Thanks for the acceptation on this forum. Im kinda new on this beautifull univers and i have some noob questions.

I wanna do a portable bluetooth speaker, made in wood like a lot are doing it.

But i have some questions about the speaker power/ ohm.

The board i plain to order is a bluetooth board TDA7498 , 100w each and accept 4 ohm until 8 ohm.

I wanna try to put 4 speaker in total, 2 full range, 2 tweeter and 1 passive for the bass ( or two )

Should i go for a 8 ohm one's or 4 ohm one's ? And if it's 100w by channel can i go for example 30w full range + 30w tweeter on each side ? Sorry for the noob's questions haha and thansk for your answers

I heared also that the voltage on battery is important and some told me to go 24v instead of 12v battery. The board accept 12v to 30v max.

Actually i have this in my card :

2x 30w 6 ohm tweeters
2x 20w 4 ohm Full-range speaker
2X passive radiator 120mm ( maybe too much ? )
1 x board TDA7498
1X 25.2v Panasonic 12000Mah battery.

And then i need to order power button for this.

If i connect everything together will it work ? I miss something ? Calcul aren't good ?

Sorry for all thoses noob questions but i wanna be sure to start with something good :)

Will it work
