If you're only getting 2-4 volts output at half volume from the HU on a 1,000W amp, assuming the deck output is good there is something wrong with that amp......do you have anything besides the ipod you can use as a source? Even running RCA's from another vehicle or a home receiver of some kind would help......

Looked up the manual here for your amp and looking at the control end you should be starting with the dials set (from left to right) at 11 o'clock, 8 o'clock, 8 o'clock, 8 o'clock.

If you get anything out of the speaker at that point....that's good.....

You will need to adjust them to get the most you can out of the amp, if you can't get a substantial output after trying that, it's time to pull the amp out of there and get it somewhere they can do some bench testing on it.....

Sounds like your amp is bad. Like Big Red mentioned it will have to be bench tested.

OK you have an ipod with a 50 Hz test tone right? If you have this type of cable then you're able to test it (bench or in-car). Disconnect the speaker wires at the amp end. Put them aside. Connect the ipod to the input and start the tone on "repeat" mode. Slowly turn the volume up while watching the amp output with your volt meter. If the ipod at max volume is unable to drive this amp to more than about a volt output then the amp has a problem. Could be the settings, could be something to do with the remote bass control, or it could just be plain old broke.

Edit: Make sure to turn the gain full counter-clockwise before starting. You can turn it up later if the output is too low.

Could use your head unit but that would not eliminate it and the existing RCAs from the test. There is a slim chance one of them is the problem. Do ipods not come with these cables?
