my shaker 500 system in my 2005 mustang is nice but my bass is kind of weak compared to where I would like it to be. the rest of the sound is nice, not over the top loud but nice over all. so my question is how can I increase my bass and my overall sound quality to make it sound really impressive. my budget is $150-$200. I was looking at some drunk sets that are pre-made because I know little to nothing about sound set up but I would like something with some flashiness to it to make my trunk look nice if I would go that way. thanks for the help in advance.
