Default Home home or pop pop noise from sub

I got an end-product sub. However, how it got loud LEF, besides the bom bom bom sound that I like, it noticed that it also produced "home home home" or "pop pop pop"noise from the vibrated sub cup. Is that I could overcome this by putting a low or high pass filter between the pre amp and the sub to filter those low frequency noise??

I have also been told that it may be the problem of power. Someone suggest me to install a 1000W isolation transformer to provide high stable power to the sub. If the sub could not get enough power, the sub cup will vibrate or distorted from LEF received! Any comments?? Thanks in advance!

My sub got phase reverse, volume and frequency adjust knoks!
