i LOVE my 12s in a 30hz daily driver Sq box i did 142.8 on the TL so if that tells ya how loud they get (even at 30hz, AND them being 12s and not 15s) im sure that u will not be dissapointed, im givin mine like 850 watts and they take it all day... great subs in my mind they are very comparable to a W6. So id say do it man u will NOT be dissapointed.... not to mention i happen to know where u can get 2 15 RL-Ps that have never seen power... for a cut in price to save ya a little money... hit me with a pm and i can give ya details
