Alphasonik AS68 6x8 350W 3-Way Car Speakers - Clear, Powerful Sound

In this review the Alphasonik AS68 6x8 loudspeakers are presented as a practical upgrade for drivers who want stronger, clearer sound without replacing factory wiring or enclosures. The bottom line: these speakers deliver a convincing balance of power and midrange clarity, and they are easiest to recommend to people seeking a straightforward replacement or budget-conscious upgrade. The review focuses on real-world fit, sound character, and installation ease to help car owners decide if these are the right coaxial speakers for daily driving or road trips.

Key Features

• Power handling: Rated to handle up to 700 watts per pair, these speakers give clearly louder output than common factory units for driving music with more authority.
• Wide frequency response: With a range from 28 to 22,000 Hz the AS68s reproduce low mids and upper treble well, which helps vocals and guitar lines feel present in mixed playlists.
• 3-way coaxial design: The integrated tweeter and midrange deliver a fuller sound from a single mounting location, simplifying installs while improving detail.
• 4 ohm impedance: The low impedance optimizes power transfer from most car head units and amplifiers, so the speakers can reach good volume without wasting energy.
• Shallow mounting depth: A 2.32 in mounting depth and included hardware make these speakers easy to fit into many factory openings without modification.
• Consistent performance: Customers report stable, distortion-free playback at higher volumes, which makes these suitable for daily driving and longer trips.

Who It's For

The Alphasonik AS68 pair is best for drivers who need a direct replacement for 6x8 openings and want a noticeable step up from stock speakers without adding a separate amp. They are particularly useful for owners who value clear midrange and consistent performance at elevated volume.

These are less appropriate for audiophiles who demand extreme low-bass extension or studio-level accuracy; if deep sub-bass or critical listening is the priority, a dedicated component system with a subwoofer and external amplification would be a better investment.

Pros & Cons

Pros

• Good power capacity for the price, allowing louder, cleaner playback than many stock units.
• Balanced frequency coverage from 28 to 22,000 Hz provides clear mids and present highs for most music genres.
• Shallow 2.32 in mounting depth and included hardware make installation straightforward in many vehicles.
• 4 ohm impedance optimizes power use from typical car stereos, improving efficiency and volume control.

Cons

• While midrange is durable and clear, the package lacks the deep sub-bass impact of a system with a dedicated subwoofer.
• Enthusiast listeners expecting studio-like precision may prefer component speakers with separate crossovers and more detailed imaging.

Frequently Asked Questions

Will these fit my car's existing 6x8 openings?
In most cases yes; the 2.32 in mounting depth and included hardware let these drop into common factory openings without modification.

Do they need an external amplifier to sound good?
They sound better with added power but will work well with many factory head units because of the 4 ohm impedance and efficient design.

Are these speakers suitable for bass-heavy music?
They reproduce low mids well, but for true deep bass a dedicated subwoofer is recommended alongside these speakers.
