The MC cartridge phono amp/or step-up is required whether you do anything with a subwoofer or not.
You are not doing justice to your system by using such a low gain on the phono.
Some people prefer electronic phono "head amplifiers" to provide the added gain. Some people prefer using a step-up transformer to do it.
Personally, I prefer the step-up transformer, as I think it provides a better load for the cartridge to drive. In any case you'll need at least a 20db gain increase.
Some options might be:
Bent Audio Mu step-up transformers - ~$800
K&K Lundahl step-up transformers - ~$250-$300
Denon Head amp (used) - perhaps around $100
Of course there are other options, those are just a few.
