I recently bought a used 2008 Outlook XR which has the optional "Advanced Audio System" with 10 speakers. I am surprised and disappointed that it just doesn't sound very good to me. The highs in particular is very weak. For comparison, I have an Isuzu Trooper whose stereo sounds about the same to me as the Outlook (i.e. marginal), and a Saab 9-5 that sounds MUCH better. These are all stock factory stereos, so I'm not a picky stereophile. I checked all the front speakers in Outlook, including the side pillar tweeters and the center dash speaker, and they do seem to be working, but they just don't put out much sound. I'd like to hear other people's impressions of this system, and I'm curious if anyone has improved it significantly by replacing speakers. Thanks.
