Sub woofer output and bass shaker (1 Viewer)

[SamCK]

My receiver has a single subwoofer coaxial output, but the aura base shakers have a + and - connection. I'm trying to figure out the proper wiring, ie series or parallel, but I need to figure out this problem first. ie, single coaxial cable to + and - speaker wire. Thanks.

You need to split the coax. One goes into your powered sub, the other goes into another amp then out to your bass shakers.

What are the minimum requirements for a separate amp to power just the shakers, ie the cheapest off-the-shelf amp at a local store.
