hi Guys,
i have this running in my truck for about 6+ years
still working perfect, but i randomly decided to open it to give a dusting, and found this: the big capacitors ( few of them have little bulge )
expecting them to blow soon?
should i replace them to prevent it dying ?
its pushing 2 x 12" ss t7, ported, and its awesome .

Are you sure they are bulged or is it just the plastic cap?
How do they feel if you press with your finger?
If aluminum can is bulged I would replace them.

ty for reply,
tbh , i didnt press on caps to see if solid bulge or just plastic, i will openit again in couple hrs and get back .ty.

hi, so i opened it again, no side bulging at all, the top of the bulged ones is definitely solid as i cannot push the plastic tops in at all.
It’s a common problem in these amps .
I have the same amp here same problem .
I replaced the caps and checked everything over the new caps lasted about a month and same issue again .

You need to drive the amp hard while watching the rail voltage to confirm that the rail voltage never exceeds the working voltage for the capacitors.
Do the caps heat up when the amp is driven hard on the bench?

Hmm. Well they are some China brand caps and I'm sure they would fail in many amps.
Check voltage as others say. And keep in mind that overvoltage could also damage other components than caps.
As it is a bridged stereo amp you should not have any rail-pumping.
But get some quality caps and maybe 160V ones.
In an SMPS capacitance hardly matters. It is max. ripple current that matters.
