either bottoming out from clipping that small amp or maybe lead slap

The coil might be misaligned.

maybe just mechanical noise? give it more watts

maybe you are trying to power a 1kw rms woofer with 100wrms and clipping the p*ss out of it....

don't try to make a sub pound when you dont have enough power to do it.

Yeah My bet is you are sending the sub a clipped signal. What is the gain set at?

ya it was the amp that was doing it. i had on my home system. but i put it on my friends amp and it was fine.
