Hi there! Based on your question, I'd recommend looking closer at the Pioneer TS-WX300A Active Subwoofer With Amplifier And Enclosure Combo - 12 Inch 1300W, available for R3665. As an all-in-one powered sub and enclosure, it will provide loud, clean bass without needing additional amplification. The 12 inch driver with 1300W rating should give you plenty of low-end impact for your music and movies. Let me know if you have any other questions!
Based on your question, I would recommend either the Kenwood KFC-WPS1200F 12" 1400 Watts Slim Subwoofer or the Pioneer TS-WX300A Active Subwoofer With Amplifier And Enclosure Combo - 12 Inch 1300W. Both have a powerful 12" driver and built-in amplification capable of producing very loud, deep bass. The Kenwood option offers 1400 Watts in a slim package while the Pioneer is an all-in-one powered enclosure that handles the amplification and box integration for an easy plug-and-play setup. Both should provide the loud, clean lows you're looking for to really fill out your music. Let me know if you need any other details!
