Never Heard of MA

Ok call me a nOOb, I have been in stereo installations since the 70's ( you guessed it, I used Home speakers and manufactured my own amplifiers to drive em in my car...but in the last 15 years I have been out of the game..as a matter of fact, the owner of the "WICKEDEST SUB" title when I quit was Pyle.  Ok now that I have dated myself, I need to know if  MA1500XL  subs are worth gettin? Or am I just waisting my money.  I want pounding bass.  Nuff said.  I was hoping 2 of these bad boys with a 1800 watt amp would do the trick...any Ideas?

Thanks for the site
