Rockford Fosgate Prime R1675-S

Excellent factory replacement

Whether you're building your first system or replacing some burned-out factory speakers, Rockford Fosgate's Prime 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

The Prime R1675-S component speaker system sports stiff mica-injected 6-3/4" polypropylene woofers that deliver strong drums and bass, along with clean reproduction of the midrange frequencies. The separate Mylar tweeters add the excitement of strong high-frequency response to your music without a trace of harshness. Built-in crossover networks divide the frequencies going to each driver, so all your music plays faithfully. Grilles are included.

Note: The oversized terminals on these speakers won't connect to a Crutchfield wiring harness. A free 10-pack of female quick slides that you can splice onto our harness will be included with your speaker purchase.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Product Highlights:

  • component speaker system includes 2 woofers, 2 tweeters, and 2 woofer grilles
  • 6-3/4" mica-injected polypropylene woofer cone with foam surround
  • 1/2" Mylar balanced dome tweeter
  • power range: 2-40 watts RMS (80 watts peak power)
  • frequency response: 55-20,000 Hz
  • sensitivity: 92 dB
  • top-mount depth: 2-3/16"
  • grilles included
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Installed in front doors of 2014 Elantra sedan. Powered by Fosgate R600X5 amp. Mid-Bass is very good, highs are crisp.

Pros: Sound quality is great. Good value

Cons: Top mount only and tension ring "keepers" to hold the tweeters in place limit install options- may have to get creative if space is limited.

Speakers sound great, still have them attached to the factory head unit and they are a huge improvement over factory speakers, the tweeters are not easy to install in the 2015 kia forte because of the confined area but definitely some good speakers

Pros: Sound great

Crutchfield Customer Review (What's this?)

I put these in my 07' Tacoma in the front doors behind a Kenwood Excelon KDC-X798. along with Rockford Fosgate Prime R1675X2 in the rear doors. Sound is GREAT!! I used the Crutchfield supplied mounting brackets that I had to modify a bit to mount the speakers. One in the brackets mounting to the door was easy. Your not going to get bone jarring base out of these but they do have nice bass and great sound. Looking at getting another set to put in my 02' crew Chevy.

Replaced my factory speakers in a new 2014 Ford Focus SE 6-speaker setup. Had these professionally installed with baffles on the woofers, keeping the factory stereo. Significant upgrade over factory speakers. These speakers exceeded my expectations.

Pros: Cost, brand reputation.

Cons: none

Great sounding speakers. You cannot beat the price for these incredible highs and mids. Bass is exactly what you'd expect for 6.5's. Would recommend to anyone. After I installed them the guy who helped me immediately asked so how much did you pay for these? I imagine he'll have them soon too.

Pros: Sound, Price and Quality of Materials

Cons: None

Need to have correct sizing

Written by: Codaleks from Howard KS on June 16, 2014

Sounds decent, bought these for my 11 tahoe front doors and oem tweeter location, but someone at Crutchfield messed up with information, info page on page lists tweeter at 1/2", when actual measurement is 1 1/2in, with mount it's 1 7/8in

Pros: Sound

Cons: Tweeter size

Crutchfield response on June 18, 2014 The listed tweeter size is the manufacturer's listing for the diameter of the actual tweeter dome inside the plastic housing. The real mounting dimensions are listed on the Details tab of the speaker's webpage. In this case it is a whopping 1.83" cutout for flush mounting, 2.125" flush mount frame diameter, 1.815" surface mount frame diameter. Installing tweeters is almost always a custom job. If these don't work out, don't forget about our 60-day money-back guarantee.

Written by: Cecil27455 from GSO NC on February 15, 2014

I blew the front driver side speaker in my wife's Acura TL. I went to a local place and they showed me these. I couldn't be happier. My wife heard them and had to get the rears replaced. Acura's have an issues with the speakers in 2009 these are a great replacement.

Pros: Everything is a pro good highs and good lows

Cons: None I can think of!

Good Clarity

2001 Dodge Ram
Crutchfield Customer Review (What's this?)

I bought these speakers to replace my factory speakers in my 01 Ram Pickup and was very happy with the clarity of the speakers. I had an aftermarket clarion head unit to begin with so I could easily compare the sound from factory to then Rockford speakers after the install and it was worth every penny. I'll be the first to admit the head unit is arguably the biggest dictator in sound clarity but even with a very modest head unit, these speakers perform well above their price tag. Overall, very happy with purchase and would recommend to anyone!

Great component set for the money!

Written by: Rob from Long Island, NY on July 5, 2013

Crutchfield Customer Review (What's this?)

I was impressed by these component speakers and especially for their price! Better sound than a pair that I bought for a similar setup costing almost twice as much.. I am running them off a Blaupunkt head unit using its built-in amp. I bought this set for the rear as a test and will definitely be buying another set (though may have to get a smaller diameter) for the fronts.

Pros: GREAT price, includes all wiring and multi- tweeter mounting options.

Cons: None

1996 Toyota 4Runner
Crutchfield Customer Review (What's this?)

I blew my budget getting a much nicer head unit than I intended, so had to bargin shop for my speakers. I am very impressed with the product! My 1996 4runner comes with 5 1/2 " door speakers with seperate tweeters mounted atop the door. I was excited to know that these were A) direct fit and B) 6 3/4". I expected better base from these compared to stock but they are only marginally better. Tweeters are so close to mounting perfectly without any modifications. But a few minutes of altering and they fit great. I would buy these again for the price as the overall sound quality is vastly superior to stock.

Pros: Price, sound quality, and ease of install.

Cons: None.

Product Research


Mica Injected Polypropylene Woofers: The woofer cones are mica injected polypropylene. This material is light weight and rigid for decreased distortion and improved bass response.

Tweeter: The 1/2" Mylar tweeters are a balanced dome design. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter. Out of the box, the tweeters are mounted in the flush mount housings. An angled surface mount housing is also included, and the back of the the flush mount housing and the top of the angled surface mount housing are combined to make the (non-angled) surface mount housing. Once mounted, the tweeters swivel so you can direct them toward the listening positions.

Tweeter Dimensions:

  Frame Diameter Frame Width Frame Depth Cutout Diameter Mounting Height Mounting Depth
Flush Mount 2.125" N/A N/A 1.83" 0.34" 0.752"
Surface Mount 1.815" N/A N/A N/A 1.1" 0.66" (Screw Depth)
Angled Surface Mount N/A 1.815" 1.845" N/A 1.661" 0.59" (Screw Depth)

Crossovers: A 6 dB/octave high-pass crossover is integrated into the case of each tweeter. The woofers have two spades on each terminal; the wire from the tweeter, as well as the wire from the source are connected there.
