Gen 3 Liberty

[B4_sonic]

Okay I've upgraded my stereo and speakers in my b4 and since doing it I've noticed I've got a whine coming from my front passenger speaker & tweeter and gets louder when the revs go up. I'm still running the factory amp.

Anyway to fix this annoying issue

Sounds like an earthing/ground problem. Check your chassis connections, if its screwed onto paint it may help to give it a clean/scratch it up a bit so the paibt isnt hindering the connection. Might pay to have a look at the earths on the HU also.
