Weird Popping Noise *Repost*

[Mike J]

Well I have 2 12" Polk/MOMOs, an Alpine CDA-7875 and an Autotek MX-1300. Im running the amp at like 380 Watts x2 at 4 ohms. One of my MOMOs makes a weird popping noise. Even when I take it out of the box and knock on it, it makes a weird noise. The other one doesnt do this. My box is sealed and there arent any holes and it. I bought this amp at a "discount site" and i dont know what to do. Please help me.
