Better components give you better detail

Each 6"x8" speaker sports a stiff polypropylene woofer cone that delivers strong drums and bass, along with clean reproduction of the midrange frequencies. Rockford Fosgate mounts the silk dome tweeter flush with the woofer so it'll fit in more vehicles while adding the excitement of strong high-frequency response. The built-in crossover network divides the frequencies going to each driver, so all your music plays faithfully.

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

Product Research

Features

Tweeters: Each speaker features a 1/2" Silk dome tweeter. The embedded design maintains the correct phase relationship between the tweeter and woofer, and doesn't add to the speaker's overall height.

Klippel Analysis: By using a state-of-the-art Klippel Distortion Analyzer, Rockford Fosgate engineers can optimize the speaker's motor structure, voice coil alignment, and suspension for the best possible performance and the lowest distortion.

Q
Good for motorcycle?
dan  Jun 18, 2022

A
The Rockford Fosgate R168X2 are not marine grade rated but if moisture or weather resistance is not a concern these would be great for a motorcycle. These have a frequency response of 51-20,000 Hz and can handle between 2-55 watts RMS.

Q
Will these also fit in the back doors of my 2013 f150?
harrison  Jan 14, 2022

A
I put these in the front doors. From what I have read they will fit the rear but I did not replace the rear so I'm not positive. For what it's worth I am really happy with them. I could not believe the difference they made over the stock speakers in my truck. My original Ford F-150 speakers were not that good and one of them was blown. Hope this helps. Jon
jon  Jan 14, 2022
A
They fit into my 1995 F350, so I would think so
michelle  Jan 14, 2022

I have a 2004 F150FX4 ex-cab and I have these speakers installed in both doors front and back. Good luck with your choice and Happy Holidays.

Q
Does it come with adapters for door wiring?
brenden  Nov 22, 2018
1 answer
A
These speakers just come with a set of universal wires to splice into whatever you have existing to convert to their slide terminal connectors. When I put my vehicle info in on crutchfield's site it showed me adapters for my specific application, and I used those instead.

Yes it does , when you order from cruthfield you need no worries, it comes with everything you need. I have never had a problem connecting anything when I order from them. As long as you made sure your auto was I entered correctly "make, model, and year"

Q
does it require an after market amp?
john  Feb 09, 2016
5 answers
A
No, but it would be best if you at least had an aftermarket Stereo. I bought a Sony Double-DIN stereo and it was more than enough boost for these.
gerald  Feb 13, 2016
A
Not at all, worked great with my stock system. Eventually if you'd like to upgrade to a head unit that has an internal amplifier these bad boys can handle it and sound even better.
timothy  Feb 12, 2016
A
John, I hooked it up to my existing system - however, I do have the Mach 460 from Ford - which does have 3 amps from the factory. So I would say yes, you should run amps - I also added a powered subwoofer and it really makes the system sound great. Hard to get really great sound without some power (amps) Hope this helps
bert a  Feb 12, 2016
A
No - its a perfect aftermarket replacement. It requires minimal effort to install and sounds great. I was very pleased with the results.
david  Feb 12, 2016

No they do not

Q
My first pair of 1682 came with a plug n play type of adapter so there was no wire cutting. Do these also come with it. It was a white adapter?

I forwarded your question to an Advisor and they responded with the following: We have those adapter harnesses for most vehicles. Just put in your vehicle information into our fit guide online and then add the speakers to your shopping cart. If they are available they will be added automatically. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
