Magnum Cum Louder is the fourth studio album by Australian rock group Hoodoo Gurus. The album was produced by the group, and released in Australia in May 1989 and peaked at number 13. Faulkner later said, "We produced the record ourselves for our own morale, if nothing else. We had been through a very rough period with six months of inactivity from a lawsuit to get free of our old contract. Rather than even telling the record company what we were recording we let them hear it after it was all finished, and luckily they liked it! We would have been in deep trouble otherwise."
