The ends Pioneer and Clarion use and the Knu cables you are using, unless damaged, are not the problems.
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-sounds like you should cryo cool your wires. superconductor > standard rca cabling. I can get you access to LN2 or LHe if needed.
Erin, first of all, thanks for all your product reviews. I find them very helpful and educational. Much respect for you.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.
The JL XDs use standard terminals and they're smaller than the HDs.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.
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.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.
