I picked up a set of speakers that included a 15" passive sealed sub. The speakers turned out to be highly modded in a bad way, non original drivers...basically Frankenstein's. Money into them is nothing much so I am not too concerned. The sub however may have potential. Dual VC. I am using the plate amp output, wires off a 180 watt plate disconnected from the driver to run to this 15" sub. There are 2 -/+ inputs on the sub, I have 1 +/- coming off the plate amp.
What is the best way to hook this up to run both VCs?
