Why won't amp get power?

370zhtx · 10-18-2016, 02:57 PM

I had everything installed and running perfectly couple months ago and then took out the amp and subs.
Last night I put everything back together and the amp won't get power. I have already done the following:
Check fuse on power wire
Check fuse on amp
Check fuse for audio and bose amp under dash

What I have found out is this:
When connecting a 12v led to the power cable at the amp and negative to the ground, the led won't light up. When connect it to the remote wire and ground it lights up.
When I connect the power wire coming from battery(right after fuse) to led and negative to terminal it lights up only when negative wire is dissconnected to the car. When I connect the negative terminal to the battery there is no power going after the fuse.

Please help me out as I am totally stuck now.

When uninstalling and installing everything the negative terminal was disconnected.

Turned out to be the fuse by the battery terminal. Even though the fuse looks perfect.
