The only possible location for my subwoofer is going to require about 35 ft. of cable from the receiver. The line out at the receiver and line in at the sub are both RCA jacks. It seems like 25 ft. is the longest commonly available patch cable. Right now, I'm thinking about piecing 2 cables together, either M-M to M-F, or M-M to M-M with a female splice connector. I'm worried about signal loss from using this jury-rigged set up. Does anyone know of a source for reasonably priced good quality cables long enough to reach? Is the spliced together arrangement going to cause enough signal degradation to worry about? Is there a better way than RCA cable, like some other type with adapters to fit the RCA jacks? Sorry, this should be posted in the wiring forum.
