  • Our take on the Skar Audio SDR-8 8" 700 Watt Max Power Car Subwoofer

    The Skar Audio SDR-8 is an 8-inch car subwoofer rated at 350 watts RMS and 700 watts peak, with a dual 2-ohm voice coil. It is built for small sealed or ported enclosures where space is tight, and the dual 2-ohm coils let you wire to a 1-ohm or 4-ohm load depending on your amplifier. It sits in Skar's budget SDR line, below the beefier EVL and ZVX models, so it trades some excursion and power handling for a lower entry point. Owners of compact cars and truck cabs use it for added low end without giving up cargo space.

    Pros
    • Dual 2-ohm coils wire to 1 ohm or 4 ohms
    • Handles 350 watts RMS, enough for most small amps
    • 8-inch frame fits shallow, space-limited enclosures
    • Skar's SDR line is a known budget option for first bass builds
    Cons
    • 700 watts is a peak figure; plan around 350 RMS
    • 8-inch cone moves less air than 10- or 12-inch subs
    • Needs a properly built enclosure to sound its best
    • Not a substitute for Skar's higher lines if you want heavy output

    What reviewers say

    Owner feedback on the SDR line is generally positive for the money, with people noting solid output from a small driver when it is fed clean RMS power in a good box. Complaints tend to center on expectations set by the peak rating and on output limits versus larger subs.

    What people mention
    • OutputMixedOwners say it delivers solid bass for an 8-inch in a small box but cannot match larger drivers.
    • Power handlingMixedPeople note the 350-watt RMS figure is the real limit and the 700-watt peak rating misleads.
    • Voice coilsPraisedThe dual 2-ohm coils are seen as flexible for wiring to 1 or 4 ohms.
    • EnclosureCriticisedReviewers say results depend on a well-built sealed or ported box.

    Questions and answers

    Is 700 watts the real power rating?
    No. 700 watts is peak. The RMS rating is 350 watts, and that is the number to match your amplifier to.
    What impedance can I wire it to?
    The dual 2-ohm voice coils wire in parallel to 1 ohm or in series to 4 ohms. Check that your amp is stable at the load you choose.
    What size enclosure does it need?
    It is an 8-inch driver, so it fits small sealed or ported boxes. Follow Skar's recommended box volume for the SDR-8 rather than guessing.
    Is it good for a first bass setup?
    Yes, if you want modest bass in a small space and have an amp that makes around 350 watts RMS. It is not a heavy-output sub.
    How does it compare with Skar's larger subs?
    It moves less air than 10- or 12-inch models in the SDR line and far less than the EVL or ZVX lines. Pick it when space matters more than maximum output.
    Where is the Skar Audio SDR-8 8" 700 Watt Max Power Car Subwoofer cheapest?
