Peugeot 308 Speaker FAQ

What speakers should I replace first in my Peugeot 308?

Start with the front door panel speakers. The 6.5 inch midbass units handle the core of your listening experience, roughly 80 Hz to 5,000 Hz, and improving them tends to have the most noticeable impact on overall sound quality. The Peugeot 308 front doors are where most of the critical midrange information lives, so upgrading there before anything else probably makes the most sense. Rear speakers can wait.

Can I replace the 6.5 inch midbass speakers in the Peugeot 308 front and rear doors with any aftermarket unit?

Not exactly any unit. You want to match the impedance closely, typically 4 ohms, and keep power handling above the factory head unit output which is usually somewhere around 20 to 25 watts RMS per channel. Going too low on impedance risks stressing the head unit. The 6.5 inch mounting depth in the Peugeot 308 door panels can be tight, so checking the speaker's mounting depth before buying is worth doing. Adapters might be needed.

What does the 1 inch tweeter in the Peugeot 308 A-pillar actually do differently from the dashboard tweeter in older versions?

The A-pillar placement in the newer Peugeot 308 configuration aims the tweeter closer to ear level, which can improve stereo imaging. Dashboard tweeters, like those used in the earlier Peugeot 308 setup, tend to reflect sound off the windshield before it reaches you. Whether that difference is audible depends on your listening position and sensitivity. High-frequency reproduction above around 5,000 Hz is the primary job either way. The physics suggest A-pillar placement has potential advantages, though real-world results vary.

Is the 8 inch subwoofer in the Peugeot 308 cargo area worth replacing?

It depends on what you want from low-end response. Factory subwoofers in positions like the Peugeot 308 cargo area typically handle frequencies below 80 Hz but are often underpowered, sometimes only receiving 30 to 40 watts. An aftermarket 8 inch unit with a higher RMS rating, say 100 to 150 watts, paired with an external amplifier would likely improve output noticeably. The enclosure situation in the cargo area is something to think about too. Factory mounting solutions rarely account for proper box volume.

What is the 3.5 inch center dash speaker in the Peugeot 308 actually for?

It handles center-channel dialogue and vocal frequencies, generally from around 200 Hz up to 5,000 Hz or so. The Peugeot 308 center dash position is meant to anchor the soundstage between the two front speakers. Replacing it with an aftermarket 3.5 inch full-range unit rated at 4 ohms and at least 15 watts RMS should be straightforward. It matters more than people expect, particularly for voice clarity. Not always the first thing to upgrade, but not something to ignore either.
