No need to change the OEM head unit as long it has an RCA audio output at the back of the stereo unit. With that budget, you could choose a lot of options for amps/ speaker set or subwoofer with built in amplifier ( V12 brand).

Mag inquire ka muna sa mga nag install ng audio set para may idea ka regarding the price of budget set up kung anong mga brand ang ilalagay at pagisipan mo munang mabuti kung ano gusto mong setup para sa kotse mo at hindi ka palit ng palit ganyan ang nangyayari sa baguhan nag uumpisa pa lang mahilig sa sound system ng sasakyan.
