... I'm worriesd about my upgrade caps because my brother refuses to take it easy on my amp. You see, I only used excess XO (Solen & MusiCaps & Dayton) capacitors since I don't crank on my stereo. But my brother isn't happy until he cranks it upto half-way, insisting that it only opens up @ that point. I'm not only concerned about being evicted#, but I'm worried that my caps aren't designed to handle that much power.#- Which he's already prepositioning the sole blame on my stereo DIY subwoofers capable of subsonics that I play Hard Rock @ 60-65dBs. Not the fact he constantly cranks them & the rest of my system upto 90-100dBs playing dentist music. IMHO, it's oxymoronic. I liken it to my childhood when he'd bully off my stuff to BLAST easy listening. Talk about head aches. That's one way to stop me from doing homework.
(1) Ask your bro to leave your amp alone...get his own stuff... and let his own gear "opens" up his mind. He'll notice the difference halfway down his life.heee....heee.(2) Ask him to leave you and your gear alone. In other words tell him to find another places ;->

for reasons I'd rather not get into, it's not a "real" option.
Good grades ofcrossover caps are designed to handle lots of current.I have seen decent grades of metallized mylar caps get melted down due to heat from current flow, because they could not handle the current long term.
Met. PP caps of a good quality should be OK for power supply use, they ARE exposed to the ripple current of the PS, and since they are smaller than the electrolytics, they will be exposed to the entire ripple current, and as such must be able to handle it. SHould not be a problem, but I would not use anything less than quality PP in this position anyway.

Like I said, I'm using the extraneous XO caps hanging around from tweaking old DIY speaker projects.Dayton non-L film & foils
Solen PP & foil
MusiCaps

It would be a rare case of a crossover grade PP that did not have sufficinet voltage rating to handle a SS power supply.The surest thing is to look on the caps, they almost all have a rated voltage, adn the ones in the PS will have a rated voltage as well. If the xover caps meet ore xceed the rated voltage, no problem.
Jon Risch
It's typically excess voltage that will blow up capacitors, and this is almost never a consideration for signal-level applications since the voltages involved are ususlly small compared to the voltage rating of the capacitor. If you are talking about power supply caps, they typically see the same voltage regardless of the volume level, so cranking up the volume will not put significantly more stress on the capacitors. I really don't think you need to wory about damaging capacitors with excess volume - speakers may be another story....
I didn't know whether the increased charge flux would significantly degrade them.
No dude, no worries regarding charge flux. It's totally out of the domain as long as you have installed a capacitor with very conservative voltage ratings.Quest
