Nissan March Speaker FAQ

What speakers should I replace first in my Nissan March?

Start with the front door panel speakers. The 6.5 inch midbass units in the front doors handle the most critical frequency range for perceived sound quality, roughly 80 Hz to 5,000 Hz, and they are the ones your ears focus on most during listening. The rear door panel speakers in the Nissan March are supporting players at best. Replacing the front pair first tends to give you the most noticeable improvement per dollar spent. You can always add the rear speakers later.

What type of replacement speaker works best in the Nissan March front door positions?

A component speaker set is likely your best option for the front door panel positions. These separate the woofer from the tweeter, allowing each driver to focus on its own frequency range. The Nissan March already has dedicated 1 inch tweeter locations in the A-pillar, which means the vehicle is essentially designed for this kind of setup. Component sets typically include a crossover that filters frequencies, sending highs above roughly 3,500 Hz to the tweeter and everything below to the 6.5 inch woofer. The result is generally cleaner separation and better imaging compared to a coaxial driver trying to do everything at once.

Can I put a coaxial speaker in the Nissan March door panels instead of a component set?

Yes, coaxial speakers will fit the 6.5 inch door openings in the Nissan March. A coaxial speaker combines the woofer and tweeter into one unit, which simplifies installation considerably. The tradeoff is that the built-in tweeter sits in the door, not at ear level, so stereo imaging tends to suffer. It can work fine and the sound will still be better than stock. Whether that matters depends on how much you care about soundstage.

What is the A-pillar tweeter for in the Nissan March and should I upgrade it?

The 1 inch tweeter mounted in the A-pillar of the Nissan March handles high-frequency content, typically from around 3,500 Hz up to 20,000 Hz or beyond. The factory unit is almost certainly a basic piezo or low-cost mylar dome. Upgrading to a silk dome tweeter in that same location tends to smooth out harsh high frequencies. Silk domes generally roll off more gently above their upper limit, which reduces listening fatigue on longer drives. The A-pillar position is actually quite good for imaging since it points the tweeter closer to ear level, so a better driver there can make a meaningful difference.

What power handling should I look for when replacing the Nissan March door speakers?

The factory head unit in the Nissan March likely produces somewhere around 14 to 20 watts RMS per channel. Replacement speakers rated at 40 to 80 watts RMS should be more than adequate for this setup. There is a common tendency to focus on peak power ratings, which can be misleading. RMS is the number that actually matters for matching speakers to amplifier output. If you plan to add an external amplifier later, looking for speakers rated at 75 watts RMS or higher gives you room to grow without replacing the speakers again.
