Cockpit stereo speaker covers

[Gshenry53]

I just bought a pair of 7.7" JL Marine cockpit stereo speakers. They are made to withstand the environment, but caution that the cone membrane will not withstand direct high pressure water spray, which is a hazard that I fear mine could easily suffer. Andromeda is often washed in my absence, the dock water pressure varies, and is often extremely high. No way can I trust that those folk who may wash Andromeda will be aware, be careful and not blast a hole in the membrane.
It seems to me that these speakers should have a cover to protect them when not in use, maybe like the close fitting plastic cover that snaps over my Raymarine instrument displays, but I find no such product, reference, or discussion of this matter after extensive googling.
Anyone have any ideas or suggestions?

Mine are covered with simple sunbrella and snaps, eventually UV degrades everything, keeping anything under cover will make it last longer, if they cut sunbrella with a pressure washer, you sure don't want them washing your boat.
