We had an incident here on Cape Cod last month with the electric. The AC motor boated; turned on & off very rapidly, about 5 or 6 times in succession. Not even off long enough for a back up generator to turn on, and help.
All of my gear was perfect (some systems were even playing). One F113v2 wasn’t as lucky; it was producing a rather high pitched signal for a sub, at a fairly loud level. The sub was in standby mode.
JL Audio tech support was familiar with the issue; it was a Transistor and a few other components.
They had me measure the impedance of the driver, to verify it was ok. It measured 2.4 ohms (well in the safe zone)
I sent the Amp plate, and the internal crossover (requested by them) for warranty repair. I received it back in about a week, and all is fine once again.
JL does recommend keeping the sub on at all times, as opposed to signal sensing mode.
