Quoted from CoolCatPinball:I had a sub alligator clipped to my Guardians machine for 6 months or so with no issues. However, I did eventually buy and install a pinnovators board because I was concerned/curious. I am very impressed with the pinnovators product. I immediately noticed more/cleaner bass from my sub. I have since ordered 2 more for my Ripleys, and my Jurrasic. It's only $35, and makes for a safer and cleaner install. Just my 2 cents
Hello Pinside it’s Sandra from Pinnovators here 
. This is my first Pinside post ☺. lllvjr has always posted for us but I thought I’d give it a whirl.
First I wanted to say thank you to everyone who buys and enjoys our product! A lot of time and effort go into the design of each product we design and we are thankful for everyone who enjoys our products.
I wanted to say a couple of things about our sub kits that may or may not be known but I figured I’d throw it out here.
Why buy one of our sub kits?
Most importantly our subwoofer kits maintain the correct polarity of the subwoofer signal so you don’t short out the signal if you plug two machines into one subwoofer. They also Include amplifier output protection via an attenuator before going into the subwoofer.
It provides a clean plug-and-play solution for people that don’t want to have to hand-build an alligator clip solution. No need to worry about alligator clips falling off your speaker.
Our spike kits also provide stereo output so you can connect your game to an external amplifier.
Our MSPO also provides an isolated output to avoid ground loops when running two machines into one subwoofer.
Our PINsmx also provides 4 ground isolated inputs and is designed to work with our headphone kits.
Also, our pricing is competitive and includes everything you need to get the install done in 10-20 minutes.
