A vintage fit

Some cars make it tough to replace your speakers, but RetroSound designed the RetroMod® Series R-463N 4"x6" speakers to fit in just about any vehicle. These speakers use a compact, powerful neodymium magnet structure to keep mounting depth to an amazing 1.35 inches, while still allowing these speakers to handle plenty of power — up to 80 watts RMS. They'll deliver strong performance powered by a car stereo or an outboard amplifier.

RetroSound builds each speaker around a low-carbon, black steel basket, using a polypropylene woofer cone, a Santoprene™ rubber surround, and a Mylar tweeter. Translation? These speakers will stand the test of time in your vehicle, shrugging off damage from moisture or temperature extremes. Whether you're customizing an older vehicle or just looking for some nice replacements, these RetroSound speakers will fit the bill.

Product Highlights:

  • 4"x6" 2-way speakers (pair)
  • polypropylene woofer cone with Santoprene surround

Retrosound R-463N

Written By LarryM, California on Wednesday, November 18, 2015

Crutchfield Customer Review (What's this?)

I needed replacement speakers for the badly deteriorated, original speakers in my 1985 BMW 635CSi. Maintaining a completely stock appearance was very important to me, which I knew would limit my choices. My car also retains its original Alpine AM/FM/Cassette unit and I only use the tuner section, so audiophile-level performance was not really a priority. I selected these speakers mainly because they were the only ones I could find that fit in the stock locations (front kick panels and rear deck pods), without having to make major modifications to the interior. The tweeter on these speakers do protrude about 1/4" but I was able to use my original, flat grilles in the fronts by trimming the carpeting around the speakers so that they mount directly to the car's metal structure rather than on top of the carpeting. The grilles mount on top of the carpeting; since my carpeting is approx. 1/4" thick, I have enough clearance for the tweeters behind the flat grilles. I also used 1/4" thick plastic spacers on each mounting screw between the grilles and speaker frames, in order to prevent the grilles from cracking when being tightened down. The rear speakers were essentially direct "bolt-ins" in my stock speaker pods. I'd rate the performance of these speakers acceptable for casual radio listening only. Don't expect a "warm" sound or deep bass; keep your expectations within reason for speakers of this type given their design limitations in favor of better fit in tight locations.

Pros: -Compact design; good choice for fitment in locations with limited depth, where audiophile performance is NOT a priority. -Choice of materials (polypropylene woofer w/ santoprene surround) means they might last longer than original paper-coned speakers with foam surrounds. -Come supplied with tasteful, attractive grilles.

Cons: -Overall design favoring ease of fitment in tight locations (small magnets/voice coils, etc.) seriously compromises performance. -Elemental build quality doesn't seem up to par with other speakers in this price range. The stamped frames especially seem rather cheaply made. -OK for casual radio listening of classical, jazz, news/talk; forget them if impressing your friends with high-volume rock is your intended usage.

Sound better than expected, but didn't fit.

Crutchfield Customer Review (What's this?)

They sound about as good as advertised; don't buy these expecting anything other than what they are.

Pros: Sound better than I expected, given the super-thin and small form factor.

Cons: Despite Crutchfield's insistence that they'll fit in my 1998 GMC Sonoma, they did not fit at all. I had to wire them in and get really creative with two-sided tape in order to get the dashboard grille to fit once they were wired in.

Fits front door cards on Porsche 944

Written By Jeremy C, California on Friday, June 12, 2015

Crutchfield Customer Review (What's this?)

These shallow depth speakers are exactly what I needed to fit the doors on my '86 944. Crutchfield does not list them as compatible but they will work just fine, with a couple of caveats. The depth of the magnet is short enough that they clear the window regulators with no issue, and with some room to spare. If you use the included Retrosound speaker grilles (which are incidentally dead-ringers for the late style '88-'89 factory 4-speaker type grilles in terms of appearance), these speakers are direct-fit for the car and there are no modifications required whatsoever. If you want to use the original factory speaker grilles, you'll either need to buy or make a spacer to fit on top of the speaker cage, OR you can move the factory plastic speaker mounting bushes to the top of the speaker cage: this will result in a slight gap around the edges of the factory grille vs. the door panel, but it's not really noticeable unless you're looking for it. Compared to my blown-out factory original Blaupunkt speakers these are great, but it is important to remember that these are a fairly basic replacement 4x6 with a small magnet, so it may be wise to temper your expectations. For my admittedly basic uses - just something to make pleasant enough noises while commuting or touring, they are more than adequate. I paired these speakers with a pair of Alpine SPS-406 speakers in the rear seat side panels, and a Nakamichi NA350iBTR head unit with no external amp - it's a better system than stock.

Pros: I am glad that these exist, and am extra glad that they include a grille almost indistinguishable from a factory Porsche part, albeit from a slightly later model than my car.

Cons: These are not anything other than what they are, so keep expectations in check.

The magnet fell off...

Written By David, Alaska on Monday, October 07, 2013

First things first. Crutchfield is a fantastic company, I've made many, many purchases through them over the years. Thank you Crutchfield.

Now on to the review of these speakers.

The magnet fell off the back of the speaker!

Yes, that is right, I installed one speaker, turned on my head unit, turned up the volume a bit, faded over to the left and it all of a sudden started making a terrible, low volume noise.

I pulled the speaker out, and sure enough, the magnet fell off the back of the speaker!

I would NEVER buy another product from retrosound - not until they figure out how to make products that is.

I will continue to buy from Crutchfield.

Pros: Not one single pro about these speakers... nothing... same price as real speakers, worst possible quality.

Cons: None - they were absolutely the worst product I have ever purchased. I have received more durable and reliable items as toys in fast food kids meals!

They fit!

Crutchfield Customer Review (What's this?)

It was very hard to find speakers that would fit my 1986 Porsche 944 and clear the electric windows. While these speakers don't have the best sound, they are certainly more than adequate.

Pros: Very small compact speakers.

Cons: Average sound quality. Very small magnets and plastic cones.

PERFECT for Corrados

Written By Victor, Riverside on Monday, December 10, 2012

For you Corrado owners looking to replace the rear 4" x 6" speakers, well this is the speaker to have. I have a 93 Corrado and they replaced the factory speaker perfectly. No modifications needed; just remove, replace and install. The plus is that it came with free wire harnesses that allows you to connect directly to OEM vehicle connector. It was just unusual that the harnesses were sent separately. Believe it or not I received the speakers within two days while the harnesses took five days. So don't plan on any installations unless you don't care to use the harnesses.

The quality is good and it's amazing how compact they are; it looks like your not getting enough for your money :D

Pros: Compact

Cons: Not much to say other than there could be a little more base coming out of them. But other than that they sound very good. I would recommend them.

Perfect Fit

Written By TG, Washington, MO on Wednesday, September 05, 2012

Crutchfield Customer Review (What's this?)

These were bought to replace the original speakers from a 1986 Porsche 911. They are a perfect drop-in fit. I was even able to use the original mounting hardware from the Alpine speakers. Because of the very shallow mounting depth these were the only ones that could fit and they do fit perfectly. The sound is great considering they are only a shallow 4x6 speaker. The rep at Crutchfield suggested these speakers and he was absolutely correct. Highly recommended for this situation.

Pros: Fit. Sound.

Cons: none

Good speakers

Written By Wild Bill, Spring Lake, NC on Wednesday, January 18, 2012

Crutchfield Customer Review (What's this?)

Nice speakers, way better than stock. These fit into my Porsche 911 (993) with no modification needed.

Pros: Sounds good.

Cons: Not enough base, although that's not a fault of the speaker.

Product Research


Woofer: The speakers feature poly cone woofers with Santoprene surrounds.

Tweeters: The tweeters are low profile Mylar domes.

Neodymium Magnets: The N series speakers feature neodymium magnets. Because neodymium produces a much stronger magnetic field than ferrite (of the same size), the magnet size and mounting depth are substantially reduced.
