Classic components

One thing's for sure — our customers love Infinity's Reference Series speakers. Year after year, car after car, options like this Reference Series REF-6530cx 6-1/2" component speaker system remain a popular choice for replacing factory speakers because of their competitive pricing and superb sound.

Edge-driven dome tweeters

With this component system, you'll gain exceptional clarity and imaging, thanks to separate 3/4" edge-driven textile dome tweeters that subdue any harshness in the high-frequency range. Infinity includes external crossovers that give you push-button tweeter attenuation for a "brightness" quick fix.

Bigger woofers

The Reference Series polypropylene woofer with its durable hi-roll rubber surround ensures you'll enjoy powerful sound every mile you drive. Its oversized cone moves more air than other speakers of similar size, adding plenty of punch to the speaker's impressive performance.

Bring on the power

You can power these speakers with up to 90 watts of RMS power — they'll work well with an external amplifier, but they're also a good match for a factory radio or aftermarket stereo. Plus, these 3-ohm speakers combine with the speaker wire in your vehicle so your car stereo sees actual 4-ohm impedance, so you get a little more volume out of your system.

Product Highlights:

  • component speaker system includes 2 woofers, 2 tweeters, and 2 crossovers
  • 6-1/2" Plus One+ polypropylene woofer with hi-roll rubber surround
  • adapter rings included for various speaker openings
  • 3/4" edge-driven textile dome tweeter
  • Starfish™ mounting brackets for easier tweeter installation in factory locations
  • True Four Ohm Impedance technology
    • speaker's 3-ohm impedance combines with speaker wire impedance for a 4-ohm load
    • compatible with virtually all factory or aftermarket car stereos
  • tweeter adjustment circuits (0, +3 dB)
  • handles up to 90 watts RMS (270 watts peak power)
  • frequency response: 53-21,000 Hz
  • sensitivity: 93 dB
  • woofer mounting depth: 2-1/16"
  • grilles included
  • warranty: 1 year
  • Our 60-day money-back guarantee

What's in the Box:

  • 2 Woofers
  • 2 Tweeters (each has attached 6" speaker leads)
  • 2 Crossovers
  • 2 Woofer grilles
  • 2 Grille frames
  • 2 Woofer mounting rings
  • 2 Tweeter flush-mount housings
  • 2 Threaded flush-mount adapters
  • 2 Plastic locking nuts
  • 2 Tweeter surface-mount housings
  • 2 Starfish tweeter mounts
  • Eight 1-3/8" Screws
  • Sixteen 1-1/8" Screws

  • Six 5/8" Flat head screws
  • 2 Washers
  • 2 Nuts

  • Instruction manual

Great all around speaker. Will probably give 5 stars once I amp them up and throw in the tweeters. Tested the tweeters out but havent flush mounted yet, but I'm sure it'll be a breeze with the detailed instructions they sent.

Very happy with the sound, excellent improvement over the stock GM speakers. Shopping was s breeze on-line.

Pros: Far superior audio at all frequencies, no complaints.

Crutchfield Customer Review (What's this?)

Bought these to replace my older Polk Audio speakers. They are paired with the Kenwood DNX691HD receiver and powered by an Alpine (MRX-V70) amp. Installed these in my 2002 Chevy Tahoe and love the clean crisp sound at all volume levels. The highs and mids are much better than the previous speakers. These were installed in the front doors and the Infinity Reference REF-6532EX 6-1/2" 2-way Speakers were installed in the rear doors. Absolutely love these speakers.

Pros: Clear and Crisp Sound

Cons: None

Event for the price. Much better clarity then factory speakers. Powering with 100 watt amp. Can get very loud and clear.

Pros: Good sound

Cons: Adapters has to be modified but easy to do.

Great speakers. Consider buying your own screws though.

Crutchfield Customer Review (What's this?)

Speakers sound great! I'm not a orofessional installer so I'm only rating the speakers themselves but they come with super long screws that may be too much for the doors you are putting them in. Consider getting your own mounting screws.

2006 Cadillac Escalade
Crutchfield Customer Review (What's this?)

Picked these up on a great sale at an excellent price. This is my first set of Infinity reference speakers. I replaced the front factory Bose speakers in my 06 Cadillac Escalade and they sound great. Using the factory head unit and amp. Also added a sub to it. What a difference. Now I have to replace the rear speakers too. These sound so good over the factory rears. You can really hear the difference.

Pros: Great sounding set of speakers. The highs are awesome and clear at any volume

Cons: None so far!

Great set of component speakers

Michael from Erie, PA on 12/18/2018

2001 Mitsubishi Eclipse Spyder
Crutchfield Customer Review (What's this?)

I got these on a Black Friday special at an excellent price. These are my second set of Infinity reference. Just like before, they are nice quality all around both in looks and in sound. Still wish they had a little more power, but that is more an issue with the amp/setup than with these speakers. Just a shame they get covered up inside the doors.

Pros: nice quality, good looking and sounding set of speakers. Great Black Friday price too!

Installed in my 2018 Tundra ... stock headunit but run thru a Rockford Fosgate R600x5 amp ... installed the tweeters in the sail panels ... great sound and clarity, esp the mids and highs but they do pump out the bass pretty well too ... yes I would definitely buy again

Crutchfield Customer Review (What's this?)

Replaced all four stock speakers in my GMC Sierra 2500. Was given all hardware for free to make this an easy seamless install. I still have the stock look with great sound quality. These infinity speakers give me the clean high quality sound I was hoping for.

Pros: Easy install with given hardware and instructions.

Cons: No negative things to report.

Better than expected

Crutchfield customer from Mc Gregor, TX on 8/20/2018

2000 Toyota Land Cruiser
Crutchfield Customer Review (What's this?)

After running Infinity's in several different vehicles, these component speakers exceeded my expectations. Would have gotten five stars if it had more low range.

Pros: Great Mid range quality and clarity

Cons: Not quite as much low end as expected

How a novice puts together a quality system for a Jeep Wrangler

Dave from Downey, CA on 7/23/2018

2011 Jeep Wrangler Unlimited
Crutchfield Customer Review (What's this?)

Installed these speakers as replacements for my factory OEM speakers in the dash panel. Tweeters were included. Originally I was going to use what most people are using in their Jeeps for replacements......Kickers. After speaking with Mac, he put me on track with a much better set of speakers. Loving the change. Can't wait for the next phase of my upgrade. Mac set me up with a complete system, made sure I had everything I need to do a clean, professional installation. His advice was worth a million to me. It cost me nothing. I'm not a professional, and would have probably copied someone else's system from a Jeep Forum. Glad I didn't. Mac put together a system for me based on my vehicle, and my music preferences. I'd have never been able to do that. What I learned from Mac is that just because something is touted as the "latest/greatest thing", doesn't mean it's going to work well with all of your other equipment. Like most electronics, they need to play well together. The other invaluable thing I got was step by step directions for my particular vehicle and system. Not generic directions that have no semblance to my application. If you're a non-pro like myself, give Mac a call. He'll hook you up.

Pros: -Crazy fast shipping -Top quality parts -Great customer service and response time.

2008 Chevrolet Avalanche
Crutchfield Customer Review (What's this?)

Wow, this is a significant improvement over my factory speakers, which were the Bose premium sound system speakers. Excellent base and clear mid and highs.

Pros: Mounting brackets and wiring harnesses sent by Crutchfield made installatiin much easier.

Cons: No installation instructions included anywhere and the generic instructions sent by Crutchfield are worthless. At least their phone support is great.

Great overall speaker

Pros: nice highs and and good bass

Cons: none

Clean and refined sound, lacking bass

Elijah from Hot Springs National Park, AR on 7/4/2018

2007 Hummer H3
Crutchfield Customer Review (What's this?)

I expected a little more from these speakers. My factory speakers had much lower bass response, but these are much more crisp with less muddled sound. As these were my first speakers to ever put in my car, installation was hard. I did have to call Infinity customer support and they weren't very helpful. I had asked them which wire was the input that was supposed to go to the crossover and they couldn't tell me. They did tell me it was one (of the four) from the mid range woofer but couldn't specify which one. At that point I said thank you and started trying to figure things out myself. I ended up attaching the wiring harness included with my order and running wire connections from that to the cross over then from the crossover back to the mid range and tweeters. This ended up working, but goodness did it take a while to figure out. I couldn't find anything on the internet about it. For the tweeters on this, none of the included adapters fit. I ordered 2 back straps and didn't use them. I shaved down part of the factory enclosure to allow the tweeter to fit which makes it look factory. The mid range speaker install was much easier. All in all it was a great learning experience and I'll be more prepared for my next install.

Pros: Got them on sale, big upgrade from factory speakers, loud

Cons: Installation, lack of bass

amazing sound in 2015 Jeep JK, these plus Pioneer double din bluetooth receiver, Alpine 5 ch 100 w x4 500w x1 amp, Alpine sub. previously upgraded roll bar speakers. all pretty straight forward install with Crutchfield instructions, harnesses, etc. The 9 wire speaker wire is a great help compared to the old days! plan to give yourself lots of time and room to do this install

Pros: awesome sound in a open top jeep

Product Research



Plus One+ Woofer Cones: Each speaker uses a larger cone than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and an increase in efficiency.

Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.

Mounting: Without an adapter, the 6530cx woofers fit standard 6-3/4" applications. Given their required cutout, they will also fit 6-1/2" applications without an adapter, but new screw holes must be drilled. Using the included adapter brackets they can be mounted in a wide variety of 6-1/2" and 6-3/4" applications, without any modification.


Material: Each tweeter features a 3/4" edge-driven textile dome for smooth, accurate highs.

Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

  • I-Mount: The tweeters can be surface- or flush-mounted with Infinity's innovative I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount housing and plastic locking nut. Once a cutout is made, the tweeter is installed in the flush-mount adapter, then into the flush mount housing and inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Bottom Mount: Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Surface Mount: Once the Starfish bracket is trimmed, it is screwed to the top of the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount: There are two sets of tabs to flush mount the tweeter in the Starfish bracket, yielding different mounting dimensions. The upper tabs mount the tweeter completely below the opening and are glued in place. The lower mounting tabs are screwed in place and result in a mounting height just under a half inch. Once the bracket is mounted, the tweeter is inserted into the bracket and locked into place.

Cutout Diameter N/A 1.581" N/A N/A 1.504" 1.257"


Selectable Tweeter Output Level: Each 2-way crossover allows you to select the tweeter output level according to system requirements and personal preference; the tweeter level can be set to +3 dB or 0 dB.

Connections: The crossover inputs and outputs are screw terminals; they will accommodate bare wire or spade connectors up to 0.3" wide. There are four mounting holes in each crossover.


  • Width: 4"
  • Height: 1-1/8"
  • Depth: 3-1/4" (plus wire)


High-Output Design: The 3Ω voice coil design compensates for the high in-line resistance of small gauge factory wiring, extracting more power from factory (or aftermarket) receivers. This results in clearer, richer sound for the listener.

Good deal [ John  Jan 12, 2019 ]
If was in the market to upgrade my front speakers in my 91 Camaro. I was worried about it complimenting my current system. (Pioneer head unit, JL Amps and subs) I was wanting to buy JL audio to keep my equipment the same brand. The Infinity Reference just sounds more crisp and clear. (C2-650) The sensitivity is higher at 93db and the higher wattage is a plus too. I love my JL Audio but I have to buy what sounds best and is in my price range! PS-Drummer was awesome advisor! [ Christopher  Jan 02, 2019 ]

Looking for good component speaker system at good price. These were 50% off. [ JOHN H  Nov 24, 2018 ]
My factory speakers aren't putting out the sound I need in my truck and I had the Infinity reference speakers in my old truck so I thought why not try them again. I also bought a set of two way Infinity's for the rear doors. I hate all new music all I listen to is 60-70 classic rock, blues, and a lot of dead guy's. These speakers will get the sound I need on the CHEAP! [ GLEN  Nov 23, 2018 ]
I like the specs and it is a good brand! [ Donald  Nov 17, 2018 ]
These are an upgrade to my daughter's car. I chose this component set for the front doors and a matching 2-way set for the rear doors. The impedance and sensitivity should provide a good match to the factory head. [ Jeffrey  Oct 18, 2018 ]
Past experience with Infinity component speakers were positive. Sound quality has been very satisfying, price point is a bonus. [ Randy56  Aug 13, 2018 ]
Kappa's with the larger magnet would not fit the back doors (and clear widow actuator) of my 4door Silverado. These just' clear and compliment the system nicely. [ MARVIN  Jul 13, 2018 ]
came recommended [ MANDEEP  Jun 29, 2018 ]
Because of the low impedance technology. If it can save me from buying an amplifier right now, that was the selling point [ Elijah  Jun 19, 2018 ]
