Other users have connected successfully the spectrum analyzer to the line out of their car cd players. I don't know why you are getting that strange behavior. First you should check that signal is really coming out on that line_out port maybe you need to activate it somehow and once you are sure signal is coming from the line-out you should check the connection (cables,connectors,etc.) up to the spectrum analyzer. If everything is okay up to this point I see no reason for it not working.

The spectrum analyzer is designed to be plug and play with a standard mp3 player output which is pretty much standard across different players. It was not designed to be plug and play with car audio players but as most car cd players have a line out connection which goes up to 2V it is possible to connect it to a spectrum analyzer as that is within the limits of the spectrum analyzer. The onboard pot also helps adjusting that input level to get just the right amount of level showing on the analyzer.

There is also the option of having it installed by someone with experience in car audio setups.

May I contact one of the other users that have connected successfully the spectrum analyzer to the line out of their car cd players?

Sure, I kindly asked on of the users who successfully connected it in a car to post this opinion on this subject. His reply should come soon.

I believe some head units also allow you to set the output voltage for the line-outs. Most of them these days are just stuck at either 4 or 5 volts.

Hey 20ducks, I read your posts and it sounds like you have hooked everything up ok. The analyzer is a very touchy piece of electronics, it took some work
but there is a sweet spot there. What I did to get it working was: 1) Make sure you have a signal coming from the line out of your deck which ever line you use(l use my sub outs, l will explain why later). 2) Make sure motherboard and led's are connected properly. 3) Turn the pot all the way down on the motherboard. 4) Power up the analyzer. 5) Turn up the volume on your deck about 3/4 of the way. 6) Slowly bring up the pot till you get the led's to hit that sweet spot where it looks good. The problem is you have to leave the volume of your deck at or around this general level all the time to keep your led's
looking good. That is why I bought the Clarion EQS746 passive eq, it has it's own voume control and since it's not connected to the analyzer it does'nt effect
the led's. This little eq kicks ass, it raises the line output to 7v wich made my system sound ten times better, especially the subs and the blue lights look
good to. I have attached a picture, i am trying to get some video but the glare is hard to work with and i want to show everything not just the lights.

Looking forward to ordering a new motherboard and re-installing my unit, successfully this time!

Please post or message me when a motherboard will be available.

Thanks,
