Hyundai XG350 Speaker FAQ

Which speakers should I replace first in my Hyundai XG350 for the biggest sound improvement?

Replace the front door 6.5 inch speakers first. These handle most of your music's midrange and bass content - around 80Hz to 4kHz typically. The front soundstage creates the primary listening experience in your XG350. Rear deck speakers mainly provide fill, though those 6x9s do move more air. The 0.75 inch tweeters might seem important but they're usually crossed over around 3-4kHz, so upgrading the mains gives you more bang for your buck.

Can I install component speakers in the Hyundai XG350 front doors?

Yes, the front door panels accept both coaxial and component configurations. Component systems separate the tweeter from the woofer - you'd mount the 6.5 inch woofer in the existing location and relocate the tweeter. Problem is finding a good tweeter mounting spot since there's already a 0.75 inch tweeter location. You might end up with dual tweeters or need to modify the panel. Coaxials are simpler but components typically offer better imaging... if you can position them properly.

What power handling should I look for in replacement speakers for my XG350?

Most aftermarket 6.5 inch speakers handle 50-100 watts RMS, which works well with factory head units or modest amplifiers. The Hyundai XG350's stock system probably outputs around 15-25 watts per channel. Don't get too caught up in peak power ratings - they're mostly marketing. RMS matters more. For the 6x9s in the rear deck, look for 75-150 watts RMS since they have more cone area to dissipate heat. Higher power handling gives you headroom, not necessarily louder volume.

Why does my Hyundai XG350 have both tweeters and coaxial speakers in the front doors?

The separate 0.75 inch tweeter handles the highest frequencies while the 6.5 inch coaxial likely has its built-in tweeter disabled or filtered out. This creates a pseudo-component setup without the complexity. The dedicated tweeter probably crosses over around 5kHz or higher, leaving the coax to handle mids and upper bass. It's actually a decent factory approach... when it works. Sometimes the imaging gets weird with tweeters at different heights though.

Should I upgrade to triaxial speakers in my XG350's rear deck?

Triaxials add a midrange driver to the typical woofer-tweeter combo, which sounds good in theory. The 6x9 size gives you room for all three elements. But rear speakers are mainly for ambiance and fill in your Hyundai XG350 - the front stage does the heavy lifting. A quality coaxial or even full-range 6x9 might serve you better than a mediocre triaxial. Depends on your budget and whether you're running an amplifier back there. More drivers isn't always better drivers.
