Mazda Protege5 Speaker FAQ

What speakers should I replace first in my Mazda Protege5 for the biggest sound improvement?

Replace the front door panel speakers first. They handle most of your music's midrange and vocal frequencies. The 6x8 inch front speakers get more power from your head unit - typically around 15-20 watts RMS. Rear doors can wait. Your ears naturally focus forward while driving, so front speaker upgrades deliver more noticeable results than rear replacements.

Can I install component speakers in my Mazda Protege5 door panels?

Yes, both front and rear door panels accept component speakers. You'll need to mount the tweeter separately though. Front doors work well with 6x8 inch component sets around 50-75 watts RMS. The crossover networks might need custom mounting behind the door panel. Component speakers separate frequencies better than coaxials - tweeters handle 3kHz and up while woofers cover bass and midrange. This creates clearer sound staging in your Protege5.

What's the difference between coaxial and full-range speakers for my Mazda Protege5?

Coaxial speakers have a separate tweeter mounted on the woofer cone. Full-range speakers use one cone for all frequencies. Both fit your Protege5's door panels, but coaxials typically sound clearer above 2kHz. The 6.5 inch rear doors work fine with either type. Front 6x8 coaxials often perform better because... well, the larger cone area helps with midrange clarity. Full-range speakers cost less but sacrifice some high-frequency detail.

Do I need an amplifier for aftermarket speakers in my Mazda Protege5?

Not necessarily, but it helps. Your factory head unit probably outputs 12-18 watts RMS per channel at 4 ohms. Most aftermarket speakers handle 25-60 watts RMS, so they'll work fine without an amp. However, adding a 4-channel amplifier around 40-50 watts RMS per channel will... the difference becomes obvious immediately. Your Protege5's door speakers will sound fuller and handle dynamic peaks without distortion.

What impedance should I choose for Mazda Protege5 replacement speakers?

Stick with 4-ohm speakers. Your Protege5's factory system expects 4-ohm loads. Using 8-ohm speakers reduces power output by roughly half - your 15-watt head unit becomes more like 7-8 watts. Some people try 2-ohm speakers thinking they'll get more volume, but most factory head units can't handle the increased current draw. The result? Overheating and potential damage to your audio system.
