Hi Harrison, if you mean the fuse for the main 12V+ cable that is at the battery, yes you need that fuse. If that cable should ever short to ground, the fuse will blow otherwise without a fuse you could have a real issue on your hands.@markboris This is a super clean install, and it looks like you have helped alot of people, that awesome! I have a quick question for you? Im installing a system that can take 12-24v do you still recommend the fuse from the 12v to the system or do you think I can skip it? Also any concern about the system staying on and pulling from the 12v?
Your question about the "system" staying on, you mean the amp built into the JL sub? If so, it will not stay on because you will have the remote turn on set to signal sensing. The amp will only come on when it receives and audio signal from the OEM sub wires that you connected to the input on the JL sub. When the JL sub amp does not receive an audio signal for more than 25 seconds, it will turn off.
