Volvo 740 Speaker FAQ

Which speakers should I replace first in my Volvo 740 for the biggest sound improvement?

Start with the 5.25 inch rear deck lid speakers. These handle most of your mid-range frequencies and bass response. The larger surface area means more air movement, which translates to fuller sound. Front door 4 inch speakers come second since they're your primary stereo imaging source. Rear door panels... honestly they're mostly fill speakers anyway.

Can I install component speakers in all Volvo 740 locations?

The rear deck lid and front door panels support component systems - you can separate your tweeters from woofers. This gives you better sound staging since you can aim tweeters toward your ears. Rear door panels only accept coaxial or full-range speakers though. The space constraints just don't allow for separate tweeter mounting. Component systems typically need 50-100 watts RMS to really shine.

What's the difference between coaxial and full-range speakers for my Volvo 740?

Coaxial speakers have a tweeter mounted directly on the woofer cone - you get highs and mids from one unit. Full-range speakers try to reproduce all frequencies from a single driver without a separate tweeter. Coaxials usually sound clearer in the 2-20kHz range. For the 4 inch locations in your Volvo 740, coaxials make more sense since the small size already limits bass response below 80Hz anyway.

Do the 4 inch speakers in my Volvo 740 doors need special impedance matching?

Most aftermarket 4 inch speakers run at 4 ohms, which should match your factory head unit output. If you're running an aftermarket amplifier, you might want to verify the total impedance load. The front and rear 4 inch positions can handle 20-40 watts RMS each. Going higher might stress the mounting points since the doors weren't designed for heavy bass loads.

Should I upgrade the rear deck speakers or door speakers first in my Volvo 740?

The 5.25 inch rear deck position gives you the most bang for your buck. Larger cone area means better low-frequency response, probably down to 60-70Hz with a decent speaker. The 4 inch door speakers are important for imaging but they're naturally limited below 100Hz. If you're keeping the factory head unit, focus on speakers with sensitivity ratings around 88-92dB since you won't have much power to work with.
