rebuilding a setup for a single cab truck

[cmw5e]

i used to have a pioneer touchscreen, alpine type r 5x7's, an old us amps 1500 watt amp, and 2 12" RE se's in a 2001 single cab f-150. ive sold everything and wanting to do a completely new setup. for the cd player im just going to go with a cheap functional pioneer
im open on suggestions for 5x7's . . . . 40 - 100 a pair
for the amp im either going with a hifonics glx 1000.1 or 1400.1 depending on sub setup
now for the subs. . . im not sure what i wanna go with. maybe 2 10's ported or maybe try to throw some 8's back there and port them. i am a fan of the RE subs but im willing to try anything. any suggestions would be great, thanks

i have been looking into the RE REX'S, thinking about maybe doing 4 8's. anyone ever used these? i know theyre the bottom line model so idk. or if i was going to go with 4 8's whats a good setup
