Nissan Pulsar NX Speaker FAQ

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

Start with the front door panel 6.5 inch speakers. These handle most of your music's mid-range frequencies and vocals - they're what you hear most directly. The front doors typically get 60-70% of your stereo's power distribution anyway. Rear deck and side panel speakers can wait since they mainly fill in ambient sound. Front door upgrades give you the most noticeable difference for your money.

Can I install component speakers in all locations of my Nissan Pulsar NX?

Yes, all three locations support component speakers, but the front doors make the most sense. Component systems separate tweeters from woofers - you'd mount tweeters in the door panels and woofers lower down. The 6 x 9 inch rear side panels might be tricky for component mounting since you need separate tweeter locations. Coaxial speakers are probably more practical for rear positions unless you're doing a full custom install.

What power handling should I look for in Nissan Pulsar NX replacement speakers?

Aim for 50-75 watts RMS for the front 6.5 inch speakers, 40-60 watts for the rear 5.25 inch deck speakers. The 6 x 9 inch side panels can handle more - maybe 80-100 watts RMS since they have larger surface area. Your factory head unit probably puts out 15-20 watts per channel, so don't worry about matching exact power ratings. Higher power handling just means they won't distort when you turn things up.

Do 6 x 9 inch speakers in the rear side panels improve bass response significantly?

They help, but don't expect subwoofer-level bass. The 6 x 9 configuration moves more air than smaller speakers, so you'll get some low-end improvement around 80-120 Hz. But the Nissan Pulsar NX's rear side panel mounting probably isn't ideal for deep bass since the panels flex. If you want real bass improvement, consider a small subwoofer instead. The 6 x 9s are better for filling out mid-bass and overall volume.

What impedance should I choose for Nissan Pulsar NX speaker replacements?

Stick with 4-ohm speakers across all locations. Most aftermarket car speakers are 4-ohm anyway, and your factory stereo is designed for this impedance. Using 8-ohm speakers will reduce your available power by roughly half. Some people think 2-ohm speakers give more volume, but they can overheat your amplifier circuits. The impedance matters more than exact wattage ratings for compatibility.
