I tri-amp the 3 front speakers. I use a relay to protect the tweeters from transients. As long as you power down the amp about a minute before you power down the crossovers, I think you'd be ok. The outlaw amps don't seem to have on/off transients. I have a ckt I put together to sequence the power up/down sequence and watch for power fail. I suspect that the only time the relay is needed is on a power fail to keep the crossover thump from the tweeters. You can check http://www.stabie-soft.com/ht.html for a full description. If your interested, I can send you the schematics for the controller.
