I am looking onto getting two Lightning Audio S3.15.VC2 subwoofers but I would like to know all of the speaker's parameters before I buy them.I have already looked at the manufacture's website and they seem to skip this model. It is pretty important because I would like to build a box tuned to specific frequencies. All I know is that the speakers are dual 4 ohm voice coil which are rated at 500 watts RMS each but that is not nearly enough. Now I know that I chose Rockford Fosgate in the 'brand' under 'product's Category, but only because they didn't have what I needed to choose, and I must choose one to proceed
