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.

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.

Replaced factory speakers in a 2003 Toyota Corolla. Great component system for the price. I could not be more satisfied from the easy install to the fantastic sound that these speakers produce. Great highs from the tweeters and booming lows from the bass.

Features

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.

1 question already asked

Eh, ok, running from stock 80 watt deck they play but no bass not bad quality their alright [ RONALD  May 05, 2016 ]
There is a built in crossover on the speaker itself. I have a pair in the front doors and they sound awesome! Clear highs and low lows with great mid range too. [ Eric  May 05, 2016 ]
It uses a high pass filter in place of an actual crossover. In my vehicle, they sound fantastic at low and mid volumes. At high volumes they're too bright and tire my ears. I have the same head unit with some jbl's in my other vehicle and I can listen at high volume all day. The "low" end is very good and would be better with some more juice. I'm putting in 20w rms. [ Lee  May 04, 2016 ]
Frank, I bought these speakers long ago enough that I don't remember. The car I put them in is a 2014 Ford Focus, which already had woofers and tweeters (front doors only) in separate locations, so I assume there was already a crossover in the car. I can't be sure. I also don't remember buying a separate crossover. Lastly, I figured I would screw the whole deal up so I had them installed at a car stereo jawn. [ John  May 04, 2016 ]
They worked fine for me yeah. [ Brady w.  May 04, 2016 ]
