    Need help with 4700uf 25v replacement in subwoofer

    Bought a cheap sub on marketplace for $20. Has two 4700uf 25v Jun Fu 85c rated caps. I've found several replacements for around $1 or 2 but what ripple current rating should I shoot for minimum? Also they have to be 16mm wide and a max of 30mm tall, lead spacing is 7.5mm and they are through hole.

    I am about to buy these just because they're cheap and 105c rated

    Edit: add some bad 22uf 25v Jun Fu's to the list as well

    i wouldnt bother,
    your not hitting the caps with high frequency's

    if you do replace them you need high ripple current handling.
