Lol, thanks!
Actually your purchase would depend on your budget, a good amplifier like diamond audio, soundstream ref, pioneer or kenwood would cost anywhere from 8-15k and a good sub would cost you around 10k, infinity perfect VQ or 1260w or JL12w3v2, otherwise in 3-4k budget you can get a kenwood 3010 or a pioneer 308,309, put the sub in a sealed enclosure, size specific, and it would sound nice.
