Purchased this as I was looking for a while myself but thought it would be easier buying a package. The Juice js 12 speaker came with no screws to screw it to the sub box (didn't say anything on the website that I would have to provide screws) the speaker had different terminals to connect speaker to the box terminals so had to adapt them. The excalibur 600.2 amplifier is quite dissapointing to say the least, it has a full crossover but only 3 settings on the bass and treble rather than a full range. Would like to send back but I've already screwed the amplifier to the sub box so will sell on as soon as I can. Won't be ordering anything from them again, lesson learned
