Did I blow / mess up my speakers?
Hello all - I'm quite new to the speaker game and made a pretty elementary error when wiring my speakers: the red/black wires were touching at the center-channel terminal on my receiver. I'd stripped a bit too much wire and was too excited to get everything set up. As a result, my system shorted and turned off when the center was in use (this happened twice before I figured out what was wrong). Thankfully, I think the receiver fuses saved the day: everything powers on just fine (before I fixed the issue there was even a 'Check SP Wires' message on the LED display).
However, I've noticed that the center channel is pretty quiet. I'm reasonably sure the wiring is OK at this point. How can I tell if I blew the driver? Should I just increase the center volume in the receiver setup? Note that the center does work.
Perhaps this has to do with placement? I have my TV on some Ikea Expedit bookshelves and the center just inside one of the bookshelves. Is this acceptable (I'll post pictures later)?
Final questions: How much wire should I strip for the spring-clip connectors? And how can I tell if one of the wires (e.g. red/black) is not fully plugged in?
Thanks in advance for any advice.
