Hi I have an Alpine mrv f300 on the bench.
The amp switches from blue led to red when remote is applied.
I found a shorted 47uf capacitor E3701
After removing the cap the amp powers up normally.
I replaced E3701 and it immediately expanded and went up in smoke.
Attached are pics of the cap location and associated circuit, amp is 4ch digital.
What could be causing the capacitors to fail?
Thanks in advance

On this cap and the corresponding cap for another channel, what sort of signal do you see on each of the terminals?
Square wave, DC, other?
