depends more on you actually what kinda of bass do you like? do you like clean tight bass or do you like loud more of a boom bass, if you went with audiobahn then you probably dont care to much for sound quality! audiobahn is more for loudness not sound quality sorry!!! thats why they you such high amperage on the equiptment for the most part. Your best bet is to go with 10s in a honda civic that will give you more of a cleaner tighter bass 12s are two much in a civic that you will have to rattle proof you car so to speak. if you want pm me or email me at dspencer24@yahoo.com and i will tell you more and ill be more specific!!!
