I purchased a single SR124-DVC for my RX-8 and it is still on back order. I'm looking for the most accurate bass reproduction possible and I have an Alpine V12 600W RMS at 2 ohms Mono amp (rated at 655W RMS) to push it. Right now it is on back order from the company, so I have more time to look into the box I would like to get. Right now I am set on a 1.00 cubic foot sealed box. Not wanting to build my own to get the extra .02 cubic feet to make it exactly what Polk reccomends. I just want to make sure that this is the correct size according to the manufacturer that is reccomended. I am taking the volume of the sub into account, is this correct?
