I have a ZVOX Z-Base 555, which I like very much. I recently decided that I wanted more bass so I purchased an Energy ESW-C8 (yes, it's a small sub, but that's not the point here). Alas, when I hook up the sub to the ZVOX, I get no sound whatsoever. I followed the ZVOX directions exactly -- single RCA sub cable from the sub out on the ZVOX to the sub in/line in on the Energy sub (left jack only) -- low pass control set to 55-60 Hz.
The sub powers on without problems. I had it on for about an hour straight (on, not auto) waiting to see if it would magically start working, and the rear got very hot and the unit powered off on its own. I let it cool down for a bit and turned the sub back on. When I powered it on this time, I heard a pop sound (like a power-on pop), but still nothing from my ZVOX.
Aside from any troubleshooting tips, any idea whether this issue is more likely to be from the sub or the ZVOX? Unfortunately, I have no other audio components to check and see if the sub works with anything else. Needless to say, it's all very frustrating.
Thanks for your help.
