I am about to buy my first sub system. I have approx. 1000$, but the catch is, it has to be professionally installed (parents). I went to three different places and got three different types of subs options, and was wondering what the "best" choice is. please help!!!

Option 1) 2 x Memphis audio 12" 4ohm 250rms/500max ported enclosure & 600watt Memphis amp

Option 2) 2 x Alpine 15" type S 2ohm 500rms/1000max ported enclosure & 1000watt alpine amp

Option 3) 2 x Rockford Fosgate 12" P3s 2ohm 400rms/800max ported enclosed & 500 watt Rockford Fosgate amp (i think it might be a more powerful amp i don't remember)

which is the best option?

Thanks!!!
