I have to 12 inch pioneer subs in a bandpass box. Now the bass is nice for what I'm feeding them. They're 800 rms for both and I'm giving them 500 watts so they are underpowered. I was thinking of getting a kicker zx750 to add some more power to get their full potential until I save up for the new subs that I want. I'm thinking about getting 2 12inch kicker cvx and another zx750. Anyone have a set up close to this or have kicker cvx subs. I've installed them in a few cars along with other kicker products. I love how kicker gives you good bump for your buck. Let me know wat you think

 

Are you just guessing on how many dbs you think your hitting? I don't think you know what it takes to hit those levels of dbs. I have a friend and he had a 15 inch dd audio and 2 15inch rockford fostgate t2s (that translates to about 4000 watts rms) and he bo 1just hit 150 dbs. And I know about enclosures. I always build enclosures to factory specs. What kind of box do you have your subs? Pics would be cool
