The ends Pioneer and Clarion use and the Knu cables you are using, unless damaged, are not the problems.
I am switching out to vampire wires to try and reduce some noise that I have.
Any suggestions?

sounds like you should cryo cool your wires. superconductor > standard rca cabling. I can get you access to LN2 or LHe if needed.
Can you explain this a bit more? lol

now we're talking! we should also run our amps and speakers at cryo temps- just be careful of the containment pressure from the liquid boil off-

imagine the power if our amps were stable at .000000008 ohms!

I actually REALLY like the removable RCA harness. It makes installing the deck much easier. I don't have to hold the deck/dash piece in one hand while connecting RCAs with the other hand. With the harness I just connect all the RCAs up, run the harness in to the dash area and then plug it in. Done.

I wish all audio companies used this kind of modular design. Like Alpine/JL/etc do for their amplifiers.

Unnecessarily large barrel connectors provide no tangible benefit. Much less audible. They may look pretty but you're paying for pretty... in some regards I'm all for this. But not for an RCA jack that's buried in the dash...


And, given this is DIY site, to the folks complaining about the connectors, why not do like Jorge did and make your own? Cut the ends off the harness, solder up your own connectors and rock it. Problem solved. You can use whatever $5 boutique barrel jack you want and gain all the SQ you feel is lost with a standard RCA jack.
Erin, first of all, thanks for all your product reviews. I find them very helpful and educational. Much respect for you. :)

It occurred to me that while other physically larger Alpine and JL amplifiers have standard speaker terminals, perhaps they used a high-current modular connector on the smaller PDX and HD amps because usual speaker terminals won't fit. I agree that a multi-pin connector makes installation easier on these amps. A friend recently installed a JL HD600.4 amp under the driver's seat and the multi-pin connector saved his spine from aching too much. :)

With regards to the P99 RCA harness, the multi-pin connector is (for me) a possible weak point. While it does make installation easier, it is still a connector that may loosen-up and could gather corrosion over time. In two of my friend's cars, simply jiggling a fully-plugged-in connector sideways a tiny bit (a fraction of a millimeter) is enough to introduce noise in one or two channels. Personally, I feel the need to ensure the integrity of low-level signals coming from the head unit. With a non-detachable RCA harness factory-soldered to the PCB, there is one less thing to worry about. :)

Happy Holidays! :)

RCA harness look pretty decent to me, no issues with them. However I have one other complaint regarding the P99. The removable front and the damn connector. The display have blackened out, buttons not responding etc. Cleaned it with some ethanol a month back, but now it's the same issue again. I don't even remove the front or insert any CDs so it's a mystery how the connector somehow got... dirty lol. If you poke the front slightly up and down it works again so I know that's the issue. Too bad the warranty time has passed... =/

The JL XDs use standard terminals and they're smaller than the HDs.

IF anything I think they should have made the P99's harness longer by like a foot. I can think of 20 better places to put the RCA junction Biddle that isn't in the tight space right behind the head unit. And instead of making the plug in a traditional high quality way I would have redesigned them for a car audio specific application. Make them as small and thin as possible, and put an extra long boot on them so they cover the RCA cables plug that you are using as well.

Get the funds for that budget by saving on the worthless copper finish.

Are you sure it's not a full copper chassis? I'd think the copper chassis would be more effective now that in the 90s with how many computers and high voltage lines that are in cars now.

Not sure, but if anything it would have to be some type of allow since cooper is too soft. From what I understand though it doesn't have to be copper, if it did then they would all have to bring it. Don''t think all companies would put out a product that was susceptible to that. Some don't have metal cages period, they use plastic with metalized paint on the interior. Dunno if you remember the problem with the first bitones were they recommended the some of the paint be scratched off to keep the case from shorting on the signal or usb ground IIRC.

Heya guys, I'm sorry if this is the wrong place to post this, you all seem to have quite a bit of exp with this unit, im very very new to it! i posted this as a new thread as well but its driving me nuts and id love an answer as soon as i can get one!

Ive hooked up a 4 way active setup to my p99rs, all focal utopia, atm we're having difficulties getting into the audio options menu (May have grounded the door wire so ATT is on all the time, locking me out of all audio settings ie crossover, ta, eq etc) my amps filters are on atm, but id like to turn them off! does the p99rs come with standard crossover points for each of the inputs. They're marked high, mid, low, sub, every things hooked in the right way. Id assume a deck as good as this would have a standard crossover for each of the outputs to protect the speakers when you first turn it on. I just dont want to turn the amp filters off and blow my tweeters. if anyone knows anything please help! very little info on this unit here in perth :S
