[QUOTE="Crankshaft, post: 921341, member: 941"] I have some very nice 5S3P 18650 Li-Ion batteries that charge up to 21 volts. So, a class D amplifier module that operates between 18 - 21 volts could work. There are three speakers to drive; I'm wondering if I can use the 'classic' car-sound topology where one connects to sub to the 'outer' to terminals of the amplifer - ie. +ve of one channel and -ve of the other? Otherwise I will have to get a miniDSP or similar and a 3 channel amp. [/QUOTE]
