Was thinking about redoing my sub system, but decided to increase the wattage to some of my subs. I was underpowering my 18" REXXX and my 18" Maelstrom-X sub. Bought a Crest Pro9200. Will run it bridged to the REXXX and will put the Maelstrom-X on a NU6000 by itself. Will be a huge increase in wattage to the REXXX and doubling the wattage to the Maelstrom. Have changed out one of my 20 amp circuits to a 30 amp circuit. Several of the 20 amp circuits were already wired using 10-2 with ground, so simple matter of changing breaker and installing NEMA L5-30R receptacle. Have a 30 amp relay switch to build, so that new circuit can be powered on by my Furman sequencer.
