No you won't run into problems. JBL has a van with (4) A6000GTi's on (4) W15GTi (the 15's are rated 800rms and are taking well over 5KW). I've been in that van. Its here local. I used to run a W10GTi off my 601.1. All I can say is sounded **** good but I know it wanted more around 1200W.That's a JBL product IIRC....wonder who sells it.
700 watts RMS...run into the same problem as the pioneer(1000/3000).
Thanks
Why not go with the 1000watt rms sub, and keep your gains down? I am still not sure what the deal is using so much power for a speaker. I had a 10 sub in my truck and powered it with a measly 150 watts and it shook the hell out of my truck. I even put a 600 watt jbl amp to it a couple of days before I sold my truck to see if it would have mad a difference, and to tell you the truth, it was not that much louder. I guess saying I have 1500 watts is cooler than saying i have 300 watts.
