[QUOTE="SlugButter, post: 8837623, member: 678073"] The bluetooth speaker probably actually runs on DC power with a power inverter. Youre taking 12 volt DC power, turning it into 120 volt AC power, then the Bluetooth speaker is turning it back into DC power again. You’re losing a ton of amps in this process. You’re probably running at half power. I made a stereo for my daughter EV BMW using 5 18650 lithium ion batteries and a bare amplifier board. In the house it runs on the 24 volt DC inverter. The 150 watt RMS amp I used requires a 24 volt inverter at 3.2 amps to run at the full 150 watts RMS. [/QUOTE]
