Where can i find good Sound EFX?

[MarshColin]

Sup? Im looking for some high quality sound effects of explosions/bombs/crashes for transitioning songs on a cd. Something similiar to what E-A Ski used on his Past & Present mixtape. Does anybody know where i could find some or does anybody have some?

I tried all the stuff that i found on google and they were low quality and shitty. Any help would be greatly appreciated, thanks ahead of time.
