    I'm not sure which would be best suited, a 12V 2A or 12V 3A Power Supply to power a 15W Amplifier (2*15W Outputs) and a Bluetooth Module.

    I thought that since the amp is using around 30W output (2*15), it would need about 12V 3A in alone (probably a little under that), but the bluetooth module would use a low current so i thought 12V 3A would be good, but on the Amplifier link it says it uses around 12V/2A so now I'm not sure.

    I'm not sure if that made sense ^ but any help would greatly be appreciated. Thanks.

    if in doubt go for the higher output. the PSU will only deliver whart the load calls for, so a 3A supply might only run at 2.5A whereas the 2A supply would struggle.
