Infiniti FX50 Speaker FAQ
Which speakers should I prioritize upgrading first in my Infiniti FX50?
Start with the front door panel 6.5 inch speakers. These handle most of your music's midrange and vocal frequencies. The front doors typically receive the strongest signal from your head unit too. Component speakers work best here - you get separate woofers and tweeters for clearer sound staging. The existing 1 inch dashboard tweeters might actually complement new front components well, though you'll want to verify crossover compatibility first.
Can I install component speakers in all locations of my Infiniti FX50?
The front and rear door panels plus cargo area can handle component systems. Your Infiniti FX50 shows coaxial and component compatibility in these spots. However, the center dash location appears limited to coaxial or full-range types only. Component systems need separate mounting for tweeters and woofers - the 3.5 inch center dash space probably won't accommodate this setup. Stick with a quality full-range driver there, maybe something rated around 30-50 watts RMS.
What's the difference between the speaker types listed for my Infiniti FX50?
Coaxial speakers combine the woofer and tweeter in one unit. Simpler installation, decent sound. Component speakers separate these elements - woofer handles bass/midrange, dedicated tweeter covers highs. Usually sounds more precise but requires more wiring. Full-range drivers attempt to cover the entire frequency spectrum in one speaker. The rear door panels show all three options, which means you have flexibility depending on your budget and sound goals.
Should I replace the 1 inch dashboard tweeters in my Infiniti FX50?
Maybe hold off initially. Those dashboard tweeters might integrate well with upgraded front door components. If you install a component system in the front doors, you'll get new tweeters anyway. Test the sound first - the factory dashboard units could actually fill in some frequency gaps. However, if they sound harsh or disconnected after your door upgrades, then consider replacement. Look for tweeters that match your new components' impedance, typically 4 ohms.
What power handling should I look for in Infiniti FX50 replacement speakers?
The 6.5 inch door speakers can probably handle 75-100 watts RMS comfortably. Don't go crazy with power - your factory amplifier likely outputs 20-40 watts per channel anyway. The 5.25 inch cargo speakers should handle 50-75 watts RMS. That 3.5 inch center dash speaker won't need much - 25-40 watts RMS maximum. Remember, RMS ratings matter more than peak power numbers. Higher sensitivity ratings around 88-92 dB will sound louder with your existing amplifier.
