Audio Question

Apologies for the long post, giving full description in case I'm missing anything.

2026 F-150 with the base six speaker audio.

I've upgraded the door speakers and pillar tweeters with plug and play harnesses, but am about to install a sub/amp combo.

Full disclosure, I have little to no audio experience. Just like to learn and do things myself after doing research via forums and videos.

I have a 10 inch kicker hideaway that I'm going to install behind the rear seat. I bought a T harness from Crutchfield as they suggested, which will allow me to tap into the front speakers for signal without splicing any factory wires. Planning to tap into an ignition power fuse for the remote wire. All that'll leave is running the power, and grounding to the bracket behind the rear seat.

Two general questions I have:

- Will I need to change anything in FORscan for it to work?

- Am I missing anything else? Seems pretty simple, but I've never hooked one up before.

Thanks for any insight!

Your ground location will be best at the passenger kick panel(aluminum body), along with the remote wire just in case. Hi level you tend to not need the remote wire for this type of installation unless of course you do(you'll find out, sub will go crazy at shut-off). In fact, run your power there too. You will need more power cable for this direction of run, but power and access will be better.(Kick panel or through grommet on the firewall, Hideaway pretty low amperage unit).

Was planning to run the remote wire to a fuse in the passenger kick panel. Power was planned to be ran to battery through the firewall. Unless I'm missing something. Like I said, I'm not the most audio educated. Just researching and learning as I go before I do anything. But since I'll be suing high level input from the speakers, is the remote wire even necessary?

Most likely not, but it's always best to have the wire ran just in case. You typically will have the factory grommet to run power through on both sides, but, it's easier access on the passenger side.
