Re: my new id max 12" d4 making poping noise
should have broken it in first. sure your box is absolutely sealed tight and more specifically the sub is in tight with no leaks around it? mine made a funny sound along with the bass at high volumes until i siliconed it in the box. put in on a smaller amp with the gain down and run it outside the box and see if you can see the the tensil slapping. the leads are woven in the spider but there is enough of it coming from the tensil leads for it to be hitting the cone
