For whatever it is worth, the best vehicle sound I have ever heard is with a six speaker system (Infinity) with ten watt amps with each speaker.
Who makes an active speaker that isn't ported?
I'm trying to think of a 3-way active speaker that isn't ported and coming up with a blank. If someone does such a speaker, we could be looking at sonic nirvana.
