Not a bad system at all, easy to install and wire in. Comes with 1 in-line fuse 20A. I however wasn’t a fan of the hose it came with. I opted for aftermarket hose, for an additional $15.Again definitely worth it, I mounted under the hood in the motor bay, and it’s still louder than hell. Thinking about a second bank of 4, just to make ‘em jump higher! Haha
