Infiniti QX50 Speaker FAQ

Which speakers should I replace first in my Infiniti QX50?

Replace the front door panel speakers first. Your Infiniti QX50 has 6.5-inch coaxial or component options in both front doors, but the front speakers handle most vocal frequencies and stereo imaging. The rear door panels can use coaxial, component, or full-range types - though you'll probably notice the biggest improvement by upgrading fronts with quality component speakers around 75-100 watts RMS. The factory speakers might be running at 4-ohm impedance, so check your head unit specs before installing aftermarket components.

Can I mix coaxial and component speakers in my Infiniti QX50?

You could install components up front and coaxials in the rear doors. Component speakers in the front 6.5-inch locations give you separate tweeters and woofers - better frequency separation. The rear positions work fine with coaxial speakers since they're mainly for fill and ambient sound. Full-range speakers are another option for the rear but they tend to sound... compressed compared to coaxials. Make sure your amplifier can handle the combined load if you're mixing different impedances.

What's the difference between the speaker types available for my Infiniti QX50?

Component speakers split frequencies between separate drivers - tweeters handle highs (3kHz and up), woofers take mids and lows. Better stereo imaging but requires more installation work. Coaxial speakers combine everything in one unit, easier install, decent sound quality. Full-range speakers try to reproduce all frequencies through a single driver - they're only available for rear positions in your QX50. Components typically cost more but the crossover networks usually provide cleaner frequency response around 2.5-4kHz where vocals sit.

How do I verify speaker compatibility with my Infiniti QX50's electrical system?

Check your head unit's power output first - probably 15-25 watts RMS per channel from factory. Your 6.5-inch speakers should match at 4-ohm impedance, though some aftermarket options run at 8-ohms. Measure the mounting depth in both front and rear door panels before ordering. Component speakers need extra space for crossovers, and some tweeters might require custom mounting in the Infiniti QX50's door panels. Test one speaker before installing all four to make sure impedance matching works with your system.
