Hey all,

I recently installed a new head unit, in order to get it to power up i had to connect the antenna to power, however i have no sound, I checked the fuse for the radio but all seems well, im not quite sure if i have bypassed the stock infinity amp however.

My question is

A. How do i know if its bypassed
B. Does the stock amp have a fuse i may have blown? I cant see one.

Appreciate the response
