[QUOTE="Toxxyc, post: 763436, member: 19314"] Should I in theory be able to connect two of these amps in series and run 8.5VDC to the two? I'm getting two of these to play with a bit, and I'm looking at different options for power, output, etc. etc. Just as a clarification question - the two output channels does not share a common ground, so if I understand that correctly it means I cannot connect them to the same driver? One speaker with two drivers (tweeter and midbass) if the input is a mono signal should be fine, correct? Finally, would two of these be able to run fine off a 1.5A cellphone charger? I know it's not completely as simple as this, but if the amp can produce 5W per channel and 10W in total, that means it would draw 2A at 5V at peaks, not true? Would that not hurt the power supply or damage the amplifier or something? [/QUOTE]
