After I changed the speakers in my car the speakers are whining
I replaced a set of JL Audio component speakers with a pair of Polk component speakers and now I have a whine from my speakers that gets louder as the engines rev's up. There are 2 amps in the car that were not changed. I also used the wiring from the original JL speakers. Does anyone have any ideas on what the problem is? I had no problems before the speaker swap.
