So we just started doing live gigs. I purchased a Kustom 300w Profile Two system and it works beautifully regarding everything but the low-end frequency. I have two Gemini 800w GX-1500 speakers with the 15" woofers and a pre amp for them. I wanna ensure that I'm safe to run all four speakers, as I'm new to Live Sound. Thanks Guys any help ASAP is amuchly appreciated.
I'd hate for that to happen again.
