Not so much to be louder but fuller. With speakers in few locations, you may be inclined to play it loud to hear it up front. Being surrounded by more speakers would allow to play at a lower volume and still be heard.Not to sound rude but i dont even understand the question, why would somone want their speakers and system to sound louder??? Well where im from the real question would be who wouldnt want their speakers even louder lol. Most people i know upgrade there speakers and systems soon as they get a new car, especially if you have jeep or bronco and the top and doors off you need a louder system then normal. And also from what i heard the B&O system in the bronco and some of the other fords leave a lot to be desired, i have friends that told me if you are getting the lux package for the upgraded speakers that it is not worth it at all, and your much better off saving that money and having better speakers put in at a local radio shop. But some people dont like the music up to loud which to each his own, but i know a louder system will be the first thing done to my bronco.
