We've been running our own sound for the last 5 years at venues we play that don't have built in PA's. Our PA is two powered Mackie SRM450's as mains on poles to which we run a signal from a Yamaha 2x500 powered mixer and also run a powered signal to 2 12" monitor wedges. Currently running as a 5 piece. 4 vocals, drums, keys, bass, guitar, and pedal steel. We just picked up a new 1000W powered 18 Mackie sub to compliment the SRMs in hopes it would allow us to mic the bass drum and run bass thru the board as well. It has a built in Xover, so thinking it should be pretty much plug and play. Is there anything we need to watch out for or to take into consideration when setting up with the new sub? Thanks in advance.
