pull the deck out and check your wiring connections between the deck and the factory harness. and you better not have a sub connected to the factory harness, other than a turn on lead, that better go straight to the battery
by fuse do you mean the DECK'S fuse(w/yellow wire) or Car's fuse?
looked up your deck...its a high power deck like mine...i have the CDA 9815...so...if you don't have any subs..you should check to make sure that the deck is wired directly to the battery...NOT spliced off the stock stereo power...This should be a YELLOW wire and it should have its own fuse (it may be wrapped in black bubble-y stuff...dunno what its called). Depending on who installed it there should also be a ground wire...this is BLACK...the has to be mounted on BARE metal somewhere on the car chassis. by bare i mean if there is paint or sth it should be sanded down to the metal. Usually this is a grounding issue. hope this kinda helps point you in the right direction.
