radio speaker static
Recently I started getting noise thru one of my overhead speakers as the engine revs increase when accelerating. Not a problem if just cruising.It occurs even with the radio off and volume at zero. Any ideas to correct would be greatly appreciated. TIA!

That sounds like an alternator whine. If it just started, you may be repairing or replacing the alternator or regulator before long. It could also be a loose connection in the charging circuit and most probably on the negative side. I'd start by checking all the grounds from the engine/alternator to the frame.

I run into this all the time in car audio. usually its a ground loop issue (lots of grounds/poor grounds). does this happen while listening to the radio or from another source? is there a separate amp in the mix? you may need a ground loop isolator. they come in both RCA connections and 3.5mm connections and antenna. very inexpensive.

Engine noise
Noise introduced through the power and ground wires connected to your receiver is called engine noise (sometimes referred to as “backway noise”). If engine noise is your culprit, you may hear a whining or clicking sound. Its pitch will usually vary with engine speed.
If this is the case, you can install an alternator noise filter on the power line between the battery and the alternator to minimize the problem. You can also install a noise filter on the receiver's power lead to cut down on signal pollution (American International's S15A (15-amp, 250-watt) or S25A (25-amp, 350-watt) filters, for example). Most often, however, backway noise comes from a loose or intermittent ground connection.

that would be my first go to if you are not comfortable playing with wires. im not sure that the dealer or manufacturer could resolve this issue properly. the car audio guys do this day in and day out. you will want one of the independent locations, not something like bestbuy. read reviews of your local shops. there are a lot of hacks out there.

Remove the power supplying the radio and hook it to a separate battery if you happen to have one. That way you can isolate it to coming from the power from your RV or something getting radiated in.
Personally, most audio guys just throw on bandaids(line filter) rather than actually fixing the cause of the problem. There could be be many causes from an alternator that has a blown diode to a bad spark plug wire or other ignition issues.

Well, then you don't have ignition or spark plugs...
Now, because it is only on one side, I am suspecting there's something in the wiring to the speaker, or a problem with the speaker itself. I would start with swapping the speakers on the back of the the unit and see if the problem moves or not...
