audio set-up for beginners [continued]

[Sleepcare]

got it sir. pag nag coax speakers na ako, does it mean I need to add rear speakers pa? or no need na?

as for the amplifier, is it needed if nag upgrade ako to coax na 4 inches parin? most likely hindi ko na bubutasan door cards since this will just be a very basic upgrade lang

sorry. totally noob when it comes to audio set up

It really depends sayo if you'll want to add rear speakers. Please check if same size lang yung coax sa front and provision sa rear. Kung sakto, lipat nalang sa rear yung stock front speakers para hindi sayang and it will act as a "filler" sa cabin ng sound.

I think that you do not need the amp if that would be the case. Kakayanin naman ng head unit.

BTW, are you gonna use the stock head unit or papalitan mo din along the way or napalitan mo na?
