MMG sub hookup....

@batman
My sub only has line ins

And speaker input
And speaker output.

@batmanI could split pre and run to sub..
And a run to amp then...

If you want to high pass to the speakers you can use this HSU high pass filter. If you want to run the speakers full range you will need Y adapters from preamp into amp and into the subwoofer!
I use this to high pass to main speakers!
You will need 2 pairs of Y adapters to do any of these choices!

Thx.   Why do. You prefer high pass?
Instead of full range..

I assume using speaker speaker out sub uses high pass frim sub no?

I’ve tried it both ways and I prefer using high pass to the speakers. Some prefer running full range. It all depends on the speakers that you are using. What sub are you using? I doubt that it has a high pass filter ! BTW, if you decide to go with the line level option these y adapters are what I use!
