Hello,
i opened up a poppulse t-150 to check a switch and saw that inside its used to large capacitors 8200uf labeled ALPINE (The same logo as the car audio company),never seen these before ,upon a google search i found the advert from audiophonics from where i purchased the amp and they described it as ALPINE for AUDIO from ELNA.
Never heard of these before ,are they any good ?
Of course the amp plays extremely well as is ,just asking about it because my initial though was they maybe source a bulk supply from somewhere and installed these.How good are these ?

ELNA in general - gives me a good feeling. I like the brand and their products and quality. The shrink wrap - may suggest that it is indeed an ELNA, because the color scheme looks familiar.
So the more interesting question would rather be: Are these capacitors really a product of ELNA, or some fake copy-cat alternative. What worries me a bit are the "looks" of the unconventional pressure-release pattern on the top of the aluminum can. Looks ... different.
Hey, but then again, if the amp works and sounds good - do not fix it.
If it is a class D device, then the more I would not fiddle with exchanging capacitors in there, because class D imposes some high demands upon capacitors, in terms of certain parameters, properties (high frequency performance, for example). I believe that it is not an easy and self-evident case of replacing such components in such constructs, based solely on the "uF" and "voltage" alone.
That is my opinion. Other opinions may differ.

Its Tripath 2022 with an LM4562 ,its plays extremely well ,better then an older mark levinson monoblock i had ,it drives a a pair of LS3/5a and Cambridge audio tl200 (rebuilt) exceptional well.
My though is that these are ELNA propably made for an Alpine amplifier.
After all their new amps are d-class.

If you look at the top, these are real ELNA´s.
As alou wrote, custom made for Alpine. Nothing to worry about.
