I have been looking into installing bass shakers onto my couch and recliner. I was planing on running an external amp to power the shakers. The issue I'm running into is that everything I'm finding about hooking up the second amp to my current surround sound set is that I need to connect to my line out rca jacks... Which I dont have. I have a samsung bluray/home theater system, all the speakers and sub I currently have connect to the unit using just speaker wires. I tried to research a hi to low converter like I have use on car audio equipment in the past but have had no luck. Im looking for the easiest way to go about this, I thought maybe using the line out rca jacks from the tv to run to the amp, but I'm not sure if this could cause any issues or have a slight delay between my current sub and the shaker. Please help.
