The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please ensure that the power of the adaptor is greater than the actual working power of the amplifier.What you get:1 * Mini amplifier blue tooth board1 * Shell (upper+lower)1 * DC line1 * Accessories as shown Review: Very large sound from a small board. Almost lossless distortion. I had another set up on the bench for an mini in-dash BT/FM/Aux receiver/amplifier, so I just needed to swap in the speaker leads and the power supply. Used my variable voltage supply at 12V-2A. Connected to a pair of 3" full range (60-20k), 90 db sensitivity, 4 ohm speakers, 40W (specs call for 50-100W input). No noise issues at all (others that reported this likely misconnected the amp/speakers). Bluetooth sourced from my Fire tablet, found the device in seconds. Volume set on max on tablet, then tried various volume levels on the amp, including full out on Classic Metal on Slacker (I know, LiveXLive), no distortion discernable. Speaker specs recommend a passive radiator for improved bass, this was just a free air test. Played on Piano Jazz on Slacker, awesome sound. I really like the switched pot they used for volume - simply on-off and volume operation. Only thing I saw on initial test was the volume seemed to go out well before Off position, likely due to the pot value used, I'd give it a 4.5 for that....otherwise a 5 overall. I have a few 24V power and torroidal transformaers I may try for a permanent power source. This may end up a desktop or portable bluetooth speaker Review: Se ve de buen material, falta utilizarlo ## Features - [Blue tooth amplifier] High quality mini amplifier board.
