Meh.. -5 is not so bad... It's not like you are going outside in shorts.. you have to wait till it hits ~40 before that happens.
Anyway.. I got the speakers yesterday and I got the speakers mostly installed last night. I did not get to really try them out very much. I have a 8 month old baby he was asleep. but so far... nice.. My only criticism so far of the speakers is the Hex key/ Allen wrench the speakers came with.. Total crap.. I could not the mounts on the qs4's to work till I went and got a different one.. but once I figured that out, all went very well.
