I got my new Xtrail CVT 4x2 and it only comes with 4 speakers against the 6 speakers of the 4x4 unit. Where and what brand is good to add the 2 tweeters at the front? Sayang kasi yun speaker space sa harap. The stock speakers are good enough for me in the meantime so I just want to make it a 6 speaker setup. I'm planning to ask the casa if they sell tweeters but there might be better and cheaper alternatives elsewhere.
Just buy whatever separates your money can buy. Just don't buy speakers more than 7k since you wouldn't appreciate them without an external amplifier. For what it's worth, find high-sensitivity speakers like Cadence ZRS.
