Acura NSX Speaker FAQ

What speakers should I upgrade first in my Acura NSX for the biggest sound improvement?

Replace the front door speakers first - they handle most vocal reproduction and midrange frequencies. The 5.25 inch front door speakers in newer NSX models typically see 50-80 watts RMS, while the 6.75 inch versions in earlier models can handle slightly more power. Component speakers will give you better staging than coaxials here. The dashboard 4 inch speakers matter less for overall impact, though they do fill in some upper frequencies.

Can I install component speakers in all Acura NSX speaker locations?

Most locations support component speakers, but the dashboard 4 inch position might be tricky for tweeter placement. The front door panels work well with components - you get better separation between woofer and tweeter frequencies. Rear deck installations can use components too, though the mounting depth varies. Check your amplifier's crossover settings... some factory systems run these at 4 ohms, others at 8 ohms. Component systems usually want clean 75+ watts per channel.

Why does my Acura NSX have different speaker sizes between model years?

The door panel redesign changed the speaker mounting diameter. Earlier NSX models used 6.75 inch speakers in the front doors, then switched to 5.25 inch around 1995. This affects your replacement options - the larger speakers generally move more air and handle lower frequencies better. You're looking at maybe 45-65 Hz response on the 6.75 inch versus 55-75 Hz on the smaller ones. The rear deck stayed consistent at 6.5 inch once they added it.

Should I use coaxial or component speakers in my Acura NSX rear deck?

Component speakers work better if you can mount the tweeters properly, but coaxials are simpler for rear fill duties. The rear deck position doesn't need perfect imaging since you're mainly adding ambiance and depth. Quality coaxials around 60-80 watts RMS should be sufficient. Make sure the mounting depth fits - some aftermarket speakers are deeper than the factory units. The impedance should match your amplifier, typically 4 ohms for most NSX audio systems.

What power handling should I look for in Acura NSX replacement speakers?

Front speakers need 75-100 watts RMS for good headroom, especially if you're upgrading the amplifier later. The smaller 5.25 inch speakers might seem limited but good ones can surprise you with output. Rear speakers can work with 50-75 watts RMS since they're supporting rather than leading. Check your current amplifier output first though - factory systems usually provide 15-25 watts per channel. Adding an aftermarket amplifier changes everything... then you want speakers that can handle the extra power without distortion.
