JL Audio F113 --- Loud Buzz --- ??? --- Bizzarre

I have two F113's in my 2 channel system. I keep them in the Auto Mode so they turn on when they sense a signal. All of a sudden one starts blurting out this high pitched rumble that ends up stuttering loudly. Turn the power switch to off and obviously it stops. Turn it back on and it emmits the same sound and it doesn't stop. I have tried other power recepticles, unhooking IC's that run to the pre amp. No success ......... what the **** happened ???? Bizzarre ????

Both my fathom f113 subs were severely damaged after
a power failure/surge. JL Audio needed to replace the
amplifiers and wiring. As JL Audio suggested I'm now
using Surg-x surge protection units with each sub.
JL Audio honored the warranty but the repair took almost
a month. Good Luck!

If you had a surge, I agree with Elizabeth- you probably fried one of the modules in the Class D internal amplifier. I had a lightning strike near my home last spring and it cooked a Rowland Class D amp that was run via a surge protector. The best thing to do in a storm is UNPLUG! Don't bank on a surge protector. Good luck packing up that F113. That thing weighs close to 100 pounds. My F112 came with a fault in the ARO LED, but I said to hell with it- it works, I don't need the green light to go on to tell me it works, and I'm not packing that beast up unless it flat out fails completely.
