Well I have not read thru all of this thread I can answer RickF's question as to the benefit of adding the new v3 amp to the EP350.
I recently had my amp replaced with the new 300w amp.( The sub input plug broke off when I was unhooking the sub-cable) Axiom looked after it on warranty and sent me a replacement amp and I was happy to see that it was the new v3.
It has made my subwoofer really wake up. It seems to have much deeper bass than it ever did before. I actually wonder if there was something wrong with the old one all along, even though I know it did work.
It does fit
