Hey guys. I am looking to purchase an aftermarket sub. I want something that will hit nicely, but I do not want anything extreme, no need to rattle the car. I am looking at a 12 inch. Does the 12 inch sound good with the factory stereo system, no dsp? Or should I get 2 12 inch subs. I like the single, less space, and fits in my price range. What do you think? Thanks.
