Nissan 370Z Speaker FAQ

Which speakers should I replace first in my Nissan 370Z for the best sound improvement?

Start with the 6x9 inch front door speakers. They handle most of your music's foundation - everything from about 80Hz up through the midrange frequencies. The 370Z routes significant power through these positions, typically 25-30 watts RMS. After that? The 2.5 inch dashboard speakers matter more than you'd think. They fill in presence frequencies around 2-4kHz that make vocals pop. The rear 3.5 inch units can wait unless you frequently carry passengers.

What's the difference between the 6x9 and 6.5 inch speakers in my 370Z's doors?

The 6x9 inch speakers act as your primary full-range drivers, reproducing frequencies from roughly 60Hz to 15kHz. The 6.5 inch woofers focus on midbass punch - that 80-250Hz range where kick drums and bass guitars live. Some Nissan 370Z configurations only use one or the other, depending on the audio package. If you have both, the system probably crosses them over around 200Hz. Component sets work best here since they're designed to work together across frequency ranges.

Why does my 370Z have 5.25 inch speakers in the cargo area instead of bigger ones?

Space constraints mainly. The cargo area panels can't accommodate larger drivers without major modifications. These 5.25 inch woofers still produce decent midbass down to about 70Hz when properly powered. They're positioned to use the trunk as an acoustic chamber - sort of like a makeshift enclosure. Adding 50-60 watts RMS to these locations transforms the rear soundstage. Just... don't expect subwoofer-level bass. That requires actual subs.
