JL Audio F110 Loud pop when pc unplugged ?

I would not unplug the unit unless an electrical storm is coming, then make sure the unit is off and not in standby, and don't unplug it until a few minutes after it's been turned off, that has worked for me.

How do you have them connected? An IC to each one, or an IC to just 1 and make the other a slave? Also, balanced or se.? You can also try lowering the volume on the subs all the way and then unplug them.

I like to thank you all for your responses.

Whenever I planned to do some work with the subs, I turn off the front ON/OFF switch overnight allowing the caps to discharge.

I had to unplug the power cords a few time because of re-postion and pc replacement.

An IEC to each sub. Balanced feed and no slave. The subs are powered down before I unplug the pc and volume setting does not make any difference.

My next test is to allow the discharge time for 40-50 hours before unplugging, perhaps overnight is not long enough.
I will post the results.

You might want to call them up or email them, overnight should be plenty of time.

mine do it to FWIW. i generally never unplug, unless leaving town.
