I like my current setup a lot. I got a kenwood exelon (sorry if mispelled) head unit and two 6.5 kenwood exelon speakers in the door with tweeters. Its amped with a 4 channel kenwood amp. It can get loud but it starts to lose its clarity. I wish i could get more volume without losing that crystal clear sound. Also, I have NO lows or bass of any kind. Im not looking to put kingkong in my trunk but id like some form of lower notes. Most newer cars have better bass when they are stock. My dads Pre Runner has better bass. I literally have NONE lol. What form of mod would you do to accomplish these goals. Like i said i dont want king kong but id like to be able to hear it and possibly crank it up if i was showing off.

Thanks
