i have a solo baric L7 and its powered by 1200 kx kicker puts out 1500 but anyways my bass is loud on the big notes on songs and when the beat changes its not so loud like the highs sound good but the mids u cant really hear and not that loud at all is it cuz its just a 15 .....would 2 12 L7's do the same if i powered them with my kx 1200 amp or would it hit harder and sound louder?
