kenwood dnx5140 install issue - Page 3

..... now i'm not sure. I mean.... i may be mistaken, but it seems a bit odd. when i was messing with the audio before, i messed with the fader. I don't remember which was which, but i think if i faded to the front, i'd hear more sound throughout the speakers, but if i faded to the rear, it would only come out of i believe one woofer and the opposite tweeter..... or vice versa. That kind of makes it appear to have something to do with how the under seat sub is powered by opposite tweeters and woofers. Fading to the left or right worked as one would expect. Guess i'm gonna have to look at the wiring a bit more, make sure nothing is loose or improperly connected..... maybe check the radio pinout diagram from Evilution and compare it to what's connected to both harnesses. Also thinking about possibly taking it to the place that installed the speakers for me to see if they could fine tune the audio a bit or something.

Please double check your wiring based on this page:
Evilution - Smart Car Encyclopaedia

It appears speakers are specified as the middle two and tweeters are the outer two of the middle connector (top of the two connectors that are part of the harness). What did you wire up?

Does balance right/left work? How about that with and without fade? You should be able to select each of the 4 corners with balance and fade in the four extremes.

Good luck here.

Well..... i didn't really wire it up myself. the wire harness from 4smartcar kinda helped with that..... unless their harness is incorrect.

left and right balance seems to work fine from what i remember..... it's just when i fade to either the front or back that the speakers seem a bit off. Seeing as it's now 4AM and i need some sleep, i'll have to update again sometime tomorrow... or later in the day, depending how you choose to view it.

ElementalDragon · 07-05-2009, 03:18 PM

yea.... gonna have to check the wiring. it's more than likely something with the harness that's incorrect, or maybe something with the crossover for the speakers that's not quite right now. If i fade and balance it to the front left, i hear sound from the woofer in the left door. rear left and i hear sound from the left tweeter. front right and i hear sound from both the right woofer and tweeter. rear right and i hear nothing. and none seem to help with the under seat sub either. that still only really seems to work with the Tuner.... which is kinda odd, since AFAIK, the sound settings are for the most part the same no matter what input is used.

There is no crossover in factory speakers. Tweeters have a simple high-pass filter, no filter on the "woofers" in the doors. I'd imagine your right wires have a couple wires swapped so the right speaker +/- has one wire going to the speaker, one to the tweeter and the other wires hooked up to right tweeter +/-.

The settings in your head for balance, fade, equalization profile, bass boost, or whatever are probably specific to each mode you're in. The radio can have different volume and equalization than the iPod or CD. Once you have the right speaker and tweeter behaving properly, the sub should work with the correct equalization.

I'm wondering what would happen with the sup if the speaker and tweeter inputs are 180º out of phase. No output or properly accounted for?

ElementalDragon · 07-05-2009, 04:32 PM

well.... i guess i kinda forgot to mention the fact that i'm not using factory speakers... hence the reason why i mentioned a crossover.... which is neatly tucked behind the head unit. Probably gonna have to take it down to the place that installed the speakers and see if they can figure something out.... although i don't know if that's possible seeing as the crossover only has positive and negative for input, woofer, and tweeter.... so i don't see how that would be able to fade between the front and rear.

Whatever, guy.

Good luck.

..... uh huh.... hate to say it... but that's quite a bit of arrogance there. Explain this to me, if you think that what i said is so contradictory. If there is only one set of positive and negative terminals on the crossover for audio input, one pair of positive and negative for woofer output, and one pair of terminals for tweeter output.... exactly HOW would separating speakers be possible? In short.... what you're basically saying is 1+1=4?

Just took it down to the place where they installed the speakers, and even he said he has no idea how the hell the speakers on the left side are being separated...... that they SHOULD basically be working like the speakers on the right side.

And no.... i didn't just make that up about how it'd work after being down there. I knew from the start that separation would probably be impossible. Only reason i bothered to go down was to see if they knew why the left and right speakers were acting completely different. He told me to bring the car in on Saturday so they could look into it.

Arrogance? You gave me conflicting information saying that the fade produced differences then suggested the only audio elements you had were set up for one +/- on each side. You're probably ignoring the windshield-located tweeters in the front of the car.

Frustration. You've given limited information and expected answers. I've tried to be helpful as the only person providing any advice. You say fade can't possibly work yet it has an effect on one side.

There is no pair of positive and negative for woofer output. The woofer taps the wires directly feeding one door speaker and the windshield tweeter on the opposite side of the car to try to give full output for your fade and balance settings. The two speaker channels (center pairs on the connector) should be hooked up to your door speakers. The two tweeter channels (outside pairs on the connector) should go to the tweeters located under grills directly outside the air vents for the windshield. The subwoofer is connected to two channel pairs, one of each type.

What I'm saying as far as the effect of fade on your system is that what you hear are the woofer/tweeter/crossover components AND the windshield mounted tweeters at the front of your car.

If you have the factory subwoofer, you have the tweeters up front.

And by the way - while not an audio guy I am a degreed Electrical Engineer with 20 years of electronics design experience and a keen knack for troubleshooting tough electrical problems in complex systems.

If you choose to insult me again, I'll just add you to my ignore list. You've been incomplete in other threads, too, and I don't care to try to help those who choose to be rude when they, themselves, cannot provide a solid enough foundation to provide good answers. If you choose to continue the thread, I'd suggest you ask for help from others rather than responding to me for more help.

Good luck.

Ok..... let me try to lay it out nice and neatly for you.

Aftermarket Kenwood DNX-5140 in-dash nav head unit
Aftermarket Hertz HSK-165 2-way component speakers
stock speakers have been removed, both in-door woofers and dash tweeters
Wiring harness from 4SmartCar used for HU installation
Driver's side speakers somehow fade front to back and are able to output to either the tweeter or woofer independently
Passenger side speakers appear to be working as they should, being unable to separate the tweeter's output from the woofer's

The in-dash tweeters are no longer there, otherwise i'd have considered the idea that maybe that was the cause. It's just that somehow the tweeter from the Hertz speakers is able to separate itself from the Hertz woofer... and it's quite puzzling as to how it's doing so.

And i didn't mean that there was a pair of positive and a pair of negative terminals for the woofer. Guess i kinda meant to say "pair of terminals" for both the woofer and tweeter.... but for some reason put "positive and negative" instead.

And the reason i said that was because rather than taking the time to ASK a question, you seemed to just assume that something you were assuming was the case, unless specifically told otherwise at some point throughout the conversation. Kinda thought that maybe the fact that i mentioned possibly taking the car to the place that installed the speakers in post #21 may have tipped you off that it's probably not running stock speakers, either. Hell, the main reason i replaced the stock speakers was because i was planning on it at some point anyway, but i just couldn't stand the screech from the seriously overpowering tweeters in the dash. would loathe the sound created from having 4 tweets and 2 woofers.
