HI ! I'm leonardo from
If it is burning up resistors you have a power problem. honestly if it does this i would not invest the money into it i woud get another amp by the time it is repaired it will cost almost as much as a new amp. but if you still wanna do it id look threw china manufactures like Alibaba.
What is this ? On the back of Power Acoustik 500w subwoofer
Sub-woofers work on a low hertz as per audio. You have a built-in amp that has a crossover that separates frequencies under 100 Hz. Typical Hertz range is between 20-60. Since you have a built-in amp the black rectangle is a heat sink which helps to dissipate heat away from the internal components and also seconds as a cover to keep debris and other foreign objects from getting to the amp and burning it out.
Hope this helps.
