Kicker's universal PS-series powersports speakers, the PS4, PS5250, PSC65, and PS69, share the same weatherproof construction, titanium tweeters, and neodymium magnets across four different sizes, from 4 inches up to a 6x9-inch oval. The real decision between them isn't sound quality, it's which one actually fits your existing cutout and how much power you want to feed it.
As an authorized Kicker dealer, we get asked "which PS speaker is best" more often than any other powersports question, and the honest answer is that they're built from the same design philosophy at different sizes. Here's the actual comparison, spec by spec.
Key Takeaways
- All four models share titanium tweeters, neodymium magnets, and a 4-ohm weatherproof design — construction quality doesn't change across sizes.
- Power scales with size: 50W RMS (PS4, PS5250) up to 90W RMS (PS69), so bigger isn't just about cutout diameter.
- Cutout size is the real deciding factor for most riders replacing an existing factory speaker — measure before choosing based on power alone.
- All four are currently priced within about $56 of each other ($103.96-$159.96), so budget isn't the main differentiator either.
- None include LED lighting or built-in amplification — all four are passive speakers requiring a separate amp or a head unit with sufficient built-in power.
Spec Comparison
| Spec | PS4 | PS5250 | PSC65 | PS69 |
|---|---|---|---|---|
| Size | 4" | 5.25" | 6.5" | 6x9" |
| Tweeter | 3/4" | 3/4" | 3/4" | 1" |
| Power (RMS) | 50W | 50W | 60W | 90W |
| Peak Power | 100W | 100W | 120W | 180W |
| Frequency Response | 100Hz–20kHz | 60Hz–20kHz | 40Hz–20kHz | 40Hz–20kHz |
| Cutout Size | 3-5/8" | 4-7/8" | 5-1/16" | 5/8" x 8-7/16" |
| Price (at time of writing) | $103.96 | $119.96 | $159.96 | $159.96 |
Sizing: The Decision That Actually Matters
If you're replacing an existing factory or aftermarket speaker, your current cutout size should drive this decision more than any spec on the table above. A PS69 doesn't sound categorically better than a PS4 in a way that justifies cutting a larger hole into your fairing or saddlebag — it's a different tool sized for a different existing opening. Measure your current cutout first, then choose the matching PS-series size, rather than picking the biggest one and hoping it fits.

What Changes Beyond Size
Frequency Response
Larger sizes extend lower: the PS4's 100Hz starting point is the highest (least bass) of the four, while the PSC65 and PS69 both reach down to 40Hz. If you're starting from scratch with no existing cutout, a slightly larger size buys real low-end improvement, not just a bigger number.
Tweeter Size
Three of the four share a 3/4-inch tweeter; only the PS69 steps up to a 1-inch tweeter, matching its higher overall power handling.
Power Handling
50W RMS on the two smallest sizes, 60W on the PSC65, 90W on the PS69. If you're pairing with a specific amp channel output, match the speaker's RMS rating to what your amp can realistically deliver per channel.
Installation Notes
All four are flush-mount, passive speakers with published cutout diameters (the PS69's oval cutout is listed separately from the round sizes). None include LED lighting, and none have a stated IP rating in these listings beyond general "weather-proof" or "weather-resistant" language, consistent with most of the powersports and marine speakers in this catalog that lack a formal numbered rating.
Amplifier Pairing
The KPX300.4 (45W RMS/channel at 4-ohm) comfortably covers the PS4 and PS5250 (50W RMS) with some headroom, and comes close to the PSC65's 60W RMS rating. For the PS69's 90W RMS rating, the KPX300.4 leaves real headroom unused; a higher-output amp would let that speaker use more of its actual capability. This is our own power-matching read, not an official Kicker-confirmed pairing.
Who Each Size Is For
Choose the PS4 or PS5250 for tight factory cutouts on smaller bikes and ATVs where physical space is the constraint. Choose the PSC65 for a standard round cutout with more low-end and power than the smaller sizes. Choose the PS69 specifically if you have (or are building around) an oval 6x9 cutout and want the highest output and lowest frequency extension in the PS-series line.
Honest Cons
No LED lighting on any size, unlike much of the marine catalog we've covered.
No formal IP rating published for any of the four models — general weatherproof language only.
Passive speakers only. All four need a separate amp or head unit with sufficient built-in power; none are self-amplified like the PowerCan line.
Frequently Asked Questions
Does a bigger PS-series speaker always sound better?
Not automatically — larger sizes extend lower in frequency response and handle more power, but if your cutout is small, forcing in a larger speaker isn't an option without modification. Match size to your actual mounting constraint first.
Can I mix sizes on the same vehicle?
You can, but matched sound quality is more consistent with the same model on both sides. Mixing sizes will produce audibly different output between speakers.
Do any of these include a built-in amp?
No — all four are passive speakers. For a self-amplified option, see the PowerCan Bluetooth speaker line in our Powersports collection instead.
Which one is the best value?
The PS4 and PS5250 offer the lowest entry price; the PSC65 and PS69 cost more but deliver more power and lower frequency extension. "Best value" depends on which cutout size you're actually working with.
Bottom Line
The PS4, PS5250, PSC65, and PS69 are the same PS-series build quality at four different sizes. Measure your cutout, match your amp's output to the speaker's RMS rating, and pick based on fit and power headroom, not an assumption that a bigger speaker automatically performs better for your setup.
