Infiniti G20 Speaker FAQ

Should I replace the front door speakers or rear deck speakers first in my Infiniti G20?

Replace the front door 6.5 inch speakers first. Your ears naturally focus on sound coming from in front of you, so the front door panel speakers handle most of the vocal clarity and midrange detail. The rear deck 6 x 9 speakers mostly fill in bass and ambient sound. Front speakers typically get 80% of your attention while driving. Start with quality 6.5 inch coaxials rated around 50-75 watts RMS if you're keeping the factory amplifier.

What's the difference between coaxial and component speakers for the Infiniti G20 front doors?

Coaxial speakers combine the tweeter and woofer in one unit - simpler installation, single mounting point. Component speakers separate the tweeter from the woofer, which might explain why some G20 models have dedicated 1 inch tweeters in the A-pillar. Components usually sound better because you can position the tweeter optimally for imaging. But coaxials work fine if you want easy replacement. The front door panels can handle either type, though components require more wiring work.

Can I use the existing A-pillar tweeter location when upgrading my Infiniti G20 speakers?

The A-pillar tweeter location works well if you're installing component speakers in the front doors. That 1 inch tweeter spot gives good stereo imaging since it's closer to ear level. You'll need to verify the crossover frequencies match - most aftermarket components cross over around 3000-4000 Hz. The factory tweeter might be 4 ohm or 8 ohm, so check impedance compatibility. Some people just replace the door speakers with good coaxials and leave the A-pillar alone.

What power handling should I look for in Infiniti G20 replacement speakers?

The factory system probably pushes around 15-25 watts RMS per channel. Look for speakers that can handle 50-100 watts RMS - this gives you headroom for a future amplifier upgrade. The 6 x 9 rear speakers can typically handle more power than the 6.5 inch fronts due to their larger cone area. Don't get caught up in peak power ratings, those numbers are mostly marketing. RMS power handling tells you what the speaker can actually use continuously.

Why do some Infiniti G20 models have triaxial rear speakers?

Triaxial means three-way speaker with separate woofer, midrange, and tweeter elements. The rear deck 6 x 9 location has enough space for this configuration, and it helps fill in the full frequency range from the back of the car. Not all G20 models came with triaxials though - some just had full-range or coaxial rear speakers. The extra drivers in triaxials can improve frequency response, but the quality depends on the specific speaker design. Sometimes a good coaxial performs better than a cheap triaxial.
