Bose and Nissan have been working together for some time; Gwendolyn, at the advanced age of thirteen, sports a Bose-designed system (built by Clarion in Japan) with a speaker in each door, tweeters in the A-pillars, and a subwoofer dangling from the rear deck. Power is ostensibly 200 watts, though as a hi-fi buff for most of my adult life I have learned to treat amplifier power figures with the same mistrust with which I regard fuel-economy numbers.
The laws of physics being what they are, it takes some serious current draw to run these puppies at gut-thumping levels, and it is always better to have more amplifier power, not just for reasons that Tim Allen might endorse, but also because a high-powered amp that isn’t running flat out doesn’t produce as much in the way of distorion as a lower-powered amp that’s constantly bumping up against its limits. “Serious current draw” would seem to eliminate this sort of thing for electric cars, in which every extra watt cuts into your driving range.
Just the same, Bose is coming to the Nissan Leaf, with a similar speaker deployment but a head unit that uses half the juice. The press release doesn’t say, but I’m betting they’ve also removed the CD player, reasoning that the motor has a current draw of its own and that your average Leaf buyer is going to rely on his iPod to supply tunes anyway.
