Mazda RX-7 Speaker FAQ

What speakers should I replace first in my Mazda RX-7?

Replace the front door panel speakers first - they handle most of your midrange and vocal frequencies. The 6.5 inch front door speakers get priority because they're positioned closest to your ears. Dashboard speakers come second since they affect stereo imaging. Rear speakers can wait unless you frequently carry passengers. Front kick panel 4 inch speakers might seem small but they actually contribute significantly to soundstage width in older RX-7 models.

Should I choose coaxial or component speakers for my Mazda RX-7?

Component speakers offer better sound separation but require more installation work. Coaxials work well if you're keeping the factory head unit - they're simpler to install and don't need crossovers. The dashboard location in the RX-7 actually works better with coaxials since mounting separate tweeters there can be challenging. Component systems shine in the front door panels where you have space for proper tweeter placement. Consider your amplifier situation too - components typically need more power to sound their best.

Can I use 6x8 speakers in place of 6.5 inch speakers in my Mazda RX-7?

Not directly - the mounting holes won't align properly. 6x8 speakers have a different bolt pattern than 6.5 inch round speakers. You'd need adapter brackets or custom mounting. The 6x8 oval shape does provide more cone area though, potentially improving bass response. Some people modify the door panels, but that's permanent. Stick with the original 6.5 inch size unless you're planning extensive modifications to your RX-7's door panels.

What power handling should I look for in Mazda RX-7 replacement speakers?

Look for speakers that can handle 50-75 watts RMS for the front doors, less for smaller locations. Most factory head units put out around 15-20 watts per channel, so you don't need massive power handling initially. The 4 inch kick panel speakers work fine with 30-40 watts RMS. If you're planning to add an amplifier later, consider speakers with higher power handling - maybe 100+ watts RMS for the main speakers. Remember that RMS ratings matter more than peak power numbers.

Why do some Mazda RX-7 models have speakers in different locations?

Different model years had varying interior designs and audio system configurations. The rear deck lid speakers work well for rear fill but can sound boomy if positioned wrong. Dashboard speakers help with stereo imaging but limited space affects bass response. Door panel speakers became more common in later models as door construction improved. The kick panel location actually provides good soundstage width despite the small 4 inch size. Each location has acoustic trade-offs based on the RX-7's interior shape and driver position.
