Yes. Somewhere lang yun fader settings sa HU.. konting kalikot lang
I think the correct term is that "fade" refers to front and back while "balance" refers to left and right. Di lang sure

Okay lang yan. Most of us aren't fussy with HUs since the power can easily be compensated by an amplifier. Since you plan on powering it just using the HU, make sure that the HUs can support the RMS power of the speakers. Aside from that, I might recommend:
1. Ditch the rear speakers. You won't be needing good sound at the back if you're in front. Fade output to the front. If you're ferrying passengers and you don't want them to complain, just stock speakers would do fine.
2. Rather than going for a monoblock immediately, go for a 4-ch amplifier first. That way you can have some headroom just in case you plan on upgrading your speakers.
