Signal Processor or not?

I started off with a signal converter and amp with the stock HU and some Focal components.
Since then have added an aftermarket kenwood DDX318 but I still have the processor hooked up between it and the amp.
It sounds OK but wondering if I should remove the processor and go straight to the amp.
Any benefits to this? Would it sound better without it?

 

What kind of SP and amps do you have??

I assume you're using the pre-amp out's on the HU and not the SP to be a line converter anymore??

If you're not, then pre-amp out's all the way. I have had many issues and sub-optimal sound when using certain line converters vs native out's from the HU. (Especially if your Focal drivers are on the high end side).
