You can also do a very simple technique as well, and easy to do.. tale a small piece of wire after you remove the existing remote wire and touch the power wire to the remote and see if it comes on?? if so this tells you that you have an issue/break or loose connection in the remote wire some where.Run a new one?? Make sure your fuse in the amp is good also.If it does not come on, you may have burnt out your last heat sink,get the amp repaired or time to buy another
