subwoofer Y adapter

[nezff]

you can get a dayton audio Y adapter from parts express.
I got two for my soon to come 2 eD A2 300 subs.
I see on here there is a conflict of interest on the Y adapter. I have one right now on my Klipsch RW10d sub and YES it improves the sub dramatically. More output, and I dont think just a couple dbs. I noticed I had to turn it down alot. 4-5db down on the sub itself and 3 db down on the receiver. I can promise you that it helps to feed a mono signal into both inputs. Its not hurting anything, so why not try it. I know someone on here said that a eD tech said not to use it, but the owner or manager, Ben from eD told my on the phone that it would be a nice addititon.
