Sony XS-680GS 6x8" coaxial pair

These Sony GS Series speakers are a 6x8-inch two-way coaxial pair built for car audio upgrades. Each unit combines a composite polypropylene woofer with a silk dome tweeter to cover the full frequency range in a single basket. The 4-ohm impedance matches standard head-unit and amplifier outputs. They suit drivers who want a direct factory-location replacement without adding external crossovers.

Sustained output and thermal handling

The speakers are rated for 40 watts RMS continuous power and can accept 230 watts peak for short transients. An 89 dB sensitivity rating means they produce strong volume levels from modest amplifier power. The progressive height rate spider and dynamic air diffuser help dissipate heat during extended listening sessions, keeping the voice coil stable when the system runs at higher output for long periods.

Frequency range and installation limits

Frequency response spans 50 to 24000 Hz, giving usable bass extension and detailed treble from the same driver. Top-mount depth measures 2-3/8 inches, so the basket fits many stock door cavities but will not clear shallower openings. Grilles are not included, so buyers must supply their own protection or use factory covers. This pair does not suit installations that require separate component tweeters or deeper bass than a 6x8 woofer can provide.

Questions about this item

Will the 89 dB sensitivity keep the 40 W RMS speakers cool during all-day use?

The 89 dB sensitivity means the speakers produce strong output with modest amplifier power, so they run efficiently and stay cooler during extended listening sessions.

What amplifier impedance must I already have to drive these 4 Ω speakers properly?

You need an amplifier or head unit rated for a 4 Ω load; most car stereos and aftermarket amps match this impedance directly.

Can I keep my factory tweeters and only replace the mid-bass with these 6×8″ coaxial units?

These are full-range 2-way coaxials with an integrated silk dome tweeter, so they replace both mid-bass and tweeter in one mounting location.
