I recently installed a new Alpine HU and now I have static from the speakers. It gets worse when I use the power windows. I was wondering If I should reground the HU to something better than the wirirng harness ground. If so where is a good place?

 

I had the same problem i grounded mines straight to the battery

 

yep ur ground may be off, look fro and test new grounds and c if thats ur problem , id get humming in my speakers sometime , but thats my fault i may have shorted somthig when i didnt take out my fuse when messing with teh subs

 

also, if you have a sub in the back with an amp, run the power wire on one side of the car and the other wires to the other.
