I ordered a SVS 16-46PC (self powered) sub yesterday, but after thinking about my wiring route, am wondering if I should have went with the Sampson Amp. I'm going to have to run about 30 feet of wire to get from my stereo to the corner that I have to place the sub in. (I'm very limited on my placement options) I was assured by the great guys at SVS that it's okay to run a low voltage RCA-type cable that far and I'm sure that's right. Well, after thinking about placement, it's come to my attention that I'm going to have to run the wire down through the wall along the same path as a 110 volt power cable. My question is: Would I be less likely to get noticeable bleed through if I were running speaker wire already powered from an external amp than if I run the low voltage wire and to the sub and then have it amplified? If that is worded crazy, let me put it this way, Considering my wire routing, should I call up Tom and have him ship me a external powered sub along with the Sampson amp instead of the PC sub? If you have any other thoughts about the pros and cons of going with an external vs. self powered sub, I'd appreciate that too. ----- But hurry, they'll probably ship out tomorrow or the next day! Oh, one more thing.. Is the 45-day satisfaction good for the amps that they sell as well? Thanks guys!
