I drive a 2008 Dodge Ram quad cab and the stereo system in it doesn't really kick as much as I'd like it too. I'm looking for a little bit of thump in the bass as well as good quality all around. Up front, it'll take 2 6x9s and 2 6 1/2s in the back. I'd like to put a low profile sub under my back seat. Since I'd prefer to do the work myself to allow myself more money for parts instead of paying for labor, I need to make all the decision making as far as what parts to get on my own. What would you recommend? I have about a $1000 budget for everything, with a little bit of flex.
