i had a w6 12 in my rx-7 with a 1000 watt kenwood amp it hit hard but when they stold the sub i bought a L7 12 kicker----to me the kicker has a better sound to it......also you really feel it in the chest if you got a hatch or suv.....people think i have 3 12's or 2 12's in my trunk but i laught and say nope just one 12(ported box of course) go to a sterio shop and ask if you can hear one then see what you like better.
