my front speakers and tweaters work, but my rear doors and rear deck speakers dont... anyone want to take a crack at this??


speakers are replaced but wasnt working before anyway so its not the speaker per say..
wiring perhaps?? i dont even know where to begin to trace the speaker wires

factory amp perhaps? i dont know.


HELP!

also if i take out my amp will i have to enter my anti theft codes?

 

I assume this is a TSX?
If so,
The rear deck and rear door speakers are feed from the rear output of the HU. The factory amp splits the feed for the deck and door speakers. If all of the rear door speakers are dead then first check the fader setting on the HU (audio setup). Make sure its in the center. If it is then it is unlikely that something broke in your amp that would cause only the rears to go out, not impossible just unlikely.

The next thing is to see if you are still in warrantee and bring it back to Acura.

If you are out of warrantee and want to fix it yourself I’ll tell you what to do next.

i am definitly out of warranty. its an 04 navi tsx. mind i dont have access to much tools just the basics. but yes i would most definitly like to fix this myself. thx

 

OK,
Go to the Audio FAQ section https://acurazine.com/forums/audio-video-electronics-navigation-22/%2A%2Aaudio-video-diy-info-faq-all-models-%2A%2A-299065/ and scroll down the to TSX area. Read all the info on removing the center console (follow the links and look at the photos) and accessing the amp.

When you have access to the amp remove and reseat both plugs. If this doesn’t fix it then you will have to check for signal from the HU. You will need access to a Digital voltmeter DVM or an old fashion analog AC voltmeter to do this. It is not to hard to do but try the reseat first.

thx jeff i will do that today. i didnt even know u could "reset" it like that by just unplugging it. i will update later thx

 

You’re not actually “resetting” the amp, sometimes the connectors are not seated properly or develop a poor contact. Reseating them can correct this.

jeff

 

alright, just got done unplugging n replugging and to no avail =(.

 

ah almost 4got since im half done taking apart the console, how do i remove the actual radio and navi? i didnt find any thread removin the navi is it just clips n i just pry? i want to do this so i can get the s/n off so i can get my anthi theft code

 

When you find out how to remove the radio post it. Someone was looking for that info last week!

Back to your problem, the next thing to do is check for output from the HU. To do this you need an AC voltmeter or DVM. Do you have access to one?

jeff

 

sigh, no i dont =( i can probably (big probably) find one if i do what will i look for and if i dont is there any other "short cuts"?

btw thx jeff ur being very helpful =]

 

You can pick up a meter cheap, anyone of these will do but the digital one is easy to use.

believe it or not , there is no radioshack around here, i live in jacksonville nc, and theres only hic garages and autozone...thats about it. but fourtunatly i wear a military uniform and i can get my hands on a volt meter digital. soo we can go from there. what is my next step?

 

The signals from the HU are on the smaller 14 pin connector. Remove this connector from the amp. With the connector off it is a simple mater to test to see if the HU is working on all four channels.

Check post #13 here https://acurazine.com/forums/showthread.php?p=5283595 for a picture and pinout of the 14 pin connector.

Set your meter for AC volts, if the meter has a voltage range selection set it for the setting nearest to 10 volts.

Turn the HU on and be sure that some music is playing. Set the fader and balance to center and set the volume to 30. You won’t hear anything with the amp unplugged.

With the voltmeter check for a varying voltage on the following pins list below. The voltage won’t be steady; it will vary with the loudness of the music. If all the outputs test about the same your HU is good.

Just touch the voltmeter test leads to the contacts inside the large holes. Don’t push too hard or you might bend or pop the pin out. If the test probes are too fat you can use a paper clip. Don’t let the probes or pins touch each other.
