When hooking up psw250 as second sub, I want to have it slightly behind my couch. After daisy chaining off of the 1st one, which is up front by the monitor, I run an AR 25ft. omnidirectional subwoofer cable to the rear(about 10 ft.)
The problemo is that this loud HUM begins when I plug it all in.
I initially thought electrical outlet, so I moved it to another spot & other outlet-still humming.
I tried hooking up the sub up front on the other side of the other one, using a shorter patch cable and NO hum.
Has anyone had problems with running there subs over some length of distance?
Also, I thought that the AR sub cable was pretty decent,
could it be that I need to dump a lot of money& how much? into better sub cable?
