Nissan NX Speaker FAQ

What speakers should I replace first in my Nissan NX?

Replace the front door panel speakers first. The 4 x 6 inch front speakers handle most of your music's mid-range frequencies and vocals. These get the most use and typically show wear faster than rear speakers. The front position also gives you better stereo imaging - you'll notice sound quality improvements immediately. Start with 40-60 watt RMS coaxial speakers for the front doors, then consider the 6.5 inch rear speakers later.

Can I install component speakers in my Nissan NX front doors?

Yes, but mounting the tweeter might require custom work. The front door panels accept 4 x 6 inch speakers in coaxial, component, or plate speaker formats. Component systems separate the tweeter from the woofer - this usually means better sound staging. However, you'll need to find mounting spots for the tweeters, possibly in the A-pillars or dashboard. The crossovers can mount behind the door panel. Most people stick with quality coaxial speakers for simpler installation.

What's the difference between the front and rear speaker sizes in a Nissan NX?

Front doors use 4 x 6 inch speakers while rear panels accommodate 6.5 inch round speakers. The larger rear speakers can produce deeper bass frequencies - typically down to around 50-60 Hz compared to 80-90 Hz for the smaller fronts. But the 4 x 6 format gives you more surface area than a 5.25 inch round speaker. The rear 6.5 inch speakers work well as midrange drivers or full-range coaxials, depending on your setup goals.

Do I need special adapters for Nissan NX speaker installation?

Probably not for the standard sizes. The 4 x 6 inch front speakers should mount directly to the factory brackets. Same with the 6.5 inch rear speakers - they're a common automotive size. You might need spacer rings if your new speakers are slightly thicker than stock. Check the mounting depth before buying. Some aftermarket speakers need 2-3 inches of clearance behind the mounting surface. The Nissan NX door panels have limited space, so measure first.

What impedance should I look for in Nissan NX replacement speakers?

Stick with 4-ohm speakers. Most factory car audio systems, including the Nissan NX, are designed for 4-ohm loads. Using 8-ohm speakers will reduce power output from your head unit - you'll get maybe half the volume. Some high-end component systems come in 8-ohm configurations, but they're meant for external amplifiers. For direct head unit connection, 4-ohm speakers give you the best power transfer and volume levels.
