[QUOTE="Robert Burns, post: 22912, member: 76"] Re: 12v Eco project sound system I thought the "structure" was fairly small - that lowers the power demand. There were variables and considerations in your scenario ( as I recall ). I suggested using car stereo amps for various reasons: there is a large existing pool of amps to draw/recycle from. Car amplifiers first setup up voltage internally - this increased voltage means decreased current flow and the internal components/wires and circuits paths can handle more power. Not to launch a huge debate on Class D, but IMVHO the efficiency/weight strengths of the design is vastly over-hyped, and [U]real[/U] good quality class D amps don't come cheap. And the disadvantages weight/inefficiency and heat of the others classes is over emphasized. Amplifiers don't have a duty cycle like a resistance heater and their energy consumption pales against something like a plasma screen or stage lights. Assuming this is a permanent install(?) then weight and size of speaker cabs is not an issue? ( I couldn't give an honest objective opinion on appropriateness of BF designs in your scenario ). Since I don't know what that genre demands in terms of LF that's an important variable. [/QUOTE]
