What is your issue exactly?

By scoshe converter I assume you mean a low output converter.
If so, what did you tap into for signal?

disconnect the HK subs and the small sub amp (small heatsink box connected to the factory sub enclosure).

When I was using the factory cd deck I tapped into the rear channel using a guide on this forrum.
