Yes the sub is wired correctly i have just swapped out the old amp with the new one... Its very odd.. And yes the crackle and ppp from the subwoofer is only when the headunit is on.. If i put it at 0 volume.. U can hear a scratching/crackling/poping sound from the subwoofer..
Also i cranked up the volume earlier and my amplifier went into protective mode
When i started the car back up it all worked fine but i havent cranked up the volume since. I have just gone and disconnected it all as i dont think something is right with the wiring i dont want to fuse or blow anything
Also i have tried two different subwoofers both are doing the same thing.
Any ideas on where i should start to check?
