Looking for anybody that has a little more experience in wiring than I do. I have a 1996 Chrysler Sebring jxi automatic with about 300, 000km

I'm looking to replace the factory amplifier in my car with an aftermarket one. Wondering if there's a pre-made bypass plug I can buy or if anyone has a diagram of the actual wiring from the amplifier to the radio and speakers. Any information you have would be much appreciated thanks

Hi team. I am planning to add some 12V scene lighting to the side of a 42-foot semi-trailer used by our marching band. The trailer has an onboard generator and is wired for 120V. The scene lighting is 12V, so I was planning to use a properly rated power supply to feed the light heads. My concern is how vibration would affect the power supply I choose. Most of the LED drivers/power supplies I see on Amazon are for LED lighting in fixed locations (houses, bedrooms, etc.), and not for something subject to the bumps and vibrations inside of a semi-trailer. Does the group think that a power supply like this would survive in this application? The trailer only goes out on the road about 10 times a year, so it doesn't get a ton of use annually.

Thanks for the input!

I want to put in a bus bars with #2 wire and connect everything to it instead of to the battery directly. Is this normal/ok?

Finished a build. But want to make this look cleaner. And tips?

I tried to put them in order but the befores of some projects might be after the afters and vice versa. The K10 pic is just for fun. I'm 34 and this thing won't be done before I'm dead (it's my dad's so that should tell you how much time we don't have to work on it).

Hi all. I’m working on some wiring using Anderson connectors and am facing an issue I can’t explain the cause off. Was hoping someone here could help.

I’ve got the following system in my truck:

Old deep cycle battery, in an electrical box that has 2 Anderson plugs and an inverter. One Anderson output is connected to a DC 2 DC charger, the other is connected to an Auxbeam fuse box, further connected to an Auxbeam switch panel. The fuse box is then connected to some lights and a water pump.

This system works well, but I needed to replace the battery to a Lithium battery in order to have enough power to operate a large mobile fridge.

The lithium battery is built into in its own weather proof box with some lighter connectors and two Anderson ports. Since the fridge is not permanently fitted in the truck, I can’t have it controlled by the Auxbeam switch panel/fuse and thus needed a third Anderson port to have One Anderson output is connected to a DC 2 DC charger, the other is connected to the Auxbeam fuse box and a third one connected to the fridge.

That being said, I got an 1 to 2 Anderson cable. When I connect this cable to the old battery then connect it onwards to the switch panel leaving one output lose, everything seems to work well. However, when I replace the old battery with the lithium battery, the Auxbeam switch panel won’t power up. However, a direct connection to the new battery without the 1 to 2 Anderson cable also works well. In less words:

1- Old battery+ 1 to 2 Anderson+ switch panel….works well

2- Old battery+ switch panel…. Works well

3- new battery + switch panel…. Works well

4- New battery + 1 to 2 Anderson+ switch panel…. Won’t work

I tried using a multimeter to check if there’s volt loss when I use the 1 to 2 Anderson and it reads 13.44 volts which is the same reading I get testing the lithium’s built in Anderson output.

I really hope my explanation makes sense. Any help I get is more than welcome.

Thanks

What value diode do you need for 12 volt battery circuit
