Better components give you better detail

The Prime R165-S 6-1/2" component speaker system sports stiff mica-injected 6-1/2" 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.

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

With supplied bracket great fit in my 07 tundra. Sound is incredibly clean and huge improvement over stock. Inspired me to install a whole new system with exception of head unit.

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.

The set has good specs. This set has the highest sensitivity, 92 dB, in my budget range. The low end is only 60 Hz but I will add a sub-woofer some day. Rockford has a good rep and, lastly, they will not stand out visually and tempt someone to break in the car.. [ Gary  Nov 10, 2016 ]

to replace the bad factory ones [ justin  Jan 05, 2016 ]
A component system gives you more flexibility to tailor the sound of your environment to your specific tastes. Mounting the mid-bass in a factory door or shelf position and the tweeters up higher on the a-pillar or dash will enable you to create a more immersive and expansive sound-stage. [ James  Dec 28, 2015 ]
Price was best [ Mark  Dec 15, 2015 ]
Recommended by friend that purchased same. [ Jim E.  Dec 14, 2015 ]

They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Jun 04, 2017 ]  Staff
Technically I think so, but that's all your high end / vocals. So you will just have a lot of mid-tones and bass if you leave them out. You should look at getting a 2 or 3 way speaker that fits your rear door. There should be lots. [ Scott  Apr 26, 2017 ]
Sure, but it would be a crime to do so! Plan it out just a bit more, I've never heard of someone regretting extra work for tweeters! [ David  Apr 07, 2017 ]
Jeremiah, I installed my set in a 2002 GMC Seirra Pickup in the front doors. My original setup included separate tweeters, so it wasn't necessary to leave them out. But, I don't see why you couldn't lead them out. You will lose some high end response however. [ David  Apr 07, 2017 ]
Better sound with them. I didn't have a factory spot either, so made one to fit. If you can't find a spot, go without the tweeter [ Jay  Apr 07, 2017 ]
Yes you can. But will only have mid level sound. [ DUSTIN  Apr 07, 2017 ]
Jeremiah, I installed the speakers in 1967 F100 and used the retro housings for them, because there was just one speaker in dash. The speakers sound great so I would say use the tweeters. my opinion Tim [ Tim  Apr 06, 2017 ]
Well I left mine off and kept he factory ones. They say I should have replaced them but I didn't. It does sound a little better but I did the rear speakers also. Even with all the door speakers replaced, there was not a huge improvement so do not expect it. The factory radio, if that is what you have is detuned and it sucks. If you you want better quality plan on replacing the head unit. There is another company called Taco Tunes that makes a tuner and amp that plugs into the factory head unit if that is what you want. I want to give it a try but just haven't had the time to deal with it. [ RICHARD  Apr 05, 2017 ]
I was not happy with the range on these speakers. I do not think they have the capabilities you are looking for. I would suggest going higher end. [ Michael J.  Apr 01, 2017 ]
You can connect them directly, but you take a chance on mismatched power levels and mismatched crossover slopes, as well as the chance that the factory stereo has pre-equalized the sound to the tweeters. It'll work but your'e better off hooking up these speakers as intended. [ Gregory  Mar 20, 2017 ]
I know the stock wiring will work fine, but I don't know about the "connectors". [ Dale  Mar 20, 2017 ]
No there is no crossover supplied. The Prime series is primarily for factory replacement and no other upgrades. They sound good at low wattage, but if you're adding an amplifier I would go with something in The Punch or Power series. Both of which come with a passive crossover. [ Zachary  Dec 09, 2016 ]
They are built in [ Gaspar  Dec 09, 2016 ]
There is no external crossover. Aso far as I know, nothing is built into these speakers either. I had them in my Jeep, running off a Kenwood deck, and it was adequate at best. If you use an amp they'll probably be good. Jeeps have terrible acoustics anyway [ Papa J  Dec 09, 2016 ]
The crossovers are built in. [ Jeffrey  Dec 09, 2016 ]
It is only a capacitor for the tweeter. Not a separate crossover. [ Chad  Dec 09, 2016 ]
The factory door woofers and tweeters are wired in parallel so, if you plan to power the speakers with the stock wattage, you'll need to connect the factory tweeter's input & output leads together in order for the woofer to still get the power & signal. As a result, you will want to use the crossovers provided with the components and run new wire from it's outputs to the separate midbass and tweeters. I hope that helps. My Bio: [ Ryan  Oct 19, 2016 ]  Staff
Thanks for your question. This is for one pair that includes the woofer and tweeter. It would only cover two doors. Hope that helps. [ Kenny  Sep 21, 2016 ]  Staff
I am not 100% sure on this setup, but seems like it should work without any issues. Best of luck!!! [ Randall  Sep 12, 2016 ]
A component system has a separate tweeter and woofer, so you get 4 independant speekers. Where a 3-way has the the tweeter, crossover and woofer built into one unit, so only two assembled speakers will come in the box. [ Zachary  Dec 09, 2016 ]
Alright Tara, not sure about the install, usually the Crutchfield site will tell you what you need for install in your car when you select it. As for the difference between 3-way and component; the major difference is assembly. A component speaker set has and mid range woofer and separate high pass filter, and the high range tweeter. If your powering the speakers with a separate amplifier I 100% recommend the component setup. If you just want beetle than stock speakers I would stick with a normal 3way. Install will be easier with the 3way. [ TANNER G  Aug 05, 2016 ]
As long as your speaker door holes are for the size of speaker you should be fine. Might need to get wire connectors from wires in door and cut the custom fitting on your speakers came with your 300C. Component system and 3 way...3 way has highs, mids and basically your treble, mid-range and bass all in one speaker...component has speakers in the door and then your tweeters as well...I would prefer the 3 way speaker for best sound....hope this helped somewhat, have a good day!!!

This includes 2 Woofers 2 Tweeters, you can see everything that comes in the box on the product page under the details tab. Hope that helps. [ Kenny  Feb 27, 2016 ]  Staff
Thanks for your question. These have a power range: 2-40 watts RMS (80 watts peak power). You'll find this on the main product page overview. [ Kenny  Feb 15, 2016 ]  Staff
No! Foam will never be as durable as Rubber. Now with that said, will the foam outlast the speakers life, or the usefulness of the speaker...probably. If you plan on keeping your car forever, live in very dry hot environments and listen to EDM I'd say go for the rubber. If you listen to talk radio, don't plan on keeping your car for more than 5 years and live next to the beach, foam will be fine. As for sound, that is subjective. Some people have seen UFO's too. [ Matthew  May 28, 2016 ]
Yes I think they are just as durable. I also think the sound better. Hope this helps you out. I have had mine for about two years and I love them. I would choose anything beside Rockford. Good luck [ Clayton  Nov 23, 2015 ]
Not required but can be helpful. Have these in the rear of my Tundra and they sound great mated to an aftermarket head unit. Granted its getting 30 RMS. I would say you'd be fine as long as the head unit is supplying >20 watts RMS. YMMV and hope that helps. [ GREGORY  May 29, 2015 ]
Depends on your head unit. You need to make sure the speakers impedance matches. Also how many watts your stereo has to push them. I didn't need an amplifier and mine sound awesome [ TODD L  May 29, 2015 ]
No, just replace old speakers with these. [ DREW  May 29, 2015 ]
You don't have to but they will sound better if you do [ JONATHAN  May 29, 2015 ]
I have a 1998 dodge dakota I've used these on two jvc units and a kenwood unit they awesome! I am extremely picky about my sound as well and I've had the for about a year now still sound good! [ GUNNER  Sep 15, 2014 ]
My speakers rock [ CHARLES D  Sep 14, 2014 ]
Yes they will. I have an alpine CD receiver and they sounded great!! Especially with an alpine radio because they have a lot of tuning options. [ JONATHAN  Sep 14, 2014 ]
They are good highs. Also get 6x9s for some thump. Country sounds good. Rap not so much [ KARL A  Sep 14, 2014 ]
Hello, I do recommend getting an amp as I installed these without an amp and sure they sound good but you're not using them to their full potential. Also since you have an aftermarket deck they will sound even better with the aftermarket amp. But if you're not going to buy an amp might as well keep the stock speakers since most factory amps only push less then 20 watts also not only will it benefit the speakers it will also benefit the deck.
