Nissan Stanza Speaker FAQ

Which speakers should I replace first in my Nissan Stanza for the biggest sound improvement?

Replace the front door speakers first. They handle most vocals and midrange frequencies you actually hear while driving. The rear deck speakers mostly add bass fill and ambient sound. Front 6.5 inch coaxials around 50-75 watts RMS will give you the most noticeable upgrade. Component speakers work even better if you want crisp highs, but coaxials are simpler to install and still sound good.

Can I put 6.5 inch speakers in the 4 x 6 inch front door locations on my Nissan Stanza?

Probably not without modification. The 4 x 6 inch opening is specifically shaped for that size. You'd need to cut or modify the door panel mounting area. Stick with quality 4 x 6 inch coaxials rated around 40-60 watts RMS instead. Polk, Pioneer, or JBL make decent options that'll fit properly. The improvement comes more from speaker quality than size anyway.

What's the difference between coaxial and component speakers for my Nissan Stanza?

Coaxial speakers have the tweeter built into the woofer - everything in one unit. Components separate the tweeter from the woofer, usually sound clearer because each driver handles specific frequencies better. Components need crossovers though, more complex wiring. For the Nissan Stanza's factory locations, coaxials often make more sense unless you're doing a serious audio build. The improvement might not justify the extra installation work.

Why do some Nissan Stanza models have 6 x 9 inch rear speakers while others have smaller sizes?

Different trim levels and design changes. The 6 x 9 inch speakers typically move more air, better bass response. But they're not automatically better - depends on the actual speaker quality and power handling. A good 6.5 inch speaker with proper 4-ohm impedance matching often sounds better than a cheap 6 x 9 inch. Check your specific Nissan Stanza's rear deck space before ordering anything.

What impedance should I look for when replacing Nissan Stanza speakers?

Stick with 4-ohm speakers. Most factory car audio systems expect 4-ohm loads. Using 8-ohm speakers might work but you'll get less volume from your head unit. 2-ohm speakers could potentially damage your factory amplifier if it's not designed for lower impedance. 4-ohm gives you the best balance - proper power transfer without stressing the electronics in your Nissan Stanza.

Do I need an amplifier when upgrading Nissan Stanza speakers?

Not necessarily for basic upgrades. Factory head units usually push 15-20 watts RMS per channel, enough for decent aftermarket speakers. But if you want serious volume or bass, an amplifier helps. Start with good speakers first, see how they sound. You can always add a 4-channel amp later - around 50-75 watts RMS per channel works well for most Nissan Stanza setups. Wire gauge matters more than you'd think for amp installations.
