I'm going to quadruple this setup in a few months, but I pulled the trigger and bought one so I could do some testing. Not just on the sub, but I have alts that I like to test in-vehicle, and I can move 1 18 that can handle a ton of power around from vehicle to vehicle pretty easy. This temporary setup is 1 18 TSNS in 5ft net @ 35Hz. It's 70sq of port and kerfed. Amp is an American Bass 1000.1 @ 4 ohms with 3 D3100s and 1 240a alternator. Having owned numerous beefy subs I will say the weight and size of the motor on this thing makes it the most impressive looking. 102 lb ship weight The sub has direct 8g leads, using Raptor wire. The Raptor is on the left, some scrap "Amp King" stuff I've had for years and got for free on the right. And the test box: And a short vid. This is with the amp set to keep above 13v with just 1 alternator.
I'll post a review a bit later on this evening, but I'm pretty impressed with it. There are a lot of things that I would have done differently if I wanted to spend the money, but this is a cheap test box that will fit my needs and costs very little to build.
