Check out my mono subwoofer amp repair.

Soo ive got a Hifonics Brutus 2000w amp and due to my lazy wiring in the last car i had this in i shorted out the power wire to the ground on the front connections and i popped 2 capacitors inside. i like to try and fix stuff so i figured id give it a shot cost me $10 for 4 caps from china on ebay, i replaced the faulty ones, and now just gotta find time to install the amp and test it out. this is my first time with this kind of a job so let me know what you guys think and if anyone has any experience with this stuff let me know.

i couldnt get access to the underside of the board to desolder the old caps the right way so i just used a dremel and gutted em as far as i could. i had a real PIA time trying to get the solder to grab the connections of the board, but it eveantually worked and it seems pretty stiff im gonna give it a shot.

can anyone recommend a good fuse size to use with this.
i have 0 gauge wire and 2 Kicker 12" L5 Speakers as my setup.

first pic is a shot of the caps i used
second is the amp it self,
and third is where i made the amateur repairs.

Size of fuse isn't really an issue, I usually use the same size of the fuse as all of the ones inside the amp together. Its mainly there as a safety precaution incase the power grounds out. My amp has 4 20AMP fuses so I would use an 80-100 amp fuse, since the amplifier should never draw that much anyways.

Also for future reference on soldering you take the board out and remove the solder from the back of the board and the caps come off you don't cut them with a dremel. Plus that makes the holes open for you to put the new leads into and solder them on the back as well.

i wasn't able to take the board out and de-solder the parts, that would have been the right way to do things, you are correct sir.
