    Awesome video, I have a similar question, my amp cuts out when the speakers are at a certain volume, that's right, understood its to protect the speakers, but does that mean when the amp cuts out, that's the loudest the speakers can go? if so, how does the amp determine how loud the speakers can go? because I had the speakers connected straight to the radio and it went louder, than via the amp

    So I bought a stereo from a friend which was a prime 1000.1 amp and two jl w6v2's 12". Well I never did take the subs out the box to see how the voice coils were wired. Well The w6's are dual 4ohm and they were wired series which would equal 16 ohm final at the amp. My question is could that high of resistance kill my amp? Cause I was playing it for 2 hours straight and it went into protect and hasn't worked since.
