Default weak input signal to amplify

My first DIY chip amp is 5.1 channel. I have got a DVD Player having 6 channel oputput. My home-made Amp 44Watt per channel sounds good. But the Same Amp for Sub-woofer sounds very very weak. I think, My DVD Player's sub output is weak. What should I do to improve the Subwoofer Signal to amplify.

I assume that the sub output from the DVD player is not active and it seems as though you will need active equalisation.

Thank you,
i.e. Adding buffer basic circuit (NE5532), my problem would be solved? OR Active Filter would be solved this.
Please help me in detail
