Infinity Reference 5030CX / REF-5020CX 5-1/4" component speaker system (Proton S70 & Jimny PNP)

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-5030cx 5-1/4" 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 65 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.

Grilles are not included; the factory grilles should be suitable for most applications.
