Alpine HU vs. Pioneer HU. Ang panalo ng Alpine is that mas malinis siyang magfilter ng noise. Therefore mas malinis ang tunog. Kung if you are to compare naman with regards to features, actually halos same lang. Pinagkaiba lang is the price. Definitely mas mahal ang Alpine.

Yung supplier ng Alpine dito sa atin ay si Perfect Circle na nasa Banawe. Branch nila yung Autosport sa 3rd floor Mega Mall Bldg A. Hanapin nyo si Sol dun (although not sure if she is still working there). :-)

Hope this help.

God bless!!!
