Looks like my stereo issue has been narrowed down to the amp. I purchased a used amp previously but it has the same problem as the original one.
I need a known working amp for a 2004. Anyone have one or know where one can be repaired.
Thanks very much.

 

i have one, ill pull it out today and send you a pic/price

 

Make sure that, not only is the fused B+ to the amp OK, but that the enable line is going high when you turn the AM/FM head on. Measure this at the amp's connector, not up at the head.
THis was an issue on one of the Facebook pages last week.

Thanks very much for this. Getting battery voltage on both b+ wires. But 6.3 on the enable signal wire when ignition turned on. Do you have any more detail on what might cause the low power and how to fix it. We have swapped in a known good head unit too and no change. It looks like power is getting to the amp but there is no measurable output from the amp. We have already replaced the amp once as well with no change. Going to try a third amp when it arrives.

 

it sold last night, once the qty become 0 it became unpublished on the website.

 

Does anyone have the ability to measure what voltage they are getting on the enabling line from the stereo to the amp. It would appear that we are not getting our amp to power on with the 6.3 volts we are reading. Thanks very much.

 

I can't help, mine is a Base model - no amp. Here is something you could try, cut the enable line and tie it to a known 12 volts.
I would assume, but do not know, that anything over 5volts would enable the amp but again I do not KNOW that for sure.

 

Thanks Rob, always learning!

Will give that a try. Thanks very much
