Infiniti I30 Speaker FAQ
Which speakers should I replace first in my Infiniti I30 for the biggest sound improvement?
Start with the front door panel 6.5 inch speakers. These handle most of your music's midrange and vocal frequencies, so upgrading them creates the most noticeable difference. Look for coaxial speakers rated around 50-75 watts RMS with 4-ohm impedance. The front speakers in your Infiniti I30 do most of the heavy lifting for stereo imaging. After that, consider the rear door 6.5 inch speakers if you frequently have passengers. The tweeters can wait - they're supporting players, not the main show.
Can I install component speakers in my Infiniti I30's front doors instead of coaxials?
Yes, the front door panels accept both coaxial and component speakers. Component systems separate the tweeter from the woofer, typically improving soundstage and clarity. You'll mount the 6.5 inch woofer in the door and the tweeter... well, that depends on your year. 1996-1999 Infiniti I30 models have dedicated 1 inch tweeter locations in the front doors. 2000-2001 models moved tweeters to the A-pillar. Component speakers usually require more power - around 75-100 watts RMS - but the separation creates better frequency response. Just verify your crossover fits somewhere accessible.
What's the difference between the rear deck speakers in 2000-2001 Infiniti I30 models?
The rear deck lid houses 8 inch speakers that can be either full-range or subwoofer types. Full-range 8 inch speakers handle frequencies from roughly 50Hz to 15kHz, giving you decent bass extension without needing an amplifier. Subwoofer types focus on low frequencies - typically 20Hz to 200Hz - but require an external amp to function properly. The 8 inch size in your Infiniti I30 provides more bass response than the 6.5 inch door speakers. If you're not adding a separate subwoofer system, full-range speakers make more sense. They're usually rated around 40-60 watts RMS at 4 ohms.
Why do some Infiniti I30 models have different tweeter locations?
Infiniti redesigned the dashboard layout between 1999 and 2000. Earlier I30 models (1996-1999) integrated 1 inch tweeters into the front door panels alongside the main speakers. Later models (2000-2001) moved tweeters to the A-pillar for better stereo imaging. A-pillar placement aims the high frequencies more directly at your ears. The door-mounted tweeters in earlier Infiniti I30 models... they work fine but the angle isn't as precise. This affects how component speaker systems integrate. Some installers prefer the A-pillar location for aftermarket components because it creates better soundstage width.
