first off i wish you luck, hitting 160 will be very hard. prolly 90% of the people on the forum havent even heard 160, i am one of them. if my memory serves me correctly a W7 is more of an SQ woffer then pure spl, and if you really wanna hit 160 ur gunna want pure spl. With $1500 you have a lot of options. like 80 said be the 18 sx's would be a good choice. personally with your money i'd get in on the groupe buy as well but my vote would be for the MT. i'd get 2 15's with an orion 2500d on each in a ported box. id suggest a higher tuning but that doesnt always mean more db's. and as for your wiring problem...if you plan on running 4500watts you most likely wont be able to use 2 gauge wire you'd have to go with 0, along with some upgrade elec you said you had alrewady and search "The Big Three".
I'm really surprised you didnt get bashed more, i learned quick to search around a lot and not ask stupid questions cause people will just point and laugh. the search button is your best friend and a life saver. wish u the best of luck
