Rockford Fosgate Prime R168X2 speaker

The flush-mount tweeter allows this speaker to fit in more locations and provides a more focused image.

Excellent factory replacement

Whether you're building your first system or replacing some burned-out factory speakers, Rockford Fosgate's Prime Series R168X2 6"x8" speakers offer clean, powerful performance that'll keep you and your friends rockin' as you drive. Plus, Prime speakers are a great way to get Rockford Fosgate sound quality without destroying your bank account.

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 not included — factory grilles are appropriate for most applications.

Product Highlights:

  • 5"x7"/6"x8" 2-way speakers (pair)
  • polypropylene woofer cone with rubber surround
  • 1/2" silk dome tweeter
  • power range: 2-55 watts RMS (110 watts peak power)
  • frequency response: 51-20,000 Hz
  • sensitivity: 87 dB
  • top-mount depth: 2-9/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why replace your car's original 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.

Product Research


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.

Crutchfield Customer Review (What's this?)

I LOVE the sound of these silk domes. They were recommended by the Crutchfield staff, since I ordered four polk db571 but found out they won't fit my front door. I LOVE them. I told my friend about my order and he said "don't bother opening them, just return them, they sound muddy" I'm glad I didn't they sound GREAT. to each his own. clear sound with a warm feeling. not tinny or ear piercing.

Pros: clean warm sound. Not tinny at all. doesn't pierce my ear when loud.

Cons: none yet :)

As usual, qualified by, "for the price...". These things KICK! Very impressed by the substantial upgrade over stock. Installed very easily - highly recommended at any price.

Pros: Price and performance.

Cons: Don't have any idea how to determine life span...

A lot of bang for your buck!

These speakers are perfect for stock replacement, and arent bad if your building your first stereo.

Pros: Great high and decent mid, very loud, great stock replacement.

Cons: Not much bass, mid could have been a bit better.

Great for price

Written By mark, Virginia Beach on Monday, September 29, 2014

Crutchfield Customer Review (What's this?)

As usual another fine product from Rockford Fosgate. Very good quality sound, put them in my 2005 F250 to replace some blown Memphis car audio speakers that were installed in 2007. I had some Sony speakers that were to be installed in another vehicle so I put those in first. They were horrible and sounded very poor. I promptly ordered these and as is usual quick shipping from Crutchfield. I installed them the day I received them and they sound far superior to the Memphis car audio speakers that they replaced.

Pros: Great sound for the price.

Cons: None so far.

OK for price

Crutchfield Customer Review (What's this?)

As title says, OK for price. Easy install. Sound OK. but not much better than stock speakers. The stock Ford speakers actually have a better bass! I was going to change all 4, but left rear ones in for the bass. Good sound other than that.

Pros: Easy install

Cons: Poor bass

Great speaker for the money

The speakers sound just normal. They do sound better than the stock speakers that came with the car. I don't have them hooked up to an amp at the moment. I will write another review after I get them hooked to the amp.

RF Prime R168X2

Written By Joe, Rolla, MO on Saturday, October 05, 2013

Crutchfield Customer Review (What's this?)

I recently sold my old Ford F-150 and replaced it with a Ford Ranger Supercab. I had upgraded the rear speakers in the F-150 with a pair of RF Punch P1683 3-way speakers. I checked and saw they would fit the rear doors of the Ranger, but not the front doors. I gave Crutchfield a call and talked with Mike. He recommended I stick with the RF family to get the best sound match to the P1683's and recommended the RF Prime R168X2. He also made sure I got the proper wiring harnesses adapters for the Prime and Punch speakers to make my installation a breeze. The master sheet provided simple instructions for properly getting into the door panels and replacing all of my speakers. Tremendous sound upgrade over the 13 year old factory speakers breathing new life into the factory head unit. I had initially wanted some 3 way speakers, but I am very pleased with these 2 way speakers. Plenty of high end response for my ears. I am very happy with the speakers and as always very pleased with the level of support and service I received from Crutchfield.

Pros: Great mids and highs. Good base for a small speaker.

Cons: None.

Crutchfield Customer Review (What's this?)

I installed these in the rear of my f150, they were quick and easy to install after disassembling the door XD. i have a 12" rockford fosgate punch p3s installed in my truck, i had a local pro installer give me a quote to install these ( which was absurd $$) who told me these speakers wouldn't sound good with my sub....i took my speakers home installed these and the smaller version of the same speaker in the front and they sound awesome....i would recommend these to anyone on a budget or looking to fix some blown speakers....if you dont have the cash for a phenomenal set with an amp to power them then look no farther these are a great buy for the price... they aren't as crisp as some other speakers out there and they aren't super bright.....but the sound quality for what you pay is astounding!

Pros: greater sound quality from stock

Cons: cant think of any

Great speakers. I bought these to replace my pioneer speakers, and they sound great. Clear treble, and pretty good bass. I would recommend these to anyone looking to replace stock speakers in their car.

Pros: Sound and look great!!

Cons: Nothing

Great Speakers for the Price

Written By Connor, Kaiserslautern, Germany on Saturday, June 01, 2013

Crutchfield Customer Review (What's this?)

Just installed these speakers in both the rear and front of my 2013 Mustang. Although anything other than those stock speakers will probably sound good, these sound Amazing! I'm very happy with my purchase and would recommend these speakers to anyone.
