Identify crud on amp board?

[OKAY]

Kicker KX350.4 has been working just fine. Today it rained, water leaked into my van, some water splashed onto the amp. Its happened before one time without affecting the amp. Amp is covered pretty well.

So to make sure their was no water i see this old looking crud on looks like a few resisters and near the fets.

Anyone know what it coukd be? Looks old. I bought the amp used a month ago and looks like its cosmetically, hardly been used.

Looks like the crud thats left on batteries when you leave them in something for too long. Maybe thatll give you a lead to go on

you sure its not coming out of a nearby capacitor or other component?

considering the nearby board is clean it looks like some substance got on there and baked for a while and dried out white

edit; just saw its multiple fets, definitely overheated. looks like one of the bias capacitors?(white things) are actually burned.

You're referring to the rectangular white block with the letter 'J' on it? Theirs 2 spot like this. The bottom one has no white capacitor. Or which ones?

Is it unusual for the amp to play normal like it is? What may happen if i keep playing? Nothing or a high risk of something happening?

I see glue around the large caps if thats glue.

But i also see something of a darkish color built up on the side of this white rectangular block that blends into the white crud. (not visible in the pic)

I BLEW them up.

-->> I see what looks like a brown burn mark on thr bottom corner of that white block.

it's not unusual i guess because ive had an amp with a gate resistor overheat but not to the extent im seeing on that amp. it's hard to say how reliable it is, likely not any more than if it werent all nasty looking

Its back in my van running good, again. No wonder i got a great deal on it..

Gotta open every amp up buying locally it seems. Time to resell it before it pops. Come come lowballers...weryaat!?
