BOSS Audio Systems NX694 6x9 Inch Car Door Speakers — 4-Way Coaxial, 800W Pair, Black

Upgrade your car audio with a pair of BOSS NX694 speakers designed to balance punchy lows, defined mids, and crisp highs in a single coaxial assembly. Built with a polypropylene cone, rubber surround and a stamped steel basket, the NX694 set fits many factory door locations while offering higher output and broader frequency coverage than typical OEM speakers. The package includes grills and dimensions to help verify fit, and BOSS backs the product with a three-year platinum online dealer warranty when purchased through Amazon.

How will these speakers change the sound inside my car?

The NX694 converts stereo source material into fuller, more dynamic playback compared with standard factory speakers. A dedicated midrange and dome tweeters improve vocal clarity and instrument separation while the larger 6x9 cone delivers stronger low-frequency presence without needing a separate enclosure.

• 4-way coaxial design separates bass, mid, and treble for cleaner audio.
• Frequency response 45 Hz–20 kHz reproduces wide-range content.
• 89 dB sensitivity improves perceptible loudness with moderate power.
• Max power handling 800 W per pair accommodates aftermarket amplifiers.

Will the NX694 fit my car door and what are the physical specs?

These speakers are sized to fit many common 6x9 mounting locations, but measure your factory opening before ordering. The NX694 pair includes grills and detailed dimensions so you can confirm compatibility and required clearance for tweeter or grill protrusion.

• Overall speaker w/grill: 10.2" x 7.52" (259 x 191 mm).
• Installation hole: 8.55" x 5.85" (217 x 149 mm); mounting depth: 3.47" (88 mm).
• Tweeter protrusion 0.44" (11 mm); grill protrusion 2.3" (33 mm).
• Weight: 10 lbs per pair; outer motor diameter 4.97" (126 mm).

Do these speakers need an external amplifier or special wiring?

The NX694 can be used on factory speaker outputs, thanks to a nominal impedance of 4 ohms and decent sensitivity, but to unlock maximum headroom and low-frequency control pair them with an aftermarket amp. If keeping the stock head unit, ensure gain is set conservatively; professional installation is recommended for safe wiring and optimal tuning.

• Nominal impedance: 4 ohms — compatible with most car stereos and amps.
• Built-in 6 dB/oct high-pass filter helps protect mid/tweeter from deep bass when bridged.
• Max power suggests benefit from a dedicated amplifier for sustained loud playback.
• Professional installation recommended to avoid phase or wiring issues.

Who is this for? The BOSS NX694 pair is aimed at drivers who want a substantial upgrade over factory speakers without adding separate component sets or subwoofers. They suit audiophiles on a budget seeking fuller lows and clearer mids in sedans, trucks or SUVs that accept 6x9 mounts, plus installers and enthusiasts who pair speakers with aftermarket amplifiers for stronger performance. If you need wide frequency coverage in a single, door-mounted package and value durable materials and measurable specs, the NX694 is a practical choice.
