if one out of a 2 voice coil sub blows, can you tell it definitely? or do u have 2 really listen to hear it?

Question

i have a solobaric L5, and the other day, the CD is was playing sounded like it wasnt putting out quite as hard as usual. i changed the cd and it was back to normal, put the first cd back in and it was fine. so now i keep listening for it (hopefully it was all in my head), and i havent had another problem yet. so im wondering if one of the voice coils in the dual VC sub were blown or bad, would it be a significant difference, or just slightly less powerful? cause now im paranoid that i may not be able to hear it if it is bad. it runs off of a Bazooka 500w mono class D amp. and i was thinking maybe the amp got hot for a minute too (it was warm out and i had been playing it a while). im planning to put a Kicker 750.1 amp on it soon, so i was just asking yalls info on this. thanks

Answer 1

simply hook up the voice coils one at a time, if one fails to move the cone then you have a problem. If one did blow you have to remember that the impedance to the amp will be less so the amp will be putting out about half the power.

Answer 2

I too think amp got too hot and turn on protection ....
