I'm thinking of building boombox/ portable speaker, i have an idea how to make the box for the amplifier, speakers, input board and battery or transformer (im thinking to put 12v small car battery and transformer so i can use it to power it up trough main voltage or trough battery)
this is how i planned building it (this is rough demonstration)
I want to keep it on budget, i don't want to spend a lot of money on it.
What i need is some good amplifier board to run the speakers, 30W-50W per channel will be good i think 😀
What resistance speakers would i need? (4Ω, 6Ω or 8Ω?)
Should i make it with 2-way or 3-way speakers? What is better and why?
I want to build something like this because before thinking of building boombox, i wanted to buy a karaoke speaker but for playing music only i really did not enjoyed the sound and the bass of it, so i came up with this idea to build myself a portable speaker/boombox.
There are some videos on youtube building something like this but all of them are using car radio for input and output. Should i use car radio too? 😕
Edit: i fount these amplifier boards on ebay but i don't know if they are good (I was researching for some amp Boards and i found these. If you have some better suggestion for amp Boards please tell me.

How big you want or think to build it? that will drive the rest of decisions on what approach to take
Don´t waste time when all you want to know is here:

Just go straight to the source.

Garrbage I'm not sure how big i want the enclosure to be but i think around 50cm-60cm or 20inch-24inch (maybe a little more) in length, height idk depend on the size of the speakers and number of speakers and width im not sure but i will make it as compact as i can. First i want to get the electronics parts, then i will build the box to make sure everything its fitting.
JMFahey, I can see the post but can't see the images, the links are not working.
Sorry, I was not directing you to a single page but to a HUGE thread , over 500 pages 😱, containing hundreds of pictures, plans, detailed sizes, construction, speaker, battery suggestions.
Started in 2007 😱 so many earlier images are lost, just keep flipping pages until some start to appear.
A veritable goldmine. 🙂
Original idea came from designing a powerful yet portable system for Roskilde Festival, then it caught on like wildfire.
Start reading, just on the first page description starts, second page includes suggested speaker datasheet, and so on and on and on.
Just one example in hundreds:
Boominator porn?: just google images for "boominator speakers" 🙂
