  • Our take on the Alpine R2-W8D4

    The Alpine R2-W8D4 is an 8-inch dual 4-ohm subwoofer from Alpine's R-Series, rated at 350 W RMS and 1,000 W peak. Its dual voice coils let you wire it to a 2-ohm or 8-ohm load, so it fits a range of amps and small sealed or ported enclosures. It is built for tight, punchy bass in compact spaces rather than deep, high-output boom. Compared with larger 10- and 12-inch subs it gives up some low-end extension, but it needs far less airspace and power.

    What reviewers say

    Owners of R-Series subs generally describe clean, controlled bass for the size and solid build. The 8-inch model is praised for fitting tight spaces, while some note it will not match bigger subs for depth.

    What people mention
    • Bass outputMixedOwners say it delivers punchy, controlled bass but not the depth of larger subs.
    • SizePraisedBuyers like that it fits small enclosures and tight install spaces.
    • BuildPraisedReviewers describe the construction as solid and durable.
    • Power needsMixedIts low sensitivity means it needs a capable amplifier to reach its potential.

    Questions and answers

    Can I wire the R2-W8D4 to 2 ohms?
    Yes. The dual 4-ohm voice coils wire in parallel for a 2-ohm load or in series for 8 ohms. Match the final load to your amplifier's rating.
    How much power does it need?
    Alpine rates it at 350 W RMS, so an amplifier delivering roughly that into its final impedance is a good match. More headroom is fine if gains are set correctly.
    What size enclosure does it need?
    It is an 8-inch sub designed for small sealed or ported boxes. Follow Alpine's recommended enclosure volume and tuning for the R2-W8D4 rather than guessing.
    Is it a good upgrade over a stock sub?
    In a car with a weak factory sub, it adds noticeably tighter, louder bass without taking much space. It will not deliver the deep output of a 12-inch sub.
    Can I use it in a boat?
    No. Alpine does not rate this sub for marine use, so it is best kept in a car or truck.
    Where is the Alpine R2-W8D4 cheapest?
    At Best Buy, for $299.95, as of our latest check.
