Gravity SGR654 6.5" 4-Way Full-Range Car Speakers

The Gravity SGR654 is a pair of 6.5-inch full-range car speakers intended for vehicles that use this common speaker size. Their 4-way design combines multiple sound-producing elements in each speaker to cover a broad portion of the audible range. They are a practical option for replacing worn factory speakers or building an entry-level car-audio system.

These speakers are specified with a 60 Hz to 20 kHz frequency response, supporting bass, midrange, and high-frequency content within one coaxial-style assembly. A 92 dB sensitivity specification indicates they are designed to produce useful output without requiring unusually high amplifier power. The 4-ohm impedance suits many conventional car-audio amplifiers and compatible head-unit speaker outputs.

Gravity rates the SGR654 at up to 400 watts maximum per speaker, or 800 watts maximum for the pair. Maximum-power figures are not the same as continuous RMS ratings, so amplifier selection should be based on conservative gain setting and clean, unclipped output. Proper power matching is especially important when using an external amplifier.

The speaker uses a moisture-resistant rubber surround and an anti-resonant stamped-steel basket. These construction details are intended to help the assembly tolerate vibration and typical automotive environmental conditions. Spade-style speaker terminals provide a straightforward connection point for vehicle speaker wiring.

With a listed mounting depth of 2-7/8 inches, the SGR654 should be measured against the available clearance behind the intended mounting location before installation. It can be used as a pair for front or rear speaker replacement where fitment permits. For a more complete system, it can be paired with a compatible amplifier, wiring, and a separate subwoofer if additional low-bass output is desired.

Key Features

• 6.5-Inch Speaker Size: Fits applications designed for 6.5-inch speakers when mounting clearance permits.
• 4-Way Full-Range Design: Uses a multi-element design to reproduce a broad frequency range.
• 800-Watt Pair Maximum: The pair is specified for up to 800 watts maximum power handling.
• 4-Ohm Impedance: Works with many compatible car stereo and amplifier speaker outputs.
• Moisture-Resistant Rubber Surround: Helps support durability in automotive listening environments.
• Stamped-Steel Basket: Provides a rigid mounting structure intended to limit unwanted resonance.

Design & Installation

The SGR654 combines a stamped-steel basket with a moisture-resistant rubber surround and a 2-3/8-inch voice coil specification. Its listed magnet size is 3-1/8 inches, and the speaker is specified at 92 dB sensitivity. The compact full-range format keeps the sound-producing elements together in a single 6.5-inch speaker assembly.

Confirm that the vehicle accepts a 6.5-inch speaker and has at least 2-7/8 inches of mounting-depth clearance before purchase. Connect the speakers with correct polarity using the spade terminals, secure them with suitable vehicle-specific hardware, and set amplifier gain carefully to avoid distortion. Mounting adapters, harness adapters, wiring, and other installation parts may be required depending on the vehicle.
