my amps power wire came disconnected and touched on the outside case, and now it doesnt work. i have power to the amp the light doesnt come on and it makes nop sound nada where do i start trying to find the problem i never worked on electronics before! its a bostwick ma-280x

 

id start by opening it up and see if there is a fuse in it. mine have 2 fuses inside.

 

check the inline fuse from the battery to the amp


edit-just noticed you said you had power going to the amp

 

Yea, definitely start checking fuses. Its probably the fuse inline towards the amp. The one closest to the battery.

 

since its a cheap amp id say its toast.
