Ok guys ive only been in the game for a few months and i need a little advice. I have 2 15inch L7s and 2 ZX 750.1s. It bangs vary hard but i want somthing with a little better SQ. I am ordering a pair of Massive audio CWs. My question is should i get 2 12s or 2 15s? I will be using the same amps and the specs are the same for the 12s and 15s (1200 watt max 600 RMS) I like tight accurate bass. In general i have heard that 12s sound tighter than the more sloopy 15s. What do you guys think? If it matters this setup will be going in a Honda Element. I will be building a ported box for the new subs. Any help is greatly appreciated.
