I’ve completed this mod with help from this thread and will relate that 996/911 6x40 amps are available in both coupe and cabrio versions. I’ve tried both and will report the cabrio version is preferable. In fact it’s amazing, as the original 4x40 amp must have been a poor spec, as with the cabrio 6x40 my original door woofers have come alive, performing much better with more volume than previously. 6x40 amp I have has 323 in part number.

My indy has PWIS but says can only update VIN and can't reset mileage. Is there a solution he hasn't found?

I had the usual reservoir leak and messed around trying new cap, and doing something I can't recall with the pressure release valve. The real solution as stated more than once above is a new reservoir from Porsche. Understand that due to German regulation every bit of plastic on these cars is biodegradable and at 20 years it's simply time for a new part. Just regular maintenance. Biodegradable ... it's the reason your radiator grilles on your base model are now gray. They were originally black. S grilles came painted titanium silver, but still there is a black plastic ring in the center radiator opening that biodegrades to gray as well.

How about a 2022 thread to ask for sources for this hard to find fluid? Leads welcome and thanks in advance. BTW ... isn't this usually described as a transmission from Audi? Is there an Audi part number for this fluid? Audi sources?

Your door speakers are woofers, so fading them either front or rear is meaningless.

I recommend the unit with 323 in part number. Not sure about the other one, but do know 996 6X40 amps come in coupe and cabrio versions and you want a cabrio version, which 323 is. You'll be pleasantly surprised by improved door speaker (woofer) performance with this amp. There are older posts in this forum that will describe the wiring modifications required. Note that this is just amp-out wiring. The amp-in wiring from radio is already all there, no changes required. See

I believe you're misinformed (actually misinforming) on this. As you surely know, the major German manufacturers all publish motor oil specifications which oil manufacturers must prove they meet. It's a formal process. Of course ACEA specifications are included. The fact is, any motor oil that meets the Porsche spec will be a full synthetic and meet a viscosity requirement. I once researched Mobil 1 products and learned that the cold pour points of 0W, 5W, and 10W versions were exactly the same. That's all that's of much importance regarding the W number in a viscosity specification, that is cold start ability. I'd not spend a nanosecond wondering which I should choose. The warmed up running number provides few realistic choices as regards 986 and these of course will be either 30, 40, or 50. (BMW sometimes likes 60) Again, if the product meets A40 the viscosity will be usable. 986 engines are a little older obviously, but in 2021 Toyota for some models specifies a 0W-16 motor oil and you can take to the bank it isn't going to fail in Death Valley. Neither they nor any other other manufacturer are blatantly or otherwise attempting to have your motor wear out prematurely--that's grassy knoll conspiracy mongering devoid of intelligence or interest. Experience indicates that it is typical self promotion felt needed by mechanics to dismiss factory engineering, in this case motor oil specifications. Typically, as again here, without technical supporting detail. I suspect it's especially ego satisfying and impressive to novices to recommend exotic things like Joe Gibbs oil. My response is if any of you are petroleum engineers, you'd have a better job. To blame bean counters or marketers is again typical nonsense. PS: ok, this is Porsche and we can all have lots of fun. If yours is a track day only vehicle, have fun using an exotic oil ... in fact have fun using it in a daily driver. The statement that A40 is all you need to know is accurate for most driving conditions and probably Porsche has set you free to do what you want for racing, as it doesn't accept responsibility for that in any event. PPS: these comments strictly about motor oil, other contributions on mechanical issues long appreciated.

In mid 1990s new regulations were passed in Germany requiring auto parts be biodegradable. Wiring then, is performing as designed. First generation after a new requirement is seldom perfect; next and later generation cars always have better solutions. Many now have CAN Bus electrical systems which significantly reduce the amount of wiring required. Complaining about 20+ year old used cars is pretty silly anyway. They are what they are.

I think once you find "Porsche A40" on the bottle your search can be over. Liqui Moly appeals to me a little more than Mobil, but both meet the standard. Viscosity is irrelevant.

Here's why it drones. Unlike most cars that have their exhaust systems attached by hangers mounted to the under body, the Boxster exhaust system is mounted to the transmission ... which is mounted to the engine. The engine and transmission mounts are "tuned" to the weight of the engine/transmission/muffler package and when you reduce that weight by fitting a lighter (they are always lighter because they are cheaper) aftermarket exhaust, you have made the system out of tune and the drone is the result. There are actually aftermarket systems that do weigh the required amount.

FYI 1999-2005 Porsche 996 911 Cabriolet Amplifier Amp 6x40 99664532300 M490 Haes WWW.EBAY.COM Porsche 996 Convertible Cabriolet radio stereo amplifier. HAES 6x40. In excellent condition.

No, recall that Porsche sells as an option rear shelf speakers that would perform the function of fader rear. There is of course no directional presence for low frequencies ... and 2 of the four amp outputs are post crossover separation of low frequencies for the door woofers. It makes no sense to control them as fader rear and imho little sense to convert them to full range speakers ... again the rear shelf speakers are a better solution. See Suncoast Porsche for the kit. Search here will reveal a “pin out for 6x40” thread that will detail how to get rear outputs for full range rear shelf speakers. FWIW there are unused direct to speaker outputs on the Oe radio and those can be used to connect rear speakers as well. Nicer obviously to power them from auxiliary amp. its pretty easy to find a 6x40 amp from a 996/911 on eBay. They come in both coupe and cabrio versions and I’d recommend the cabrio version. Note that the wiring between radio and amp already includes rear speaker wires, so the only work is to accomplish amp to rear speaker wiring. As an aside, I’d venture the 4x40 circuit for the door woofers is limited ... when I installed the 6x40 amp, the door woofers really came alive ... it’s all around a better amp. Finally, note also that option 490 dash speakers are mid range plus tweeter, the crossover being at the speaker. And 6x40 means 2 dash, 2 rear, and 2 door woofers.

Yes. The "brown plug" is used for the direct to speaker option. Not needed if going through the aux amp.
