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.

just hook it up and try it out that will tell you.

set gain low. the other is your filtering frequency as at what hertz you want to listen at switch threw them for your best sound.

Question makes no sense.

the shown photo is a bit confusing too me , clearly this is an automotive speaker , but in the photo there is clearly a home power cord shown , is this power cord connected anywhere on this speaker ? as if it is , id be afraid that amp has received home power and not car power , as the two are not the same and have tremendous differences and would be quite damaging to this amp possibly unrepairable damage

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.

Ohm's Law says watts / volts = amps, so 1000/12 is 83+change -- damn! I hope you have a big, phat alternator! So fuses have to be rated somewhat higher than device load, you need a 90 amp or 100 amp fuse -- what style I couldn't even begin to guess, normal automotive fuses don't go that high. If this is a new install, make sure your power wires are heavy enough to handle the load. A fuse's job is to blow before the wiring catches fire. The longer the wire is, the thicker it must be. Electrical fire is a catastrophe so make sure your wiring is adequate -- I know it's hard to believe but the power wire is actually more important than the speaker wire!
