what causes the sub to make Popping noises?
So i have a alpine 12 type R 4 ohm and a alpine Mrd-605. My amp bass is turned all the way up and my h/u subwoofer is turned up to 12-15 (15 is max). My sub doesnt have a problem with popping if my component speakers(type S's) bass isnt turned up at all but when i have em turned to 6 or higher (10 is max) the sub makes popping noises. So im asking is why when i turn my speaker bass up it causes a popping noise from what I THINK is coming from my sub, when it hits the deep bass?
edit: it only pops when the volume is turned up past 14 or 15 with my speaker and sub bass turned up
