Re: 12v Eco project sound system
12v will limit the power you can easily generate. High power car systems use DC to DC conversion to get higher working voltages.
dB at what distance? 100-200 indoors? outdoors? inside a phone booth?
yes- this will allow you to you the most efficient driver for each bandpass, without passive padding to balance levels. And using individual amps per bandpass will give you more effective power, than one single larger amp of the same combined power.
Indeed class D, will give most output from battery. Tripath is not the only class D option.
Perhaps an old school folded horn for the sub... definitely a high efficiency design.
The heavy bass will eat up power and amplifier headroom, so you may want to lower your expectations for lots of deep bass.
Good luck... you have started in the right direction...
