I have a hum in only my right speakers with RPM increase. When the car is in neutral there is no hum. Does anyone know how to alleviate this ?

Sounds like the speaker is picking up engine noise, which most likely is coming from a power wire. Did you add aftermarket amp? In any case, there are several things you can try.

1. use a better insulated wire
2. re-rout the wire to avoid any power wire
3. re-ground the wire, using a better wire and/or try different location
4. use a noise isolator

Good luck!
