defakadef7 Posted September 28, 2016 Report Share Posted September 28, 2016 This month just keep getting worse......So earlier today i found out my subs were out of phase and fixed them when i got off work. (Separate post) After i fixed them, I turned on the car and now my speaker are give really high screeches. I couldn't even turn it past 19 without it screeching. So i pulled over in a parking lot and as soon as i turned my car off SCREEEECH. Soi turned my gain down on my 4 channel and it still did persisted. Next, i changed the setting on my lc7i and it fixed the screeching when im playing music but now my volume is lower. now i can turn it to 45 but it sounds like 27 before. But when i turn of the car no matter if the volume is on 0 it still SCREEECH. Here is a video of the sound (WARNING LOUD NOISE) https://youtu.be/gyRAq0ubUgI Please help Link to comment Share on other sites More sharing options...

Skullz Posted September 28, 2016 Report Share Posted September 28, 2016 Check everything you touched, you might have a wire with a single strand shorting out on something. Any time you have something unexpected happen after a change, you always want to change it back to see if it corrects the issue you have, and work your way to the cause of the problem. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
