[robertr81]

Hi,
First post 🙂
Planning on building a 12v boombox with a single coax 6.5" speaker (mono).
I found this amp:
(50w mono amplifier board TDA7492MV Class D)

Is there a better alternative?

What is the best batteries for this project?

Thanks
/Robert

At least the author can almost understand the English language so this is probably the better of the two.

Thanks for your reply.
So based on the seller's language skills, the second one is better?
