Maybe compress a bass and a kick together try a little cut around 170-250 Hz... if u want it really heavy.. use a filter below 40 Hz then do a boost around 40 Hz .. u get a heavy phat kick, but u really need 2 choose extra carefully yer bassline so that It doesn't crash with this!!

Try Waves Rbass .. play with the parameters but the presets are preatty good...


In fact a very good kick comes alot from the mix and carefully chosen bass... which is overlooked a lot of times
