Ok in a box chevy the only speakers are the 4 x 6's in the dash and the 6 x 9's below the rear deck. I was wondering how do u think it would sound if i kept the stock speakers where they are and put a infinity 6.5 in each door, 2 6 x 9's on top of the rear deck, and tweeters down low in the front door panels. The (4) 6.5's and the (2) 6 x 9's will be amped at slightly above the recommended power rating. Im looking to have a nice sound system to blend in with the power of my 2 15" cvrs because i want my vocals to be heard along with the bass.
