[QUOTE=threadstone;2385269]Pwede po bang ma-acchieve yung sound set up na para kang nakikinig sa I-phone or ipad? yung buong buo ang tunog and tamang tama lang ang base.
Ang stock unit ko is AVT and sa mga nabasa ko, kailangan palitan yung HU to get a nice sound set up.
Ang worry ko lang is mawawala yung built-in GPS ko which I really enjoy.
Ano po bang HU ang available na hindi masyadong mahal and me built-in GPS and at the same time will give you a good sound output like Pioneer.


If you want to retain your head unit, then the 1st thing to do is change the stock oem speakers. Look for a low wattage high sensitivity type. To add more bass that will blend w/ head unit powered speakers, install a under the seat type subwoofers. AVT sells this kind of active subs. You might want to deaden your doors, while you're at it.

Adding a DSP, should be the last option if you are still not satisfied with the outcome.
