im looking to put subs and an amp in my car, and i am wondering what i should try to aim towards getting to get the best sound. im thinking i want one or two 10in. woofers, but i want there to be ALOT of bass. does the size of the woofer actually matter or is it the wattage that determines the sound of your system? i guess what im asking is am i going for higher wattage? or a bigger sized woofer? or what?
