Infiniti G37 Speaker FAQ

Which speakers should I replace first in my Infiniti G37 for the biggest sound improvement?

Replace the 6.5 inch front door speakers first. These handle most of your music's midrange frequencies and vocals. The front doors in the Infiniti G37 typically accommodate 50-75 watts RMS, 4-ohm speakers with frequency response around 40Hz-20kHz. You'll hear immediate improvement in clarity and bass response. The 6.5 inch size gives you plenty of aftermarket options... component systems work particularly well here if you're keeping the factory tweeters.

Can I install component speakers in the Infiniti G37 front doors without major modifications?

Yes, but it depends on your specific setup. The front doors accept both coaxial and component speakers in 6.5 inch size. If you have the 1 inch tweeters already mounted, you might be able to use those locations for component tweeters. Otherwise, surface-mounting new tweeters on the door panels usually works. The crossovers can typically fit behind the door panel... though some people mount them under seats for easier access. Power handling should be around 60-80 watts RMS for optimal performance.

What's the deal with multiple speaker sizes listed for the same location in my Infiniti G37?

Different trim levels and configurations used different speaker arrangements. Some G37 models have 6.5 inch main drivers with separate 3.5 inch midrange speakers and 1 inch tweeters in the front doors. Others use simpler 6.75 inch coaxial speakers. Check your actual doors to see what you have. The 3.5 inch speakers handle midrange frequencies around 200Hz-5kHz typically. If you're upgrading, focus on the largest speakers first since they'll make the most difference.

Should I bother upgrading the rear deck speakers in my Infiniti G37?

The 6 x 9 inch rear deck speakers can add decent bass fill, especially if you're not adding a subwoofer. They're usually rated for 30-50 watts RMS and handle frequencies down to about 35Hz. But honestly, most of your sound staging comes from the front. The 5.25 inch rear deck option in some models provides less bass but cleaner midrange. Replace these after you've done the fronts and only if you notice the rear soundstage feels empty during your daily driving.

How much power do the factory Infiniti G37 speakers handle?

Factory speakers typically handle 15-25 watts RMS, maybe 40-60 watts peak. Pretty conservative ratings. The 6.5 inch and 6 x 9 inch speakers can probably take more abuse than the smaller ones. When upgrading, look for aftermarket speakers rated 50-75 watts RMS for the larger sizes, 25-40 watts for the 3.5 inch and 4 inch speakers. Most decent head units in the G37 push around 18-22 watts RMS per channel, so you'll have headroom for dynamics without an external amplifier.
