Hopefully this is the correct place to post. I have a whole house audio amp with outdoor speakers as part of the setup. Lightening struck near the house last month and apparently sent a surge through the speaker lines back to the amp, blowing those two channels.
Does anyone have any info on surge protection for outdoor lines? I looked on line and found something from Grommes and some other folks but would appreciate some practical information. Tangentially related, the same surge blew out my sprinkler controller and pool controller as well!
