The reason I am asking is because that's the amp my subwoofers have. I was checking out the price of these amps and they're up there. I just wanted to get an idea how much my subs cost to manufacture and the parts that where used on it are of good-highest quality. I know the driver and the passive radiator used in them are around $600.--. Are there better plate amps available or is this one of the top ones. I am trying to figure out production cost on my subs. Both build in mirrow image cost me $3000.00, I guess that's a fair price. They do intergrate.
