1) My amps work fine un-strapped but go into protection when strapped and/or my amps are stuck in protection. - 3/8/07 I have had three customers with this complaint. All three of them replaced their RCA cables to remedy the problem. Some model Stinger and Memphis RCA cables will NOT work with the SAZ-1500D, *especially* for the jumper RCA from master to slave based on the feedback I have received. Be advised... this should be the FIRST thing you check if your strapped pair is going into protect
