I'd appreciate any comments or feedback on this head unit. It's the stock HU on the Grand Vitara. 2-din 45x4.

Tunog lata yung sounds nung GV. Was thinking about making some improvements with the speakers, but my installer tells me to start with the HU first. According to him, changing it to at least a DEH-P7450MP should improve the sound quality. After that, then we start experimenting with the speakers.

Tama ba? Or is he taking me for a ride?
