Acura ZDX Speaker FAQ

Which Acura ZDX speakers should I upgrade first for the biggest sound improvement?

Start with the front door panel 6.5-inch speakers. These handle most of your music's midrange and some bass - around 80-5000 Hz typically. The Acura ZDX front doors can accommodate both coaxial and component speakers, so you have flexibility. Component speakers might give you better imaging since the A-pillar tweeters are already positioned well. Budget around 50-100 watts RMS per speaker. The rear doors come second priority, but honestly? The front stage does most of the work.

Can I replace the 8-inch cargo area speaker in my Acura ZDX with an aftermarket subwoofer?

You probably can, but check the mounting depth first. The original 8-inch unit might be a full-range driver trying to do bass duty. A proper 8-inch sub would need 150-300 watts and work better in a small enclosure. The cargo location isn't ideal for bass response though - you might get uneven frequency response. Consider the impedance too. Most factory systems run 4-ohm speakers, but verify with a multimeter before connecting anything new.

Why does my Acura ZDX have both dashboard and A-pillar tweeters?

The 3-inch dashboard speakers handle upper midrange and some treble - maybe 1000-8000 Hz. The 1.5-inch A-pillar tweeters focus on higher frequencies, 3000 Hz and up. It's about staging and dispersion patterns. Dashboard speakers fire more directly at you, while A-pillar units create wider soundstage. When upgrading, match the impedance of the originals. The dashboard location might accept small full-range drivers if you want more midrange punch, but... the A-pillar tweeters are probably doing the real high-frequency work.

Should I upgrade the 3-inch C-pillar speakers in my Acura ZDX?

These are probably your last priority. C-pillar speakers mainly fill in rear ambiance - they're not critical for sound quality. Most 3-inch coaxials max out around 30-40 watts anyway. If your front stage sounds good, the C-pillars just add some spaciousness. Save your money for the front doors and maybe the 8-inch cargo speaker. Though if you're running a full system upgrade... small coaxials there can help with surround effects. Just don't expect much bass from that location.

What's the difference between coaxial and component options for Acura ZDX door speakers?

Coaxials put the tweeter right on the woofer - simpler installation, one crossover point around 3000-4000 Hz. Components separate the tweeter and woofer, letting you use those A-pillar locations for better imaging. With components in the Acura ZDX, you'd run woofers in the doors and connect tweeters to the A-pillar spots. The crossover network gets more complex - usually 6-12 dB slopes. Components typically cost more but give you better soundstage width. Your existing A-pillar tweeters suggest the car was designed for component separation anyway.
