Infiniti QX80 Speaker FAQ

What speakers should I replace first in my Infiniti QX80 for better sound quality?

Replace the front door panel speakers first. The 6.5-inch front speakers handle most of your music's midrange and vocal frequencies. Component speakers work best here - they separate the tweeter from the woofer, giving you better imaging and clarity. You'll notice the biggest improvement in dialogue and instrument separation. The rear door speakers can wait since they mainly provide fill sound. Though if you're on a budget, decent coaxial speakers in front still beat factory units.

Can I install component speakers in both front and rear doors of my QX80?

Yes, both locations accept component speakers. The front doors are probably your best bet for components since that's where you'll hear the most detail. Component systems typically run 50-80 watts RMS and need separate mounting for tweeters. Your Infiniti QX80's rear doors can handle components too, but you might not notice as much difference back there. The 4-ohm impedance should work with most aftermarket components. Just verify your amp can drive the additional tweeter load if you're going full component front and rear.

What's the difference between coaxial and component speakers for my Infiniti QX80's 6.5-inch openings?

Coaxial speakers have the tweeter mounted directly on the woofer - easier install, one mounting point. Component speakers separate everything: woofer goes in the door, tweeter mounts elsewhere, crossover handles frequency splitting. Components usually sound better because the tweeter can be positioned at ear level. In your QX80, components might give you 15-20% better clarity, especially in the 2kHz-8kHz range where vocals live. Coaxials are simpler though. Less wiring, no crossover mounting. If you're not an audiophile, quality coaxials can sound quite good.

Will full-range speakers work well in my QX80's rear doors?

Full-range speakers handle everything from bass to treble in one driver. They work fine for rear fill in the Infiniti QX80, especially if you're not trying to create a concert hall back there. Most full-range 6.5-inch speakers cover roughly 80Hz to 18kHz. The trade-off is they can't excel at any particular frequency range like dedicated components do. Your rear passengers might actually prefer them since full-range speakers often have more forgiving sound characteristics. Just don't expect the same detail you'd get from a proper component setup.
