Question about Boss RT-1045 Car Audio Amplifier
Those 2 capacitors are definitely blown.
if you look on the side there should be a reference, something like 12v 400uf or pf.
do a google search for that capacity, they shouldn't cost too much (probably less that $1 each but I'm not sure as we buy in bulk).
Just remember though that if you do replace them, make sure they are polarized.. This means they have a Positive (+) and negative (-) and make sure that you position them to the correct polarity on the pcb or they will blow again, so make sure you put the cover back on or you could get a face-full of electrolyte.
Also you have to remember that they may not be the only faulty parts, something must have caused them to blow in the first place, that could be a few things, from overload (high voltage or hight current), extended use at high volume or other faulty components.

Hello Sir, hi, as I see it, on the first picture with the whole board seen, you need to replace the two medium size capacitors on the rigth side and on the bottom there are two large capacitors which are bulging, you need to replace them too.
Now the question is, why did those capacitors blew up?, A capacitor blows up if there are too much current flowing on it, these over current condition MAY be caused by a those power amplifier ICs, on the sides, those black ones mounted on the heatsink. you need them checked for shorts or overheating.
WHat you need to do. Replace first the four mentioned capacitors, then test the unit. If it works then Good. if not, you need to check those power amps ICs.
