freestyle350

im getting a fully loaded fi bl 12" and i planned on getting a hifonics brutus 1600, or if i get a little more money im going to get the Rockford fosgate t-1500. i dont know shit about wiring amps and. i know almost everything about the basics of car audio. but i was wonder how would i run that Bl 12" at 1 ohm. my friend said i would need a second sub to run the amp at 1 ohm. but he confused me because the amp is a mono channel amp so i dont need to add another sub right? both those amps can be at 1 ohm stable. how do you change (ohm's) ?

i have wired amps before so i know all about that shit. and thanks for the dual 2 ohm comment, i will do that. i also want to know what you guys think about the RF t1500 amp? i know that hifonics will do just fine. but do you think that fully loaded bl 12' would take that RF 1500 at 1 ohm? because thats alot of watts and its a better sounding amp, so do you think the sub can take the power and do you think its worth the money over the hifonics?
