i am looking for a subwoofer(s) that will give me good sq and spl for under $200 but i am not having much luck. right now i am leaning toward an adire tempest. the question i have is if i get a really good spl woofer and replace my speakers in my car and run them off an amp should it sound pretty good? i am new to car audio and i dont know this. i know that i want something that will hit hard but i do not want it to sound distorted. what would you recommend? thanks
