If I can manage to pull money from somewhere money shouldn't be pulled, I may get another sub. I have been without a sub for year or so running the EMP's 'full range'.
When I had a sub, I used the sub cable out from the receiver to the sub with a Y adapter going to the L/R 'in' on the sub.
Are there any advantages, disadvantages to using a Y adapter? Is using the Y equivalent to bi amping?
