[QUOTE="Rashaddd, post: 5434909, member: 592162"] Power = Voltage x Current Dropping voltage doesn't mean dropping power, so long as amperage increases. This is also what can cause amps to blow. For example, let's say you have an amp (we'll give it 100% efficiency), putting out 1kw. At 14v power input, this means the amps internals have to be able to handle about 70 amps of current. What happens when voltage drops to 10v? Well, either you lose power, and are now only getting about 700 watts max out of it, or you increase current to compensate, which means the amp will try to pull 100 amps. If you have proper fusing, your amp should be fine, and hopefully the fuse blows. If you don't, there's a good chance you'll see smoke out of it (even with proper fusing you may blow it) [/QUOTE]
