I was wondering if anyone has tried any subwoofers other than the VSE bazooka in their new 2007 Tundra's. I was thinking of upgrading my system when my Tundra gets in...mine comes with the 6 speaker 6 CD changer system...is there any way to keep the stock amp and 6 CD-changer and add just one amp and up-grade speakers and add a "thin powered sub"(such as the one by Kenwood),and still have high quality sound nowadays. My other question is-what kind of speakers are on the dash in this speaker configuration? Thanks...DAcat
