I have a 589W Sony home theater system and been wanting to add the aura bass shakers to them. I know my receiver doesn't have enough power and I want to purchase an amp for the bass shakers alone. My receiver is so limited on outputs and it doesn't even have an RCA output. It just has an HDMI, headphone jack, and the speaker wire output. Can anyone figure out a way to connect my receiver to an amplifier? I was thinking about getting a speaker wire to RCA adapter and connecting the RCA adapter end to the amplifier, and then from the amp, connect my bass shakers. Can anyone tell me if this would work?
