parallel wiring

Posts: 9
hello everyone. after careful consideration (waf), i realize that the best way to hook up the sub for my particular set up is through parallel wiring.
i have 14g in-wall wires running from my media niche to the back corner of the room where i plan to put the psw505.
i have 12g wires ready to connect to my rti38's.
do i simply just twist the the appropriate speaker and subwoofer wires together and connect them to the receiver?
come to think of it, i might have a problem fitting the twisted pairs through the binding posts of my receiver.
any suggestions or recommendations is appreciated.

If you take that route, make sure your receiver can handle the ohm droppage caused by running parallel.
I know you want to use those speaker wires that are already in the wall, but for the best sound quality, I would use a subwoofer cable from the sub out on the reciever. Then, on the receiver, set your front speakers to small, the mids on the rti38's will sound much better this way.

thanks for the suggestion. would you happen to know if they sell in-wall subwoofer cables?

This will be no problem for the amp. It is still seeing an 8 Ohm load from the rti38s, the sub is powered. The sub is just using the signal from the cable. It is the same as using a sub cable.Graham

gatemplin,
stpjcp1 wasn't talking about running his mains through the 505, but in parallel.
stpjcp1,
I've never heard of paralleling a sub, so I'll be interested in additional comments.
A sub cable beind your baseboard may be the easiest route for you.More later,

Tour2ma,
It is my understanding that he is running wires from the receiver to the 38s, and from the receiver to the sub using the speaker level inputs. This method is descibed in the polk sub manuals when you want a full signal for the mains but dont want to use the sub line out.Graham -
gotcha... my bad...More later,

STP, I've just read your post now and the first question would be why you would want to put the sub in the back corner rather than a front corner near the main speakers where it would be less likely to be heard as a separate source? If it's going to be there, then yes, you can run any coaxial cable with an RCA plug on each end behind the wall to the LFE input on the sub and likely enjoy a bit better overall sound. If you're going to use the speaker wire you already installed(note that there was no reason for 14ga; the input impedance at the sub amp is in the tens of thousands of ohms and so, essentially zero power is transmitted, just the signal. It doesn't matter how thin the speaker wire to the sub is, even 24ga would be fine)you can make the parallel connection at the receiver binding posts easier by trimming off some of the end strands of the wire to the sub so that it's thinner and can fit along with the wire to the mains. That also raises the question of why you're thinking of using 12ga for the mains; if the run is likely relatively short, such as 10 feet, there's no need for wire that thick.

large wire makes people feel better, i have 12 ga wire running to my mains on about a 15 ft wire each. the surrounds have a 50 foot piece and it is 14 ga

this past weekend, i connected my system for the very first time and i can't begin to tell you how impressed i am with the sweet sound coming from my Polks.
i have rti38s and a csi40 in front, a psw505 in the back corner, and a pioneer vsx d912k receiver. the reason for the sub placement is because i have a doorway on one side of the media niche and a fireplace on the other side of it. i still have to install two rc80is in the rear to complete my setup.
i connected the sub using the parallel wiring method described in the Polk manual. the results are amazing. i can't even tell that the sub is on because it blends so well with the front speakers. when i popped in the Saint soundtrack or LOTR 2 the bass seemed to be coming from the front speakers.
whatever type of music i played - jazz, rock, techno, rap, classical - all that came out was clean beautiful sound. my wife and ours guests were truly impressed.
overall, the polks along with the pioneer far exceeded my expectations. thanks to everyone for their help and input.
