About the JBL 631
3-way sound at a strong price
3-way sound at a strong price
Bring on the big fun of being there live, but leave off the big price tag — that's the idea behind JBL's Concert Series car speakers. Their Concert 631 6-1/2" 3-way speakers deliver a strong sound with a striking design, accented by JBL's "exclamation point" logo on the tweeter. And the speaker's patented Plus One™ structure extends the surface area of the polypropylene woofer cone to give you a better low-frequency experience.
A match for any system
These 3-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get even better results feeding them power from an outboard amp.
Grilles are not included; the factory grilles should be suitable for most applications.

Features
Plus One+ Woofer Cones: Each speaker uses a cone larger 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.
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.
Mounting: Without an adapter, these speakers fit standard 6¾" applications. Given their required cutout, they will also fit many 6½" applications without an adapter, but new screw holes must be drilled. Please enter your vehicle information to confirm fit.
