    Only at louder volumes? Baka stock head unit can't output enough power.

    bago magpalit, ganyan na ba?
    o, nag-umpisa lang pagkatapos mapalitan?

    kung pagkatapos, my simplistic mind would suspect loose connection.

    You need an amp pag ganun but you'll need to confirm.

    the stock HU normally can power the speakers at decent volume without external amp. but yes, confirm niya muna sa installer baka lang may isyu sa connection.

    When you get back to your installer tell them to check the ground of the HU.
