12" Dual 4Ω 500W RMS Subwoofer Reviews

This is a great sub with clean and clear sound. A good choice.

Use to have several of the older thunder 8000s back in the day. Now I have one of these 12 in a sealed enclosure in my g8 hooked up to my factory radio. This thing hits tight and clean, pounds more than what I was looking for! Looks of good quality an hopefully it holds up in the long run like my older mtx. Another great subwoofer by mtx.
