[QUOTE="akheathen, post: 8485288, member: 629234"] the other amp could be significantly lower power...... amps can draw 1-30amps just as a power-on surge, typically, and some can drop to 8v, and some need to keep 10.5v to start up. lets say it can pass 2amps and stay 10.5v to power up the power supply...... it might cycle the power supply if the wire or fuse can pass that much, but the amp spikes 4 amps and it drops to, like 6volts..... next test amp powers up on a 2 amp spike, or a 4 amp spike, but stays on at 8v+..... the test amp will power up and stay on.... but it won't stay on at any descernable power level. i've seen many amps not power up due to lack of current at power-on. my bench power just goes crazy..... add a battery, a second power source, or crank the voltage momentarily, (some cases) and it powers up just fine, and idles at under 2amps no problem...... the big key here is that the amp turned on when fed power to both remote and battery off the remote wire.... unless i read that wrong....
