i'm sorry gnntta, i must have half asleep when i replied to this post. bigger is not always better that is true, the topic was about another alternative towards a 3.5" coax speaker. I had the infinity reference in the stock location. i was not impressed. you talked about using a 5.25" in the door, but the concert II sound baffle accomodated a 4x6 speaker. are we talking about a stock look? or did you make alterations to fit the 5.25? skys the limit with sound systems and designs. i was just throwing out ideas and didn't mean to bag a company like BOSE, who i like and use at home. i was thinking of supplying the midbass upfront with larger speakers would be the way to go. so sorry for the confusion.
