I've been researching car audio systems for over a decade, and Infinity is definitely a mid-to-high-end powerhouse in automotive sound. It's actually part of the same family as JBL and Harman Kardon – all brands under Harman International. You'll find it as original equipment in top-trim Nissan Teanas and some Infiniti models. Its signature characteristics include crystal-clear vocals and powerful yet non-fatiguing bass. While it can't match ultra-premium systems like Burmester, it's leagues ahead of standard paper cone speakers, especially when it comes to pop and rock music – the instrument separation is truly remarkable.

Last week, while helping my buddy upgrade his car audio, I had a chance to closely compare and realized Infinity is like a professional brand's trickle-down product. Their home audio systems are actually quite expensive, but when the technology trickles down to car audio, the value becomes excellent. What they excel at is the tweeter units - those aluminum diaphragm tweeters sound exceptionally crisp and clear. You can still hear the lyrics clearly even with windows down at highway speeds. The audio shop owner mentioned it doesn't require major wiring modifications, as the stock head unit drives them just fine, making it perfect for owners who don't want to go all-out with modifications.

Car modification enthusiasts are probably familiar with Infinity, a North American brand with solid technical foundations. In the automotive audio hierarchy, it ranks in the mid-to-high-end segment, excelling particularly in dynamic performance. When listening to metal music, the bass lines are especially punchy without becoming muddy. However, bass lovers might find it lacking in sheer power, as it emphasizes a more balanced three-frequency response. Commonly found as original equipment in vehicles priced around 300,000 RMB, a four-door speaker set can be installed later for just over 2,000 RMB.
