Dodge Diplomat Speaker FAQ

What speakers should I replace first in my Dodge Diplomat for better sound quality?

Replace the 6 x 9 inch rear deck speakers first. These handle most of your bass and midrange output - around 80% of what you actually hear while driving. The dashboard 3.5 inch speakers mostly fill in treble frequencies above 3kHz. You'll get more noticeable improvement from upgrading the larger drivers since they move more air. The rear deck location also tends to accumulate more wear from heat and vibration over the years.

Can I install component speakers in the Dodge Diplomat dashboard location?

Not really practical with 3.5 inch openings. Component systems need separate tweeter mounting which would require custom work in the Diplomat's dashboard. Stick with coaxial or full-range speakers for the dash position. The small size already limits bass response below 200Hz anyway. Your 6 x 9 rear speakers should handle the heavy lifting for midrange and lower frequencies. Consider higher sensitivity coaxials - maybe 90dB or better - to get decent output from the dashboard position.

What's the difference between coaxial and triaxial speakers for my Dodge Diplomat rear deck?

Triaxial adds a third driver - usually a small tweeter or super-tweeter for frequencies above 10kHz. Coaxial typically has just the woofer and tweeter. The triaxial might sound more detailed in the upper range, but... honestly, the difference isn't always worth the extra cost. Your car's interior acoustics matter more than that extra driver. Road noise masks a lot of the subtle high-frequency detail anyway. Focus on finding 6 x 9 speakers with good midrange response around 1-3kHz where vocals live.

How many watts can the Dodge Diplomat speaker locations handle?

The 6 x 9 rear deck can probably handle 50-75 watts RMS safely. Maybe more if you reinforce the mounting area. The 3.5 inch dashboard speakers... maybe 20-30 watts RMS maximum. These small drivers overheat quickly with too much power. Your factory radio probably outputs 15-20 watts per channel anyway. If you're adding an amplifier, watch the power levels carefully. The Diplomat's thin metal speaker grilles don't provide much protection from blown drivers.

Should I upgrade to 4-ohm or 8-ohm speakers in my Dodge Diplomat?

Stick with 4-ohm speakers for both locations. Most aftermarket head units expect 4-ohm loads and will deliver more power compared to 8-ohm speakers. The Diplomat's electrical system can handle the slightly higher current draw. 8-ohm speakers might sound quieter unless you're running a separate amplifier designed for higher impedance loads. Check your radio's specifications though - some older units actually prefer 8-ohm loads for better stability.
