My two GK SBX-410s and 1001RB aren't giving me enough volume to fill the house in a lot of places so what next? Our PA sub farts out on the kick drum so I don't want to put any more bottom through it. It's a JBL 18" with 900 watts pushing it. Just kick and vocals going through the PA. Last night I used a Bag End 4x10 with a 900 watt power amp AND one of the GKs with the 1001RB so I had 8 tens driven by about 1400 watts! The power amp driving the Bag End was near clipping levels and the SBX was maxed out and I still wasn't loud enough. It was a big place but this is getting ridiculous. It's too loud on stage, bass is getting in my mic and there's not enough bottom out front.
We're a three-piece rock/blues/70's R&B band shlepping our own PA. Our drummer is loud (and very good so I'm not complaining). I'm wearing earplugs. I like the SBX cabs and tone I'm getting from them (tight and warm for fingerstyle, enough zing for slap) but am pushing them too hard and need more sound, especially lows out in the house.
I have a Crest 1000 watt power amp so I can run a line from the 1001RB to it and power another cab but I don't really want much more stage volume. So I'm thinking of getting a PA sub, maybe a JBL 18 to match the one the PA is running through, and putting that out front (pole mount deal to hold the other main). Or maybe getting a compressor to put between the kick and the PA would make enough room in the PA for some bass. So I'm looking for feedback on the sub and/or compressor ideas as well as other ideas.
Thanks in advance for anyone who reads this long post!

. Seems like a sub out front might be better. Not crazy about 18s though. Maybe with 8 tens it would work.
