Pi3 Car Audio

Sat Nov 11, 2017 10:36 pm

Hey Guys and Gals,

It's been awhile since I've posted on here.. I've got a new project, hooray!

My brother owns a 1979 Ford F-150 Custom.

Current Specs:
Engine: V8 6.6L 400 Crate Engine
Carb: 2 Barrel
Tires: 35" MT Toyos

I've slowly been fixing it up, and working on as much as I can. I recently put a stereo system in it. I went into a store around 5PM last Friday, and I came back to my window broken, and my $200 stereo system missing. Anyways, here's my goal.

I want to put a Raspberry Pi 3 in the stereo location with a few features.

Speakers: 2 Door speakers
Sub: 2 small 10" subs (Give or take 1 if needed)
Screen: 7" Touch Screen or if 10" is available.

I'm fairly good at programming, and I figured I'd write an application that'd allow you to connect to your phone via Bluetooth and control the stereo system that way, as an option. IF you have hotspot available, you could use that to stream music, music videos, etc..

I can do almost all of this work myself with little to no help, however I'm stuck at how to connect the screen + speakers to the Pi 3. I've never used any GPIO parts, and I'm rather curious about it.

My other issue is, power. This truck's alternator should crank out enough power to handle everything, including the small subs. However, I don't want it to drain the battery when it's not in use. I've also thought about putting a battery block into the vehicle to be used as the power source to keep the Pi 3 online 24/7, however I'm not sure how safe that'd be.

Thoughts/Suggestions?

I saw another post on here using; https://elinux.org/index.php?title=RPi_ ... ards#Sound

Will any of that be useful? My friend sent me this; https://www.hifiberry.com/shop/boards/hifiberry-amp2/ since I'm looking at hooking up only 3 speakers.

Regardd wiring more than the 2 speakers to the Hifiberry Amp see:

Please note you need to shutdown the Raspberry Pi correctly, pulling power can lead to data corruption.

Well.. Thanks for the feedback guys. Not sure how that car pi is similar to my project, I won't be using a tablet for a screen. I plan on custom building all the apps for it, and utilizing bluetooth for some things. I'll take what I can get though.

One question; can you use more than one add-on with the GPIO? After speaking with my brother, we're skipping the subs for now due to the truck having a bench seat. No where to put the subs, and we're not modding the cab to fit them. So, 2 - 4 speakers total.

Regards GPIO, yes you can stack more than one HAT / board if they are designed to do so......
