Was wondering if anyone had installed this in their S? I heard this while at Best Buy and it sounded great I think better than the Polk DXI650 which is found here http://www.bestbuy.com/site/Polk+Audio+-+6...7&skuId=9985099. Here is the info for the Alpine http://www.bestbuy.com/site/Alpine+-+Type-...5&skuId=8699429. Will these Alpines fit my AP1?
