Hello, I thing this is the right /r/ to ask this. I have a HTiB and I want to make 2 led strips with ~6 meters blink with bass. I have done some tests with my old subwoofer (logitech z5500) and I noticed that as the bass goes deeper, I got distorsions...

I have read that we can use an amp to store energy (? :S) but it could start a fire due the heat. Can someone help me? Obviously I can use the leds directly conected to the subwoofer and dont turn the subwoofer volume to high and everything will be ok, but I really want to make something cool and safe.
Regards and thanks!

The HTiB this an Onkyo HT-S9700THX, and the subwoofer is powered directly to current, the amp just pass signals. I thing this is called a pre-amp subwoofer, correct if Im wrong please.

You can't just hook leds across the line level input of the sub or the output of the subwoofer amp inside the cabinet. You need circuit like these
