oo kumpletos recados yung manual hehehe  Grin Grin Grin

pinagawa ko yung pcb sa dating kasamahan ko sir
tapos 8 ohms lang din gamit ko na jbl noon
wala kasi ako nung original na speaker niya.
saka parang up to 6 ohms lang ata itong ic na ito
nde ako sure nde ko pa nakita specs nitong chip na ito.  Smiley

yes sir strictly 6 ohms lang pinakamababang impedance na kayang itulak ang mga STK

karaniwan kasi ng mga nagpapaayus ng component na may mga ganyang ic

nasaksakan ng 4 ohms, yun dale. libo nagastos hehehe
