I have boston acoustic 6x9 speakers in my rear deck of my honda civic and they make a crackling sound when music is turned up too loud or hit bass notes. The crackling sometimes is there and sometimes just goes away and the speakers sound great! when i hold the wire from the tweeter to the midbass the sound mostly goes away. Sometimes the sound is way louder than other times. Also the sound is usually out of the right speaker but the left speaker sometimes also has a crackling to it. I have no clue what is wrong. Any help is welcome.
