So basicly what i want to do is put 2 speakers in a home made box
I have 2 speakers
2 tweeters
2 crossovers
1 2 channel amp
1 sub
And a head unit
Basicly I want to put them all in the home made box to be like a stereo
Except I want it to be able to plug into 120v and have 1 or 2 car battery's to run off of when it's not being powered by 120v
I also want the battery's to be rechargeable off of the 120v
I just don't know how to make all this work

The question is how am I able to wire everything to run off a cord going into 120v where does that cord go and with what wires
How do I make it charge the battery's as it's being powered from 120v (being the cord in the wall) and also playing the stereo
And what else do I need to make it work and how
Anybody that can help me with this at all will be greatly appreciated

You will need a battery tender/charger of some sort to keep the batteries charged. Getting the right amperage to be able to keep the setup running but to also not over put too much current to the setup. Also make sure to get a charger that automatically turns off when the battery is charged to help prevent overcharging.

Does that mean I need to wires comming out of the Box to do separate things? Or could I have just one plug?
And if it is just one plug does that mean it constantly have to be running through the battery's and the charger ? Or is there maybe a way I could put a switch in and bypass the charger and battery's?

What you want to do is fairly straight-forward, but first I have a couple questions.  1) how are you powering the subwoofer? How many watts?  2) you mention a "2-channel amp."  What's it for and what's the wattage output?  3) you list 2 tweeters, but what about your main full-range speakers?  4) Do you intend for this to be portable?

Put everything in one box, the way you want it. Make certain you have enough battery to power your amplifier for the time you want to run it.

It's going to take a bunch, I promise you. The thing's gonna weigh a ton. You'll have to have those, plus a 5 to 10A charger that will charge the batteries when you plug it in. Get one with an automatic trickle charge, or else you'll boil them dry in short order. To minimize this issue, you'll be better off with an AGM (Absorbed Glass Mat) battery, ala Orbital (aka - Optima). Expensive, but more reliable, and safer - MUCH safer - in a "portable" application. Chances are also VERY good that you'll have 120Hz hum in your system when plugged into the wall.


"Battery's" shows ownership. "The battery's 'WHAT'". The word is batterIES, the plural of (meaning more than one of) battery. End of English lesson.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
