[QUOTE="CarAudioAddict, post: 94935, member: 545743"] What does overvoltage cause? More current flow. What does more current flow cause HEAT!!!!! Maybe not all companies do this, but many do. Say you take a pyramid amp. It has 105C caps in it. That means that the cap will fail if its temp reaches 105 degrees celsius. Now which would take longer to reach this temperature an amp at room temp. or an amp at -200 degrees. You don't need to be a scientist to figure that out. I happen to know that many mosfets used in car-audio can handle much more voltage than just the 12-14.4V that your car uses. Top name brands use fets that can handle over 100 volts. This is to prevent damage from voltage spikes that ALL alternators put out. Alternators don't put out a constant 14.4V. The voltage fluctuates and sometimes spikes to 100's of volts. These spikes only last a few nanoseconds but they are there. If Amp A had Fets that could only handle 14.4V then as soon as you start the engine in the vehicle that amp is TOAST. The most common time for these spikes is at Start. [/QUOTE]
