I read thru this posting and thought it was an interesting idea. I have several of my pins running thru an external powered sub-woofer, but thought this self-contained package was a cleaner installation so i went ahead and purchased the 8" version.

I installed it on my Star Trek premium. I love the soundtrack and the sound effects are loaded with a g'bunch of bass notes. The premium already has an 8" woofer and it sounds pretty damn good already, but I wanted more.

The installation was simple and straight forward. Stern soldered the connections to the sub, so I installed spade connectors to make it a cleaner install. My 12v tap was already being used for an other mod. I used a 12v splitter connector and pinned a 3 pin power connector on the amplifier power cord. The power taps included in the kit would've worked fine, but this looked cleaner.

Everything powered up fine and I started my first game. The sub amp was at about 50%. The pin might have actually vibrated off the floor. Good lord this thing can crank out the bass. I adjusted the volume to a more reasonable level and I am absolutely loving it. The external subs on my other pins are a great addition and make for a great experience, but this self contained bass monster is something all together different. The bass is super clean and you feel it throughout the game. The closest thing I've experienced to this is TNA. The sound effects during Nero and the Vengeance modes were already my favorites, now they are simply epic.

I'm tempted to replace my external subs on my other pins with this mod. I'd do it without hesitation if I can find buyers for my external subs. I have no doubt I'll use this mod on any new pin that could use a boost.

I'd be very interested...

I've installed the backbox and sub woofer amps and speakers in my AC/DC and Stern Star Trek. I can't say enough good things about how well they sound and vast improvement over the stock setup. The closest stock set up would be TNA. If you've ever had the chance to play that pin, you know how immersive that sound system is.

I recently got my Star Trek back from a short term swap with a friend and damaged the backbox amp. The power cord to the amp got tangled in the cabinet and stress fractured the female plug on the amp when I folded the head down. Totally and completely 100% my fault. Better cable management on my part would've prevented this from ever happening. Mistake made and lesson learned.

I reached out to Dan to see if he had a spare female connector he could sell me or point me in the direction of where I could find one.

His response and level of customer support went way above and beyond anything I would ever expect or dream of receiving. I asked for an inch and he insisted on providing me a mile.

I'm back up and running again and a lifetime fan of @pinwoofer, their products and company.

Long story short; buy with confidence, the product is amazing and the customer support is off the charts.
