Full details
The KICKER KS-Series 3.5-inch speakers are ideal for automotive enthusiasts looking to upgrade their factory dashboard or door-mounted sound system without extensive interior modifications. These speakers excel at delivering crisp, detailed high frequencies and a rich, balanced midrange, though users should note their 3.5-inch size is designed primarily for fill or specialized locations rather than deep bass production. Featuring a compact, thin-mount design and integrated neodymium magnets, they provide professional-grade acoustic clarity and robust power handling for a significantly improved daily listening experience.

FAQs
Will these speakers fit my specific vehicle?
These are 3.5-inch speakers; they fit most vehicles with standard 3.5-inch dash locations, but you should check your vehicle manual for exact fitment specifications.
Do I need an external amplifier for these speakers?
No, they are designed to run efficiently off standard factory or aftermarket head unit power, though an amplifier can offer further clarity.
Are mounting screws included?
Yes, necessary mounting hardware is typically included to facilitate a standard installation.
Can these be used as rear fill speakers?
Yes, they can be used in rear pillar or side panel locations if your vehicle utilizes 3.5-inch rear speakers.
What is the frequency response range?
These speakers handle a frequency range of 80Hz to 20kHz.
Is a grille included with the speakers?
Many installations use the factory grilles, but you should verify the contents list for your specific retail package as some include basic mesh covers.
Troubleshooting
Sound is distorted at higher volumes.
Check your head unit settings to ensure a high-pass filter is active for the 3.5-inch speakers to remove frequencies below 80-100Hz.
No sound output from the speaker.
Verify the wiring harness connections and ensure the speaker terminals are fully seated; check the head unit balance/fader settings.
Rattling noise heard at certain frequencies.
Inspect the mounting screws to ensure they are tight and verify the speaker grille is securely fastened back into place.
Pros and Cons
Pros
- Easy installation due to the shallow-mount profile
- Superior high-frequency clarity compared to factory-installed drivers
- Compact neodymium magnets allow for a smaller physical footprint
- Durable construction designed for the automotive environment
Cons
- Limited low-end frequency response due to the 3.5-inch woofer size

- Requires proper high-pass filtering to avoid distortion at very high volumes
Setup, Compatibility & Care
Before installation, verify the speaker opening in your dashboard or door panel matches the 3.5-inch form factor. Ensure that you have the correct vehicle-specific wiring harness adapter, as this will allow for a plug-and-play installation without cutting factory wires. When mounting, ensure the included hardware is tightened securely to prevent vibration or rattling. Maintenance is minimal: keep the speaker grilles clean of dust using a soft, dry cloth. Avoid using liquid cleaners directly on the speaker cones, as moisture can damage the structural integrity of the diaphragm over time.
