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. AC/DC deserves to have a sound system to elevate the music to concert quality.

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.
