Quoted from kermit24:
Nope. The “line out” is not a 3.5 jack on Spike 2. It’s a pinout on the board.
Pinovators sub out board. This creates at 3.5 jack to go to a subwoofer. $40 I think.
Stern Spike 2 headphone kit. This gives you external volume control for speakers and / or headphones including a 3.5mm jack and knob at the coin door. Adjustable in settings what the knob controls (headphones, speakers or both) I have this and it works very well. $99. I think this may be on backorder
What if I want to do both? Can I just buy the Stern and add the sub out jack from there? Basically I want to add a sub AND I want to have a headphone hookup when I want it quieter.
I have a feeling I’m gonna end up buying the Stern kit for the headphones and use a line out converter off the bottom speaker for the sub like I did with my Getaway.
