Plymouth Horizon Speaker FAQ

What speakers should I replace first in my Plymouth Horizon?

Start with the front 5.25 inch door speakers. They handle most vocals and midrange frequencies between 250-4000 Hz, which is where you'll notice the biggest improvement in clarity. The rear 6x9s can wait - they're mainly for fill and bass support. Front speakers typically see more wear anyway since they're doing the heavy lifting for stereo imaging.

Can I install component speakers in my Plymouth Horizon front doors?

Yes, the front 5.25 inch locations accept component systems. You'll need to mount the tweeter somewhere in the door panel or dash - most people use the existing mounting points near the door handle. Component speakers might give you better soundstage since the tweeter placement is more flexible. Though honestly, a good coaxial speaker around 60-80 watts RMS could be sufficient if you're not going for audiophile-level sound.

Why are 6x9 speakers recommended for Plymouth Horizon rear doors?

The 6x9 size provides better bass response than smaller speakers due to the larger cone area. They can typically handle 20-30% more power than 5.25 inch speakers, usually around 100-150 watts RMS. The oval shape fits the available space efficiently in the Plymouth Horizon rear door panels. Full-range 6x9s work well for rear fill, though some prefer coaxials for better high-frequency dispersion.

What impedance should I look for in Plymouth Horizon replacement speakers?

Standard 4-ohm speakers work best with most factory and aftermarket head units. The Plymouth Horizon's electrical system handles 4-ohm loads without issues. Some 8-ohm speakers might sound quieter since they draw less current, but they're less common anyway. Avoid 2-ohm speakers unless your amplifier specifically supports that impedance - could cause overheating.

Do I need an amplifier for Plymouth Horizon speaker upgrades?

Not necessarily for basic upgrades. Most aftermarket head units provide 18-25 watts RMS per channel, which is adequate for 5.25 inch and 6x9 speakers in a smaller car like the Plymouth Horizon. An amplifier becomes worthwhile if you want serious volume or are installing higher-end component systems. The car's cabin size means you don't need massive power to fill the space.
