I have 2 new 6.5's in my door panels but the right front speaker starts popping pretty heavily if i turn the volume up to about 60% or beyond. I'm fairly certain theres nothing wrong with the speaker because its brand new but mainly because i had the same exact problem with the stock right front speaker. I can max out the volume on all the other speakers with virtually no distortion or "popping" at all. My HU is a Pioneer DEH-P6700mp. Can anyone tell me what my problem might be and how i should go about fixing it?
