Swollen Capacitors

[Buttlice 10+ year member]

Hello,

The search has failed me!

I have a JBL GTO.1201.1 amp on a JBL P1222 with 4awg ixos wire. Just recently the sub blew. (AHHHHH!!!!). I noticed that there are 4 capacitors on the amp that are swollen. Would this be related to the sub blowing? I was told they swell over time, is this correct?

Also, I have the amp taken apart and have the serial numbers of all the caps. Would it be worth soldering on new caps or just get a new amp? If so, should i replace ALL the caps or just the ones that are swollen? Does that include those huge *** ones?

Thanks

I see this a lot on computer motherboards, the main capacitors swell and eventually pop. I don't know exactly why it happens, but it isn't uncommon. If you're handy enough with a soldering iron, and can find matching caps, I'd just replace all of them.

sounds more like a low voltage problem, not only that, crown's aren't made in china //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

getting the amp too hot is why they swell and will pop over time..
