Mga Bro, newbie here. I want to upgrade my car audio. Right now I have stock speakers and Sony Xplod HU. My car is Nissan Sentra 2007 gx model. Do you have any shops na ma rrecommend preferably makati or paranaque area?

Ang gusto ko sana yung very affordable sound "package" na since di ako masyado marunong sa car audio. I'm gearing towards a better sound quality, not necessarily "Boom Boom" basta malinis lang and buong buong na sounds.

Thanks mga Sirs!
