Re: 12v Eco project sound system
If you're talking about US dollars, $1000 for sound, considering speakers, cabling, amplification, processing, etc is very difficult to pull off. You could easily spend that on amps and DSP alone buying what many would consider to be quite entry-level items.
I also think that hoping to build a BF design for $150-200 is pretty unrealistic when you factor in all of the costs. Consider some of these: speakers, plywood, connector plates and jacks, wire, crossover components, construction adhesives, saw blades, sandpaper, filler, paint, handles, corners, grill, feet, etc. The little stuff really adds up, even if you use the cheapest drivers.
