Message If the previous installer didn't properly install the head unit, then they might have improperly installed the rest of the system.

It isn't that expensive to entirely replace the primary 12V+ wire, the negative ground wire, and the turn-on lead. Make sure the ground to the chassis in the trunk, from the alternator, and from the battery are good. You can check them with a digital multimeter.

You need a 12V DC relay with fuse installed inline on the head unit's turn-on lead to turn on the amplifiers. That is maybe $10 at an electronics store.

Do you know your alternator isn't the cause of the problem?
