I am wanting to upgrade from the current pioneers that I have in my Dart. It has 6x9's in the package tray and 2 3.5's in the dash. I am deciding either these http://www.classicindustries.com/mopar/parts/ma819101.html or these for kick panel speakers http://www.classicindustries.com/mopar/parts/ma1540.html Want to pick them with the most speaker options. I also need some suggestions of good 8 or 10 inch subs and a good amp I want to upgrade to speakers with a great sound quality a high volume levels and bass and treble levels.
