I've been back in forth 100 times over, and I've made my decision. After getting my Alpine head unit I have been determined to finish my system. I have decided to run one AQHDC318 powered by an AQ2200D. Should sound good. I love bass but, I'm pretty handy at setting systems up to where the mids and highs can still be heard crystal clear. I listen to all music from reagee to country to metal to rap and R&B. So, I think this will help feed my love for bass after doing some research. But, first step 2 or 3 layers of Dynamat! Yay FUN FUN!!! :rockon:
