Boss Audio *****.... not the actual product itself because I have no experience with it (glad for that) but as a company they are shady, corner-cutting, and just trying to turn a small profit by selling (for cheap) low-end products that were made for even cheaper. Their customer service is horrible (I have contacted them before) -- it would be better if it were nonexistent. And good luck extricating any type of T/S specs or honest ratings out of them.
Doing things right the first time doesn't mean you have to spend an arm and a leg. Take these guys' advice, and take your time. Good luck with your setup, hope it ends up sounding great!
