portable bluetooth speaker

Hello everyone,
I am trying to make a 5 Watt class AB power amplifier but I am having a hard time finding a credible schematic to go off of. Can anyone point me in the right direction?

Do you want to build it from scratch or a kit. A decent 10w mono kit runs around ten bucks.
The kits are nice because they come with a PC board.
Class AB 10W Mono Power Amplifier Kit TDA2030

What do you want to power it with ?

I like using IC's for keeping the parts count down.
A good basic circuit. Audio power amplifier circuit using Hi Fi audio amplifier IC TDA2613

I would like to use discrete components because I like learning how everything works in a hands on way. Part count doesn't matter to me, as long as the price is reasonable. And from scratch would be great.
For power, I would like to keep it as simple as possible. Since I want it to be portable I was thinking of an 11v Lipo battery. Idk what the best kind of power I would need, so I'm up for suggestions in that area.
Thanks for the help!

I found a nice schematic online, does this seem like it would work. It claims a 5W output with an 8 ohm speaker
