I'm curious what types of installs in particular are important to disconnect the battery. All of the professional websites of course suggest always disconnecting for any install or modification of any kind of anything speaker/sub/amp/electrical related. I recently did the big 3 and I have several connections on my battery terminals that make it difficult to disconnect and reconnect all of the time.
Have you guys ever suffered any bad effects from skipping this step for installs? What is the main thing to look out for if you don't disconnect? Just curious.. thanks
