Good "accessory" wiring spot needed (1 Viewer)

[DirtScaresMe]

Finishing up a new subwoofer, and I need to supply power via the "accessory" mode. It's the connection that shuts the sub off when the truck's off since its main power is direct to the battery.

 

[DirtScaresMe]

I can tie into the red (acc) wire on the stereo harness I guess. Meh.

or off the ign switch or off the cig lighter

What NLXTACY said. I imagine this is on a stock stereo. Because on aftermarket stereos you have a amp or remote turn on.

Use an "add a fuse"

Use an "add a fuse"

Or do it the right way and don't. Tired of repairing those things.

 

[Chicken Hawk]

Repair what?

Why splice and compromise the factory harness when you don't have to?

 

[Fj81]

Especially on a truck of this age, it increases trouble shooting down the line when things get screwy.

Auxiliary fuse block.

Knock yourself out.

It's an aftermarket stereo with aftermarket harness, splice is beteeen that and factory harness.

Plus, it's for the sub so it shares same circuit as stereo and now cb.

Blue wire is remote turn on

 

[LandCruisinMy93]

Solid blue is amp remote power wire. As mentioned above.

 

[DirtScaresMe]

My metra 70-1761 wiring harness (bypasses the factory amp) notes that the solid blue is "power antenna".

Blue/white is marked as "amp turn on".

I think I wired my amps hot off the battery (with fuse), then remote turn on from stereo switched them on.
If you want real good performance add a 1/2 or 1 Farad Capacitor inline on your + side close to the amp.

I used to be an electrician in a former life; putting a capacitor inline makes a lot of sense for quick current. I'm rocking a small Kenwood powered sub; I can hear some bass but it's hardly enough to really thump.

But now I've got the wires run so I might drop some serious s*** in there in a few years.

Save the money. In-line capacitors do nothing for performance. Marketing scam. Biggest alternator you can fit, Big 3 wiring upgrade, and a big ass battery are all that help. In a limitless AC system in your home Capacitors can help, but in a closed low voltage DC ecosystem a capacitor can hurt performance. They look cool and make manufacturers boat loads of profit.
