I was messing around with my sub and wondered if it was worth it to split my incoming sub cable and feed it to the right and left inputs. WOW is all I have to say. It's like I have a new sub. My 2.3 usually will not wake up until the volume is in the low 50s. Well, I hd it in the low 70s and it fired right up. I now have to re-tune my system because the bass is too much.. I was thinking about upgrading but after this performance, I feel like I already have a new and more powerful sub. The splitter only cost me three bucks and I am satisfied.
