Title basicly ses it all...I was just wondering what i could possibly hit with 2 12" stage 1 RF punch subs. I also Have a A-Bahn a8002v. The subs will be running at stero mode and thats only 400 RMS. They are in a sealed, 35x15x15 box, and they are in my Chevy Blazer. Thanks for your advice. I know it wont be too much but i just want a ball park, and not have to go and get it tested cus they are pretty weak and i dont want to waiste money. So yea just a ball park DB would be cool. Thanks. Kyle
