Subaru Justy Speaker FAQ

What speakers should I replace first in my Subaru Justy for better sound quality?

Replace the dashboard 4 x 6 inch speakers first. These handle most of your mid-range frequencies and vocals, so upgrading them creates the biggest immediate improvement. The dashboard location also means easier access compared to door panel work. Look for full-range speakers rated around 40-60 watts RMS with 4-ohm impedance. The rear door 5.25 inch positions can wait - they're mainly for fill and ambiance in the Justy's compact cabin.

Can I install component speakers in the Subaru Justy rear doors?

Yes, the rear door panels accept both coaxial and component 5.25 inch speakers. Component systems might give you better staging since you can position tweeters separately. However, the Justy's rear door space is pretty tight for mounting crossovers. Most people go coaxial for simplicity. If you choose components, plan on custom tweeter mounting - the factory locations weren't designed for separate tweeters. Coaxials around 50 watts RMS work well without amplification.

Why are the dashboard speakers 4 x 6 inch instead of round in the Subaru Justy?

The 4 x 6 inch oval shape fits the dashboard contours better in the Justy's compact design. Oval speakers also provide more cone area than a round 4 inch would - roughly equivalent to a 5 inch round speaker. This gives you better low-mid response in the critical 80-500 Hz range where vocals and instruments live. The dashboard placement aims sound directly at passengers rather than bouncing off surfaces. Just make sure replacement speakers have similar mounting depth - usually around 2 inches maximum.

Do I need an amplifier for aftermarket speakers in my Subaru Justy?

The factory head unit probably puts out around 15-20 watts per channel. That's enough for basic coaxial speakers but you'll want more power for better dynamics. An amplifier helps, especially for the 5.25 inch rear doors which can handle 60+ watts without strain. The dashboard 4 x 6 speakers tend to be more efficient so they work okay with head unit power. Start with just speaker upgrades - if it's not loud enough or sounds strained at higher volumes, then add amplification.

What's the difference between coaxial and full-range speakers for the Subaru Justy dashboard?

They're basically the same thing - both terms describe speakers with tweeter and woofer in one unit. Full-range just emphasizes that it covers the complete frequency spectrum, roughly 60 Hz to 20 kHz. The Justy's dashboard 4 x 6 location works well for this since you want full frequency coverage from your primary speakers. Component systems would separate the tweeter but dashboard space makes that tricky. Stick with quality coaxial/full-range speakers with silk or textile tweeters for smoother sound in the small cabin.
