Bluetooth radio build.

Thanks for the link. This will be my next little project. How loud is not very loud? Do you think it is loud enough to hear over exhaust ?
It's not very loud but I only hooked it into one speaker. I'd say with two it would be better. They make I higher amp version that is more expensive it maybe louder. Idk how loud your exhaust is but I would say you could hear it it's not gonna be jamming out or anything tho. I do wish it was a little louder I should have left it on my truck and took it up the road to see if I could hear it over my truck because its loud! Lol I didn't think of that till just now.
