Some ideas to a 12v custom noice filter.

Hi Forum.

I hope that some of you guys can give me some inspiration to a high-end noice filter that operates in 12v DC.

This project of mine, is making a true HIGH-END automitve audio system, so i use some parts i know sounds grate, from our home systems.

Ive made a drawing, which you can take a look on - it isn't with the right symbols, but i can read diagrams, so if any of you has an idea, to a filter / Ground Loop ect. then you will be a fantastic help.

as you can see from the drawing, the DAC has to be switched on with the engine from the car, it shall not have power directly from the acc. The Transport and the Router, gets power directly from the acc, and one thing to be aware of, is that the Transport needs 12v aswell as 5v.

Best Regards.

One of the problems in a car if you're going to be running a DAC is that you'll need a preamp as well because a DAC has no volume control.

What are you planning to use for amplifiers?

What have you used for speakers?

What are you doing to control the resonances of the body panels?

I've built sound quality cars before, and the improvement from running a seperate DAC vs a quality head unit is minimal compared to the other questions I've raised. Until you've maxed the setup of amp, speakers, sub enclosure and properly deadened, stiffened and insulated the car you're wasting your time.
