I have an '01 accord coupe with tweeters in the front, 6.5's in the doors, 6x9's in the rear and 2 12's in the trunk. I replaced the OEM radio with my kenwood head unit and ever since there has been a scratching noise coming from the speakers. At first I thought the tweeters were blown so I took those out but now it is coming from the rear speakers. Bad wiring? Tweeters blown on the 6x9? Any help is appreciated thank you

 

When do you hear the scratching noise? Loud volumes? Low volumes?

So you saying it started in the front, then moved to the back?

 

Yeah at first I only heard it coming from the tweeters, but it may have been coming from the back as well at the same time. Also when I accelerate, as my engine goes to higher RPMs, the noise gets louder as well. I can hear the scratching only at low volumes because the sound of the music covers it up at higher levels.

 

Do you have an amp? So far it sounds like a grounding problem. Check the ground connections on your deck, and also if you have an amp.

 

i second the idea of having a bad ground

 

yah im guessing bad ground ...try re grounding it sand the paint of the point where your trying to ground it

 

Yeah I have a 4 channel MTX underneath the passenger seat, I'll check the ground, thanks for the help, hopefully it will remedy the problem

 

also since you have a 4ch, it could be your rca's. what kind are you using and how are they ran and also how is the power ran too.
