[QUOTE="bbeljefe, post: 8390907, member: 655960"] It isn't hit or miss as that would indicate the possibility that some amps have the necessary protection and some don't. And to my knowledge, that's not the case. The thing is, we know that the lack of vibration protection is a problem. We also know that [I]if[/I] the amplifier is subjected to vibration, it will at some point fail. When that will happen is entirely subject to a number of factors, including but not limited to: 1) The intensity of the vibration. 2) The frequency (in Hertz) of the vibration. 3) The frequency (in time) of the vibration. Everything has an Fs (resonance frequency) and the boards in these amps are no exception. My guess would be that subjecting them to their Fs is probably the quickest path to failure but, sufficiently high levels of vibration at other frequencies can also cause failure, albeit at differing periods of time. So in the end, no one can predict how quickly they will fail or at which frequency, without a significant amount of research... which isn't something that's really warranted. What that means for your buddy's amp is that no one knows when it will fail but there is a very high probability that it will. [/QUOTE]
