You want a little bass here's what you do get one of those 5gallon paint buckets and put the top back on it. Strap it down to the back seat and run any size wire to it that you want, it doesn't even have to be hooked up to anything. Next get yourself a set of drum sticks, and crank your music as loud as you want. Now everytime there should be a bassline in the song you are listening to hit that bitch as hard as you can...Hell if you want to change the bassline hit that bitch again. Enjoy.
