Quoted from Mr_Outlane:
I just piggy backed (soldered) off the woofer terminals in my ST pro (SAM system) and ran to floor subwoofer. Works great! Not sure why this Pinnovators board is necessary? Unless there is a reason I can't piggy back off a Spike 2 Woofer???
I plan to use this A/B switch box to connect my subwoofer to both pins when I get my JP pro. Anyone try this?

First of all, I am in no way associated with pinnovators. I’ve just used many of them.
The absolute cleanest way to go is with the pinnovators sub out kit. No soldering. No modifying your machine. Low level output. Doesn’t rob power from the cabinet woofer. Works great.
You have been connecting speaker wire to you woofer terminals and taking the high level (speaker) output from the pin to the high level inputs on your subwoofer. Works, but not ideal.
Your switcher above is a low level (RCA) a/b switcher. It’s designed for 2 low level inputs and designed to select either input A or input B. It’s not designed to mix 2 inputs into one output. It’s also not designed to merge 2 high level speaker outputs into one low level output.
Many subs have a pair of high level inputs (usually L and R). If your sub has this then you could connect both pins the same way you’ve done before from the woofer terminals. Not clean, but will work.
The cleaner way to go is to use 2 sub out kits connecting to something like the pinnovators PINsmx which allows 4 low level connections. It’s a mixer, not a switcher.
Hope this helps.
