Focal Integration ISC 165 6-3/4" 2-way car speakers

You can aim the tweeter for better high-frequency dispersion.

Audiophile-grade engineering

Focal applies the same technology they use in their studio and audiophile-grade home systems to their Integration line of car speakers. Their Integration ISC 165 6-3/4" speakers use cones made of Polyglass, a material that combines the warm sound of cellulose with the strength of glass, for a woofer that plays accurately with no added resonances.

Adjustable tweeter

The Integration processed aluminum inverted dome tweeter features a built-in phase plug and wave guide, which act together to increase the power of high-frequency notes and improve the stereo soundstage. You can also tilt the tweeter for better imaging in many vehicles.

Integration speakers allow you to put Focal sound quality and construction into your vehicle without a lot of muss and fuss, so you can enjoy a dramatic jump in performance over your old speakers. Grilles are not included; factory grilles are appropriate for most installations.

Note: Focal describes this model as a 6-1/2" speaker. Most manufacturers designate this same frame size as a 6-3/4" speaker. For simplicity's sake we list it as a 6-3/4" speaker.

  • 2-way 6-3/4" speakers (pair)
  • Polyglass woofer with butyl rubber surround
  • processed aluminum inverted dome tweeter
  • 4-ohm impedance

Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Great sound

Crutchfield Customer Review (What's this?)

I recently installed these speakers in the rear doors on my 2015 Jeep Grand Cherokee, to compliment the Focal ISS690 component set, that I installed in the front doors. Although I don't drive from the back seat, the space between the seats and the side of the vehicle, as well as the space between the two seats themselves, presents an opportunity for the rear speakers to fill out the soundstage. I think these speakers do that quite well. The highs are "detailed", and the bass response is good.

Pros: Great sound, relatively easy install, although there isn't a lot of "meat" in the door structure to work with, when you drill the necessary holes to mount the speakers. (in a Jeep GC rear door, I mean) Measure carefully, and measure twice, before you start drilling.

Cons: As I mentioned in my review of the ISS690s, they are a bit pricey, and the supplied instructions are vague and almost non-existent. For what these speakers cost, I'd expect a little more detail in the owner's handbook, although a coaxial speaker installation is pretty straightforward.

Crutchfield Customer Review (What's this?)

I added these Focal's to my rear doors on my 2014 GMC Sierra Crew Cab and it has made a big difference in sound. The high's are crisp and clear while the mid-range adds a full sound to the rear seats.

Pros: Highly Recommended

Cons: N/A

These were meant to replace my Factory Boston Acoustics speakers. NOT IMPRESSED...AT ALL. The Factory speakers sound better and clearer. Sending these back and going with JL.



Welcome to hi end audio! Wow

Written by: JourneymanKGD from Denver, co on January 3, 2015

I bought these three months ago after hearing them at a lesser audio dealer. Holy $#*+. Best speaker I've bought. I can only imagine what their higher end stuff sounds like. really had no idea what I was missing. Bass you can feel, mids and highs put new life into my favorites. From my stock stereo. Couldn't be happier. Can't wait to get the 6x9's. And home speakers as well. Thank you crutch field and focal

Pros: Loud , clear, bass, and adjustable tweeters! Whole new level of sound quality. Handles brutal music with ease and , well. I LOVE them.

Cons: You will want more speakers from Focal, as I do. Addictive. Will drown out your other speakers. ( that's a good thing ).

These replaced the stock Rear door speakers in my optima. I could not be more impressed. The full sound and bass and not distorted at all. Great highs also, not ear piercing at all.

Pros: Retrofit without brackets or modification. And overall a great speaker for the price point.

Cons: Nothing

Product Research


Polyglass Cone: The woofer cone has a cellulose pulp base and is coated with a uniform deposit of hollow glass microballs. The addition of the Polyglass layer significantly increases the cone's rigidity without adding much weight. This combination takes advantage of the accuracy and neutrality of the hard outer surface, but maintains the superior damping characteristics of the cellulose pulp.

Surround: The butyl rubber surround is resistant to ultraviolet rays, temperature extremes, and humidity to add to the speaker's reliability and longevity.

Voice Coil: The voice coil is wound around a 1" diameter low-mass Kapton former, ensuring no coil deformation.

Inverted Dome Tweeter: The tweeter is an inverted aluminum dome, producing a broad sound stage. The tweeter is angled and rotates on its post, so it can be pointed toward the listener.

Size Classification Note: Crutchfield has traditionally referred to this size speaker as a 6-3/4", while some manufacturers, including Focal, call it a 6-1/2". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

Thanks for your question. Per manufacturer in this speaker set grilles are not included; factory grilles are appropriate for most installations. We would not have a grill specifically for this model. Hope that helps. [ Kenny  Feb 08, 2016 ]  Staff
