Guys, tulungan niyo naman ako sa basics ng sound setup. Wala talaga ako alam. Where do you start? Do you start from the HU and build from there or do you start from the subwoofer and built from there?

Ano ba ang dapat hanapin ko when shopping for a HU? Is 50W per speaker enough for a CRV? I'm not looking for loud banging music, mas gusto ko clarity and no noise. It has to be able to play mp3 files as well.

P40k lang budget ko. Kailangan ko siguro: HU, 2 front speakers, 2 back speakers, 1 amp, and 1 sub. Do I need tweeters? Ano pa kailangan ko?
