Re: Speaker makes crackling noises...Need some advise?
First of all, an Alpine head unit should not be driven to volume level 25 if the internal amp is used. It introduces distortion at around 22.
But yes, it very well could be poor wiring. It could also be that the speaker is damaged due to clipping the shite out of it at volume level 25.
My guess would be a wiring problem, given the install shop.
