Audio360 AD6510P 6.5" 4-Way Coaxial Car Speakers

The Audio360 AD6510P is a 6.5-inch 4-way coaxial car speaker designed for vehicle audio upgrades where space and straightforward fitment matter. Its compact format is suited to many door-panel, rear-deck, and custom speaker locations that accept a 6.5-inch driver. It is intended for listeners who want to replace factory speakers or build out an aftermarket sound system.

This model combines a 4-way coaxial layout with a 4-ohm nominal impedance for use with compatible aftermarket head units and amplifiers. The 92 dB sensitivity rating supports efficient output from modest-power sources while remaining suitable for amplified systems. Its sound character is aimed at strong midbass presence and clear everyday playback.

The AD6510P is rated at 650 watts maximum power and 325 watts RMS per speaker. These published ratings make proper amplifier gain setting especially important for reliable operation. Match the system carefully and avoid driving the speakers into audible distortion.

An injection-molded cone and rubber edge form the core of the speaker's woofer assembly. This material combination is designed to provide a durable moving surface while helping control cone movement. The coaxial construction keeps the multi-driver arrangement in a single speaker location, which can simplify an upgrade where separate tweeter mounting is not planned.

With a stated 2.76-inch mounting depth and 5.63-inch cutout diameter, the AD6510P can be considered for installations with limited rear clearance. Verify the vehicle's factory opening, available depth, mounting-hole pattern, and window or mechanism clearance before purchase. It can serve as part of a front- or rear-speaker upgrade when paired with compatible wiring and source equipment.

• 4-Ohm Impedance: Works with many aftermarket head units and amplifiers.

Design & Installation

The AD6510P uses an injection-molded cone with a rubber edge for a durable speaker assembly. Its 4-way coaxial design places the speaker elements together in a compact footprint. This makes it practical for installations that do not have separate locations for dedicated tweeters.

Confirm that your vehicle supports a 5.63-inch cutout and at least 2.76 inches of mounting depth before installation. Use appropriate vehicle-specific brackets or adapters when required, and check clearance behind the speaker before fastening it in place. For amplified use, set gains conservatively and use compatible 4-ohm-capable equipment.
