Al-Truistic

Any Echo drivers out there or does anyone know an Echo driver that rocks the dealer offered 8" Subwoofer option?

Different question but same...Is there a JDM Subwoofer that is different from the Bazooka? Is there an OEM sub offered for the ist or bB? What brand system does the bB/ist come with? I think they listen to music in Japan, maybe in their cars, too!

...there must be some pretty crazy sound systems over there, judging by some of their exterior mods.

I've asked about the Toyota sub offered for the echo, but I haven't heard good things about it. If you want to go an easier route, I think there's plenty of other powerd subs that would work well AND cost less.
