Infiniti EX37 Speaker FAQ
What speakers should I upgrade first in my Infiniti EX37?
Start with the front door panel 6.5 inch speakers. These handle most of your music's critical midrange and vocal frequencies. The front doors get the most power from your head unit and sit closest to your ears. Component speakers work best here - separate the woofer from tweeter for cleaner sound staging. You'll notice the biggest improvement replacing these first, especially if you listen to vocals or acoustic music.
Can I install component speakers in all Infiniti EX37 locations?
The front doors and rear doors accept components, but dashboard tweeters are separate 1 inch units. Front door components typically handle 80-120 watts RMS around 4 ohms. Rear doors might work better with coaxials since they're mainly for fill. The cargo area 5.25 inch speakers... depends on your listening setup. Components need crossovers and more wiring. Stick with coaxials in rear positions unless you're doing a full system rebuild.
Why does my Infiniti EX37 have different speaker sizes in different locations?
The 6.5 inch door speakers handle midrange punch and bass response down to maybe 50-60Hz. Dashboard 1 inch tweeters cover highs from 3kHz up. The 5.25 inch cargo speakers fill in rear soundstage - smaller size fits the space constraints back there. This size variation creates frequency overlap. Door speakers can't reach extreme highs effectively, tweeters can't do low frequencies. It's about matching driver size to frequency range and available mounting space.
Should I replace the dashboard tweeters in my Infiniti EX37?
Maybe later in your upgrade path. Those 1 inch tweeters extend your frequency response above 4kHz, but they're limited by power handling - probably 15-25 watts max. If your new door speakers have good high-frequency response up to 15kHz or so, the dashboard units become less critical. Some people disconnect them entirely when running quality components up front. Test your system first with just door upgrades. The tweeters might actually create harsh spots or imaging problems depending on your new speakers' characteristics.
What's the difference between coaxial and component options for the Infiniti EX37?
Coaxials mount everything in one frame - woofer with tweeter attached. Simple installation, single wire connection. Components separate the tweeter from woofer completely. Better sound staging since you can position tweeters optimally, usually higher up. Crossovers filter frequencies to each driver. Front doors benefit most from components because imaging matters there. Rear positions? Coaxials make more sense unless you're building a serious audiophile setup. Component installation takes longer and costs more.
