depends on what ohm load you need the power at and how much power. you do know hifonics overrates thier amps so a '1200 watt' hifonic amp will probably do about 1000wrms, give or take some.
well in youve got hte money for hifonics or audiobahn....you shoudl totally look into the 2007 series rockford fosgate series subs...their badd ace... i probably only spent like about $1000 and got rockford...subs, amp, wireing, and tons of window shattering power....and actually i cracked the window in my g/f's s-10 with them..lol...anyways if your all for those brands go with the hi- fonics...peace man
Yeah it was a joke....but you can scream at the top of your lungs and not hear anything....its like pure bass....but my neighbor has 2 13w7's that did crack the back window in his hatchback mustang...oh yeah back to this post....try lookin at some rockfords..
