FedEx actually still messed up the address after I had corrected it twice. I even went to the facility to pick up my package, which then wasn't there as it's all ready to be delivered to me Monday.
Guess it serves me right for trying to change it last minute.
As for alternatives at least for using the sub this weekend, what is my best option that won't require a ton of calibration later:
-speaker wire or RCA cable?
And also, will component video cable work or just standard RCA cables? I feel like the component cables I have are more shielded, but don't want to connect anything that could ultimately be damaging.
