I heard ONE 10 on the weekend, thanks to Tom and Ryan, and they sound AWESOME, I would go with the 4 12d2's like fowler suggested.Those would definately kick your ass
Thanks for the help I apreciate it. I had a feeling my amp was to strong for only 2 of those subs. fowler u are talking bout the US 2000x model that makes it power at 4ohms. Guys one more question what size box should I put each 12d4's in. I will run them in a seal box.
