About the JBL 631

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.

Product Research

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.

Q
Ive put the JBL 631 Concert 6x9's in the front door of my 2018 Subaru CrossTrek Premium. Why does it say that these wont fit my car which has stock 6 1/2"'s in the back door? I'd like to keep the same JBL's (Concert series) in front and rear doors. I'm very happy with just the new 6x9's up front - cant wait to do tge rears! Thanks!

The limitation is the mounting height. The tweeters on those JBL Concert series 6 1/2" are a bit too tall and will hit the factory grill/ door panel. They are only off by less than 1/10" though so you may be able to make them fit. You can consult with one of our friendly product advisors here: https://www.crutchfield.com/I-rET1c290/S-SUliZgSTXG7/support/ContactUs.aspx
