Howdy everyone,
I've been reading through all the amazing knowledge and talent on this board and decided to register and try you guys out for an answer to my wiring question.
First I'll explain my thought process and plans, then the question/s.
Thanks in advance.
Project: portable boombox (consists of 12v car stereo, 4 speakers, power supply and battery).
- I'll be using a 12v 30a switchable power supply to convert 110vac to 12vdc.
- I also plan to use a 12v 9ah battery so it will be mobile and able to play at camp sites and such.
- The battery will recharge via a battery charger/tender that I will plug in when needed (and eventually a small solar panel, and power controller for off-grid charging). These will obviously not be a strong enough charge to maintain the battery while in use, but that's not my goal, so it's not an issue. I'll just use it and recharge when I need to.
.
Side note, the wire for the stereo to provide power to retain the memory/programming in the cd player will be directly wired to the battery. With this thought, I wonder how I will maintain a complete circuit for that, if I switch to the power supply feed instead of battery. (This may be answered with my question below, if the answer to that one is what I’m thinking it is)
Also, I was originally going to run the CD player straight off the battery and have the power supply maintain it but then it started getting difficult for me to figure how to keep the power supply from over charging the battery, other than manually monitoring it, which is why I decided on two separate systems. (you know. to simplify things. haha right)
- - With the two separate systems concept, I can't wrap my brain around ‘how to wire the switch between the two systems’. In a house, you have a ground, in a car you have a ground (anywhere on the frame or good metal attached to the frame).
In this system.. ???
?? - Do I connect the 12v negatives of the battery and power supply together as one circuit, and then wire in a toggle switch that would have the battery 12v+ on one side and the power supply's 12v+ on the other side?
Or do I need to keep the negatives of each system (Battery and Power Supply) separate from each other as well?
Thank you.
