k i just recently put in 2 12" ma audio XL's but they arent playing the bass lines of songs too well. i listen to mostly hard rock/metal. ive got 4 6.5" alpine full ranges (not sure of the model) and they kinda distort if i put too much low freq. through em.
i want something that will carry the bass line well. my bro has a pair of 6x9's in his trunk and first time i heard em i thought they were small subs! but i was wondering if midbass woofers would be better for my situation? and would THESE woofers need any kind of airspace to push or not?
