How Do You Run Two Subs?

[mjfoster77]

How can you run two subs in your system. Most receivers are 6.1 7.1, how do you get 6.2?

 

[mike c]

you can't actually get 6.2. but you can get two of the .1 in a 6.1 setup using a y adapter.

in short it's just a dual MONO (LFE) subwoofer setup

I tried to run dual subs today with a y adapter and my harman kardon dpr1005 after about 5 mins quit putting sound out of the sub output. Why did it do this? I had to turn it off and back on

Sounds like the sub out was overloaded somehow.

I have heard that some receivers do not output a high enough signal to be split, perhaps your sub didn't auto detect a signal after awhile and just shut itself off. Do you have it set to auto or on? I have a hard time understanding how splitting a low level connection would have any bearing on the reliability of your unit.

some subs have a lfe, or signal out option which allows for daisy chaining the subs

If you are using the subout on the reciever there is no voltage going out of it is is simply a signal. You should be able to use the spliter and not have a problem, with 2 powered subs. make sure you have the flow directions correct for your wires and splitter. there are certain ways to hook it up

simply a signal? could you clarify

IIRC, the sound and vision mag bench tested the 'maximum unclipped output' of the harman avr330 (and many other receivers) and it had 9.2 volts.

i'm thinking splitting the "signal" output only halves the "voltage" and does not actually affect the receiver.

agreed, i just wasnt sure about the no voltage comment, and wasnt sure as to the subouts actual number. The auto detect on subs wouldnt pick up the signal and the drop it would it?

i wouldn't know the first thing about these electrical thingies

i'm just parroting what I read

but with regards to selkec's problem, i'm guessing it's either a defective receiver or his subwoofers...
