I got a pioneer CD 3 in my f150 and after i installed it, the sub woofer began to pop whenever i turned the car on. Any suggestions on how to fix this. Thanks

 

without knowing too much about your set up, i would suggest to look over every connection and make sure that none are loose, including the hookups on the subs themselves, and that everything is hooked up properly, every splice should have a butt-splice or some other crimped connector, pops and fuzz are usually due to feedback from loose connections, however, if everything checks out good, then i might consider getting an engine noise filter

hope this helps

 

Run a search on here for 5v Amp turn on's. Thatll take care of the pops.
