have read a few posts here and there about the sound system in the Sedona's been of poor quality ..... And the posts are right the standard Stereos are crap I removed ours and fitted the Sony xplod from our Shogun and the sound is totaly different so dont change your speakers just change your head unit !!! I fitted the head unit from the Sedona into the Shogun and the sound is sh*t !!! Speakers in these cars are spot on.
