About the JBL 8621F

JBL 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 8621F 6"x8" 2-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 Applications: JBL describes this speaker as a 6x8, but it also fits many 5x7 applications. Please enter your vehicle information to confirm fit.

Q
What size amp do I need with these speakers ?

You don't need an amp. I use these speakers off a stock head unit in a Ford and they sound great.Enter

If you're starting from scratch, factory specs are 50 watts. I installed them in my 2011 Ford Escape with factory radio and they sound great. I don't know what the stock amp is rated but it's plenty. That said, they will not blow you out but inside the vehicle with the windows up, they sound fine. They're clean on the highs, and defined and tight on the bass. Being two-ways the mid-range is slightly less satisfying, but only a tiny bit. To an untrained ear, the mids will sound just fine. I'm happy with them and would purchase them again.

Q
how will these 3 ohm speakers work with my factory head unit in a 2011 escape?
[ dale  Dec 14, 2019 ]

I installed 4 of these in my 2011 Escape with factory AM/FM radio and CD player. I also have Sirius XM. They sound so much better than factory speakers it's not worth mentioning. They have excellent highs and very powerful bass, so much so that I had to dial back the the BASS level. The mids are there, too, but depend on your source material. With CDs, these JBLs sound just fine, although at MAX volume, you are not going to rattle the windows. Installation is relatively easy if you watch the videos available and take notes. The only 'specialty' tool you will need is a trim removal tool. Everything else should be routinely available in a moderately stocked toolbox. For the money I can't imagine anything out performing these. They pair up nicely with the stock head unit and listening to the stereo is fun again. Don't forget the wire adapters!

Just changed my FOMO speakers to these JBL's. The stock radio is fine. Sounds great.
