Lepai LP-2020 mod to include sub out
 
I have been searching but unable to find any info on a mod to include incorporation of a sub out circuit for a Lepai LP-2020 (TA2020 chip) to feed a powered subwoofer. Maybe a simple opamp circuit providing a lopass filter and buffering, tapping into the existing circuit between the volume control and the input caps. I play keyboard ocassionally for small gatherings and am presently using this amp with acceptable results. However my thinking is I could use a available sub to handle the bass which would allow me to crank down the bass being sent to my two Advent indoor/outdoor speakers thus reducing the stress on the amp and freeing more drive for the Advents. Thank you for your replies.

Hi,

Just plug in the speaker cables that are going out of the Lepai, and plug them into the SUB speaker in's. Then grab a second pair of cables and plug them into the SUB speaker out's, and run them to your Advent's.

It should work great, Let me know.
