BTW, a general question about speakers.
What is most likely to cause static?
I have two J&M handlebar speakers connected to a Garmin 590 navkit and media player.
Each speaker has a preamplifier and the set comes with a noise suppressor.
The wiring is soldered at various places and the set intermittently produces static.
Thought I'd ask the question here and look for the obvious before taking everything apart.
TIA

In my experience it's usually a poor ground.
