Wiring question : amp-sub-speakers
I am pretty new to audio world and am looking for an advice regarding wiring Denon PMA 2000 IVR integrated amp, Polk PSW 550 sub and JBL studio 530 speakers. Current wiring is, Amp to JBL using the main binding post and Amp to Sub using preout. It sounds great up to certain volume level and JBL 5" woofer starts over-excursion, aka bottoming out, at a higher volume(knob 11 o’clock & >90 decibel) to fast tempo low frequency sound like drum kicks. I am not sure how to improve this situation. Sub manual suggest "Speaker-level" connections, i.e., Amp to Sub and Sub to JBL. Is it connection issue, JBL issue, or Amp issue? Thanks in advance.

As mijostyn suggested, add a 300uF capacitor in series with your main speakers to roll off low bass at 6 dB/oct. https://www.parts-express.com/300uf-100v-electrolytic-non-polarized-crossover-capacitor--027-371 |
Or use a high pass filter in series with your main speakers to roll off low bass at 12 dB/oct. https://www.parts-express.com/100-hz-high-pass-8-ohm-crossover--266-462 |
