Honda's car are very reliable on gas. What kind of honda is it? I can tell you those vehilce are good for stereos too. What i like about civic are engine swapping. Anyway, you don't have to agree with me. I do like big car too but the only problem gase. It burn too much if you drive everyday. Depend on your budget on how much you want to spend on audio. 4 12" good for the bang but depend on the install. Are you lookiing for SQL or just bass bass??
