About the Infinity Reference REF-9630cx

Classic components
Classic components
One thing's for sure — our customers love Infinity's Reference Series speakers. Year after year, car after car, options like this Reference Series REF-9630cx 6"x9" component speaker system remain a popular choice for replacing factory speakers because of their competitive pricing and superb sound.
Edge-driven dome tweeters
With this component system, you'll gain exceptional clarity and imaging, thanks to separate 3/4" edge-driven textile dome tweeters that subdue any harshness in the high-frequency range. Infinity includes external crossovers that give you push-button tweeter attenuation for a "brightness" quick fix.
Bigger woofers
The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you'll enjoy powerful sound every mile you drive. Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker's impressive performance.
Bring on the power
You can power these speakers with up to 125 watts of RMS power — they'll work well with an external amplifier, but they're also a good match for a factory radio or aftermarket stereo. Plus, these 3-ohm speakers combine with the speaker wire in your vehicle so your car stereo sees actual 4-ohm impedance, so you get a little more volume out of your system.

Woofers
Plus One+ Woofer Cones: Each speaker uses a larger cone than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.
Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.
Tweeters
Material: Each tweeter features a 3/4" edge-driven textile dome for smooth, accurate highs.
Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:
- I-Mount: The tweeters can be surface- or flush-mounted
with Infinity's innovative I-Mount system:
- Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
- Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount housing and plastic locking nut. Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
- Starfish Mounting Brackets: The Starfish mounting
brackets allow the tweeters to be installed in factory locations behind the
grilles:
- Bottom Mount: Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
- Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
- Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under a half inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Crossovers
Selectable Tweeter Output Level: Each 2-way crossover allows you to select the tweeter output level according to system requirements and personal preference; the tweeter level can be set to +3 dB or 0 dB.
Connections: The crossover inputs and outputs are screw terminals; they will accommodate bare wire or spade connectors up to 0.31" wide. There are four mounting holes in each crossover.
Dimensions:
- Width: 4"
- Height: 1-1/8"
- Depth: 3-1/4" (plus wire)
Specifications
High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.

These speakers sounds 10x better than the factory alpine my 2022 Dodge Ram came with. the tweeters for the dash corners and the woofer for the door. truck is sounding much better!
