heres an idea, if you don't want to spend a ton of money, why are you even bothering with 2 subs? why spend money on 2 junk subs when you can spend the same amount and get one quality sub. it will sound better, and if it's good it will proalby be just as loud. don't cheap out in the audio department or you won't be happy, and youlle end up going back out and spending more money anyway. get one single quality sub and one good clean amp.
