I like putting some saturation on my bass drops/808s and have them duck the whole fucking mix like 24dbfs ala Devin style, sounds hilarious.:Spin:
Seriously though, you could try putting your whole mix through a bus and automate a hipass on the bus where the 808 kicks in. I prefer just turning the volume down, you'll probably need less volume on your 808 than you think since shit gets crazy come mastering, try putting a mastering chain in there just for loudness and see what happens.
