Should be and easy one for you guys...

I put in a 2 channel blaupunkt amp amp for the fronts and added some tweeters. Last night (engine off) it didn't come on immediately. Second, third, etc attempts (engine still off) worked well. Today I'm buttoning up the work.

No longer comes on line.

I have checked the voltages at the terminals:

Radio off: Hot/ground 12.39 or so V
Ground/trigge: 0 V

Radio on: Hot/Ground: about 10.39V
Ground/trigger: 8.55 V

I thought maybe the battery was dying so I started the car and I get similar Voltages and the amp still won't come on. Amp is wired directly to the battery 20amp fuse, 10 G wire. Amp is under the drivers seat (when I put the seat back in). Any guesses? I can't figure why the voltage would drop with the radio on (and engine on).
