This confirms that it does not take much power to run tweeters effectively. I wish they had some ultra portable 2-channel amps you could easily wire and power and install behind or under the head unit to drive tweeter channels. Something like the small Alpine power pack or the amp that comes with the Japanese DEX. This would really simplify matters, especially if you have rear door speakers consuming amp channels like my car does.
