hey fellas, first post on here but i just changed my front and rear door speakers in my 99 dodge ram 1500.(used to have the infinity system). now there is a loud sqealing noise coming from speakers when ever i hit the gas. same deck ive had in for 2 years now. only changed the front and rear door speakers. any feedback would be greatly appreciated. thanks corey

 

Did you have the "amplifier on each speaker" system? If so, you could try and shut down the "choke relay" which used to power each individual amp, by cutting the output signal wire on the deck. Also, if you had the " amplifier in each speaker system", did you use the correct sound wires to the speaker, or did you use the voltage (power) wire that used to feed the amps? Other than that, shielding could be your issue.
