I installed a Clarion DB179MP car stereo in my boat like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16882647080

Have a weird problem. I think I wired it correctly. Sounds great in tuner and CD mode. Balance and fader work correctly. Left is left, right is right, front is front, etc.

But when I play my Ipod through it using the AUX mode, only the left front speaker plays. If I change the balance to right, I get no sound. If I move the fader to rear, the right front speaker plays (poorly). No sound from the rear speakers no matter what I do.

No help from Newegg. They don't do tech support. And Clarion cust service is closed on weekends. Any ideas?

Is your iPod connected through a wire?? If so, smart money says bad cable. How does the iPod sound through the ear buds? If it is good through the buds, try hooking the iPod to a home stereo with the cable you are using to connect to the car stereo (may need a 1/8" to rca adapter) if that works well, then it may be a faulty AUX jack on the Clarion.

I second the cable. I have gone through 3 in the past 2 years. Quality sucks!

Do you play your iPod through other devices using the same adapter cord? If so, and it works well, I would suspect an internal connection issue involving the Clarion's AUX input Jack.

Of it has a USB or Bluetooth connection, try using the iPod through one of those.

I see from the pic that the "AUX" input is on the head, so that rules out a wiring issue on your part for the AUX section.

With your fader (and a good source like CD or tuner), set your fader to front and balance to left, then do the same type of thing systematically to ensure that you can isolate the audio to each of the four speakers.

Once you've determined that you have that working properly, repeat the process with the iPod connected to the AUX. It you had a mono jack or a bad cable, you should only get audio through either the left or right channels, but on both front and rear speakers. Getting audio though a front right speaker and (somewhat) through the rear doesn't sound like a bad cable. Either you've reversed one of the speaker leads somewhere, or the AUX section of the head unit is defective.

If you've crossed one or more speaker leads, it manifests in the audio as poor bass response...

Had time to work on this today. I picked up a new cable to run between the Ipod and and the head unit. I heard sound from more than one speak this time. So I concluded the original cable was bad. But I couldn't get the left rear speak to do much of anything so I ended up rewiring everything except the power input. It all sounds great now. (Well, as great as you can sound using cheap components.)

Conclusion: bad input cable and less than ideal wiring job on at least one speaker.

Thanks for everyone's input.
