Ok so i have a FI BL 15 Fully loaded powered by a Sundown SAZ-1500d.

Ok so anyway when i play some music loud i hear some weird sound like the sub it bottoming out but i know its not becuase its not moving enough to bottom out.

Wires crossed? Whats the gain at?

Gain is a little lower then half way and i don't think they are crossed.

K then it may be the signal cables. They might be bad.

Then after you think you fixed any, check again.

Check the dust cap also.

If it came even a little unglued it can make a nasty sound.
