Where from / how much / is it possible?
My days of loud ice are over, but i want to get use out of the 12" Vibe ported sub fairly soon for one evening. The quickest method (without changing the head unit) would probably be to take the left and right pairs for the rear speakers and wire them to a high/low convertor which i can then plug into the sub.
Its not the best, its not ideal, but it does the job for an evening.
Any advice?
