Amp isnt getting power

I have a 1 ferad capacitor hooked up to my 1000 watt kenwood amp. My capacitor reads 12 volts which is good but then when i hook it up to my amp it doesnt turn on. I cant get any power to it no matter what, ive tried it with all the speakers/rca cables pluggin in and also with them unplugged. My fuse inst blown but i replaced it anyways and it didnt do anything. I looked in the amp and nothing looks or smells fried. Does anyone know what it could be?

did you try or did you have power to the amp before installing the capacitor? i run an alpine mrp-f240 and one day i accidently let red(+) touch black(-) and i lost power to the amp, i thought my amp was fried but it was the ground that came from the sparks i guess. try checking the conections or try to power the amp directly without the cap.

It worked in my other car with and without the capacitor. I put it into my new car and it also worked both ways but suddenly stopped. I thought it was just the ground wire bc it had came undone once before, but then i saw that the capacitor was on. From there i tried many variations like with/without the speakers, rca cables, capacitor,etc. Also i tried another amp that i have that also wouldnt work. This made me believe that it had to be a ground or power supply problem but then it doesnt make sence bc my capacitor has power. I'm stumped:banghead:

sounds like the auto turn-on wire isn't connected.

yeah sounds like it, try using a volt meter to test it.
