Hello pr7met7me,

Assuming that the "old sony box" has 2 chambers with at least 1 cu/ft of internal volume each, there should be no problem running the Kickers. The CVR's are dual voice coils and come in either 2 ohm or 4 ohm versions. The coils are wired together either in parallel or in series and then wired to the box terminals.

You did not specify what make and model of amp that you intend to use. The amp will dictate how the sub voice coils are wired. You do not want to go below the minimum load that your amp is capable of supporting. If your subs are the 2 ohm version, you wire the dvc's in parallel and then parallel both subs to the amp, your final load to the amp will be 0.5 ohm and there are not many amps stable at that low of an impedance.

The terminals with the white dots are for the first voice coil. The terminals with solid-red and solid-black markings are for the 2nd voice coil. In a parallel setup, you would wire the white-dot positive and the solid-red terminals to the box internal positive and the white dot negative and solid-black to the box internal negative. In a series setup, you would run a jumper from the white dot negative to the solid-red and then connect the remaining terminals to the box terminals.

Hope this helps.
