What bluetooth amplifier should I buy?

I don’t know much (anything) about picking the right amplifier for the speakers. Please help.

I’ve got four Clarion CMG1622R speakers I need to hook up.

I’d like the amplifier to be bluetooth and able to plug into a standard wall outlet.

Since I have 4 speakers does that mean I need an 8 channel amplifier!?

If you wanna just link to the right amp I’d greatly appreciate it. The cheaper the better.

THANK YOU!!
