my system stopped working

Okay so i've had my system for almost a year now. And it's worked fine. Then all of the sudden today it stopped working. it was working earlier but it stopped working. My amp wont turn on therefor no power is going back there, but my capacitor will still turn on. The weird thing is my cd player won't even turn on neither. I checked fuse underhood and behind deck and they were fine. I'm stumped. Please help I checked my connections and nothing changed. I took my cdplayer out and plugged in another thing in the back to see if it would fit and it did then it wouldnt start back on PLEASE I NEED SOME HELP! Cap turns on and thats it. Thanks much, MikeHello.

Knowing what kind of car so we could tell you wich fuse to check would help.   Did someone plug a phone charger into your cigarette lighter socket?Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB
