Crumb ,,,,,,,
the 180 performance series amp should be pretty splash resistant and also the entire pcb is con-formal coated at the factory during assembly ,,,,,,
the front vent on the new Harleys, allows the water to just poor into the inside of the fairing when the bike is washed ,,,,,,, but the J&M amps and splash shields usually do a good job dealer with the water ,,,,,
have you had any more issues with the system since it dried out ? ,,,,,
