I figure that is about how many threads there have been on the topic already. I didn't want to feel left out, so here is mine.
A few days before the BA harnesses became available I purchased a large 2x 12" round hole enclosure. The build quality is excellent, and the product arrived in good time and good condition.
When the harnesses became available. I ordered one. There was a minor problem with the order. I called Steve. He fixed the problem quickly and professionally.
I just finished installing my setup and I can't be happier. The box was a bit tricky to get into place, but didn't take too long. The harness was easy to install and worked as advertised - it would be a bargain at twice the price. I loaded the enclosure out with two Infinity Kappa 120.9w subs powered by an Infinity Kappa One amp mounted to the back of the enclosure. The bass is ridiculous, and I haven't grinned like this since I picked up my Camaro.
