Step-by-step explanation:
The power light for the Bose Acoustimass 10 Series IV home entertainment 5.1 channel system is typically located on the subwoofer. This is generally the case for many home theater systems, where the subwoofer serves as the central unit that receives power and sends signals to the other speakers.
