For most Scion xB owners replacing factory door speakers, the Kenwood 6-1/2″ 300W Max (60W RMS per Pair) is the strongest starting point because it combines a 6.5-inch format, 4-ohm impedance, 60 watts RMS per pair, and a listed top-mount depth of 1-11/16 inches. It is a more useful match for a speaker-only upgrade than the several head units in this selection, which add CarPlay or Android Auto but do not replace the xB’s speakers.
Pros
- The 2-way design combines a main cone with a separate 1-inch balanced dome tweeter
- Polypropylene cones and treated cloth surrounds are specified
- The speakers provide a listed 40–22,000 Hz frequency response
- 90 dB sensitivity and 4-ohm impedance are clearly stated
Cons
- The listed 1-11/16-inch top-mount depth and 4-7/8-inch cutout dimension should be checked against the installation location

What matters when choosing Scion xB speakers
Speaker fit is the first filter. The listings identify several products as 6.5-inch replacements, while the Pioneer F-Series TS-F6935R uses a 6 x 9-inch frame. A diameter label alone does not confirm door depth, mounting height, grille clearance, adapter requirements, or connector compatibility for every xB model year. Before ordering, compare the speaker opening, available depth, factory plug, and mounting points with the vehicle and the replacement speaker.
Power handling also needs careful interpretation. Peak or maximum wattage is not the same as continuous RMS power. The Kenwood Sport Series lists 60 watts RMS per pair, while the Pioneer F-Series TS-F1634R lists 25 watts nominal per speaker. Those figures are more useful for judging amplifier pairing than a large maximum-wattage number. Factory radios generally favor speakers that can produce useful output without demanding a powerful external amplifier, but the listings covered do not document the Scion xB factory radio’s output.
Sensitivity is another relevant specification. The Kenwood KFC-1666S lists 92 dB, the Kenwood Sport Series lists 90 dB, and the Pioneer TS-F1634R lists 88 dB. Higher sensitivity can make a speaker easier to drive from a modest head unit, but it does not by itself establish better bass, clarity, or durability.
Prices are observations and can change. Confirm the current price, fitment, included hardware, and seller terms before buying. CarTechTalk may earn a commission from qualifying purchases made through commercial links in this article. That does not change the compatibility cautions or the reasons to avoid a particular model.
Best Scion xB speaker choices
Best general replacement: Kenwood 6-1/2″ 300W Max (60W RMS per Pair)
The manufacturer lists a polypropylene cone, treated cloth surrounds, 1-inch balanced dome tweeters, 4-ohm impedance, 90 dB sensitivity, and a 40 to 22,000 Hz frequency response. Its 6.5-inch format and listed 1-11/16-inch top-mount depth give an installer more useful fitment information than some of the other speaker listings.
This is the most balanced choice for an xB owner who wants a conventional coaxial door-speaker replacement and plans to use the existing radio or a modest aftermarket receiver. The two-way layout keeps the installation simpler than a component system, while the stated RMS figure provides a clearer power reference than the 300-watt maximum number.
Drawback: The listing does not explicitly confirm Scion xB fitment or include a vehicle-specific harness. Avoid if: you need guaranteed plug-and-play xB compatibility or do not want to verify depth and mounting details first.
Best low-cost 6.5-inch option: Pioneer F-Series TS-F1634R 6.5″ 2-Way Coaxial Car
At the listed $29.00, the Pioneer TS-F1634R is the least expensive speaker-only option here. The manufacturer lists a 6.5-inch two-way coaxial design, 4-ohm impedance, 25 watts nominal power per speaker, 88 dB sensitivity, and a conventional black finish.
Its role is straightforward: replace aging 6.5-inch speakers without adding an amplifier or changing the rest of the system. The 4-ohm rating is a conventional match for many automotive audio systems, but the listing does not verify the output or compatibility of a particular xB factory radio.
Drawback: Its 88 dB sensitivity and 25-watt nominal rating are less favorable on paper for a low-powered factory system than the higher-sensitivity Kenwood options. Avoid if: you prioritize maximum volume from the original radio or expect a substantial bass upgrade without adding amplification.
Best for higher listed sensitivity: Kenwood KFC-1666S 300 Watts 6.5″ 2-Way Car Coaxial
The Kenwood KFC-1666S lists a 6.5-inch polypropylene woofer cone, a 1-inch balanced dome tweeter, 4-ohm impedance, 30 watts rated input power, 300 watts peak input power, and 92 dB sensitivity. The pair is listed at $38.00.
That 92 dB figure makes this a logical candidate for an xB owner retaining a factory radio and wanting a speaker that does not appear demanding on paper. The sound-field-enhancer feature is part of the product name, but the listing does not explain its construction or quantify its effect, so it should not be treated as a guarantee of a wider soundstage.
Drawback: The listing does not provide mounting depth, cutout dimensions, or Scion xB fitment details. Avoid if: you need confirmed door clearance before purchase or cannot verify the opening against the speaker dimensions.
Best vehicle-specific package: Harmony Audio 6.5 Inch Speakers with Harness Fits
Harmony Audio lists this R65 package as a pair of OEM speaker replacements for the Scion xB 2004 to 2014, and the product name identifies an included harness. At $104.95, it costs more than the generic 6.5-inch pairs, but the vehicle-specific positioning may reduce connector work and uncertainty for owners within that model-year range.
This is the better fit for an xB owner who values a stated vehicle application and wants to avoid cutting the factory wiring. The compatibility range stops at 2014 in the listing, so owners of a 2015 xB should not assume the same fitment.
Drawback: The published description gives no power-handling, sensitivity, frequency-response, or mounting-depth specifications. Avoid if: you need to match speakers precisely to an amplifier or want detailed acoustic specifications before choosing.
Best when an amplifier is part of the plan: Kicker DSC65 Speaker Replacement and HA-A400.4 Amp
This Harmony Audio bundle includes two Kicker DSC65 speakers and a Harmony HA-A400.4 amplifier. The listing identifies it as a factory-speaker replacement bundle for the Scion xB 2004 to 2014 and lists a price of $267.99.
The bundle makes sense for an owner planning a larger system change rather than a simple speaker swap. Adding an amplifier changes the installation requirements: power wiring, grounding, signal integration, fuse selection, gain setup, and space for the amplifier all become relevant. None of those installation details are provided in the listing, so professional installation may be appropriate for buyers without car-audio wiring experience.
Drawback: It is the most expensive option listed and provides limited speaker specifications in the available description. Avoid if: you only need replacement speakers for the factory radio or want a quick, low-complexity installation.
Best package with a basic Bluetooth receiver: BOSS Audio Systems 638BCK Car Stereo, Bluetooth
This package combines a Bluetooth receiver with 6.5-inch two-way full-range speakers. The manufacturer lists USB, auxiliary, AM/FM, Bluetooth, front and rear preamp outputs, and 50 watts x 4 maximum receiver power. The speaker listing states 250 watts per pair, 84 dB sensitivity, and an 80 Hz to 18 kHz frequency response.
It is aimed at an xB owner who needs both a replacement receiver and speakers, not someone seeking speakers alone. Bluetooth can handle calls and wireless music, but this receiver is not listed with Apple CarPlay or Android Auto. The manufacturer also says an amplifier is recommended to ensure the speakers are well powered.
Drawback: The receiver lacks a listed CarPlay or Android Auto feature, and the speakers’ 84 dB sensitivity is the lowest among the speaker specifications provided here. Avoid if: smartphone projection or strong output from a factory-level radio is a priority.
Best for a confirmed 6 x 9 installation: PIONEER F-Series TS-F6935R 6″ x 9″ 3-Way Coaxial
The Pioneer TS-F6935R uses a 6 x 9-inch three-way design with a woofer, midrange driver, and tweeter. The manufacturer lists 230 watts maximum, 30 watts nominal, 4-ohm impedance, and 87 dB sensitivity. The listing also says an external amplifier is required and recommends professional installation unless the buyer has car-audio experience.
This option belongs on the shortlist only if the xB’s mounting location accepts a 6 x 9-inch speaker or an appropriate adapter. Its three-way construction may appeal to an owner pursuing a more elaborate system, but the listing does not confirm Scion xB fitment. The 6 x 9 size should never be treated as interchangeable with a 6.5-inch door opening.
Drawback: The manufacturer states that an external amplifier is required, and Scion xB compatibility is not listed. Avoid if: you want a factory-radio replacement with no amplifier or adapter work.
Head units in this selection are not speaker replacements
Three listings focus on modern receiver features rather than replacement speakers. Android 13 Car Radio for Scion FR-S 2013-2016,tC lists compatibility with the Scion xB 2004 to 2015, wireless and wired CarPlay, Android Auto, a 7-inch screen, and a built-in 4 x 50-watt amplifier. The listing cautions buyers to check the vehicle year, dimensions, and console shape.
The [6+128G]-8Core Car Stereo for Toyota Scion xB lists wireless CarPlay, Android Auto, a 32-band DSP, steering-wheel-control support, and compatibility with xB models from 2007 to 2019. The (8Core + 64GB) Car Radio Stereo for Toyota Scion lists a 7-inch QLED display, wireless CarPlay and Android Auto, Bluetooth 5.2, and xB compatibility from 2007 to 2019.
These may be relevant if the real goal is to modernize the dashboard, but they do not replace the door speakers. A new receiver can change equalization, source quality, connectivity, and available amplifier power, yet it cannot correct a damaged speaker or create the same installation result as a speaker replacement. Verify dashboard fit, wiring, steering-wheel-control retention, backup-camera integration, and model year separately.

| Harmony Audio 6.5 Inch Speakers with Harness Fits | 6.5-inch pair | – |
| Kicker DSC65 Speaker Replacement and HA-A400.4 Amp | Speaker and amplifier bundle | – |
| BOSS Audio Systems 638BCK Car Stereo, Bluetooth | 6.5-inch, two-way speakers | 250W per pair; receiver 50W x 4 maximum |
| PIONEER F-Series TS-F6935R 6″ x 9″ 3-Way Coaxial | 6 x 9-inch, three-way | 30W nominal, 230W maximum |
Choose the Kenwood Sport Series for the most balanced generic 6.5-inch specification set. Pick the Harmony Audio pair when the 2004 to 2014 xB fitment and harness matter more than detailed published specifications. The Kicker and amplifier bundle is for a full system upgrade, while the Pioneer 6 x 9 belongs only in a confirmed 6 x 9 installation.
Do not buy anything in this guide if you are looking for component speakers with separate tweeters, a subwoofer, a complete sound-deadening plan, or a documented fit for a different vehicle. Instead, look for a component set or vehicle-specific kit that states the required size, depth, brackets, wiring adapters, and amplifier requirements for your exact xB year.

Final verdict
The Kenwood 6-1/2″ 300W Max (60W RMS per Pair) is the best starting point for the typical Scion xB speaker replacement because its 6.5-inch size, 4-ohm impedance, RMS rating, sensitivity, and mounting depth are all stated. Buyers who want the lowest entry price can choose the Pioneer TS-F1634R, while the Kenwood KFC-1666S is appealing for its listed 92 dB sensitivity.
Fitment can outweigh paper specifications. For a 2004 to 2014 xB, the Harmony Audio package offers the clearest vehicle-specific positioning and a harness. If the project includes an amplifier, the Kicker bundle is the more complete route, but it carries greater cost and installation complexity. Confirm the exact xB year, mounting dimensions, wiring, and power needs before ordering, and treat the head units as separate CarPlay and Android Auto upgrades rather than speaker replacements.
