As a matter of fact, finished wiring up tower last night. Batteries were a little low to run a harpoon, a 1500.1 and the factory amp. After charging overnight, I had a small concert WOW.
I suspect I will have to run bass at -1 to be able to maximize full potential.
By far best setup I've run. It's rich and clean, not just loud.
I suspect there will be several garage parties! Already had morning coffee and evening suds in there!!

Thanks!!
