Audio Help Please

[kosko]

I installed rear speakers in my 07 3dr hatchback a few weeks ago. I have had no problems since I did this, however just 2 days ago I began my install on the front (and wired the passenger side first). My commute is only about 45 minutes, and I had no problems on my way in to work listening to the radio, cd's or my IPOD.

The issue is that by the end of the day (on my drive home), I was listening to my IPOD through the AUX input and the sound just cut out... Confused I turned off the factory HU and unplugged my IPOD to see if anything would ork with just the radio, and it did come back on. The problem is that my HU turns on and functions but I don't get any sound, and then I do get sound, then sometimes it won't put out sound and other times it will but then shut off...

Anyone run into this problem or have suggestions? Any help would be appreciated!

I checked the fuse and it's fine, and I don't think I melted the HU since it still comes on and works sometimes (I double checked all of my wiring and its all perfect).

Please Help!
