let’s see how the numbers turn out. The 50 watt amplifier runs off supply rails of about +/-25 volts (let’s also assume that this is regulated). The wattage at idle is 13.32 x 50 = 666 watts per channel. This is a total of 1332 watts of heat when the amplifier is just sitting around doing nothing! Let us compare this to if the amplifier ONLY had to drive a 4 ohm load the dissipation would be 5 x 50 = 250 watts per channel and 500 watts total, still not an insignificant amount of heat.
Any company who claims to have a pure class A amplifier (of reasonable power output and I do not mean 3 watts per channel) for the automobile is simply not telling the consumer the truth.
Don't know about the fuel, but good info. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifJust to add more fuel to the fire...
Supporting the comment made by squeak, critical mass amplifiers are NOT pure class A. At most they are class A for the first few watts then switch over...
