I have two 15" Power Acoustik MOFO 2 ohm Dual Voice Coil subwoofers and a brand new never used 5 Farad capacitor. I do not have an amp! The box is in rough shape but it works. I only used these subs for about 5 months, so they were just starting to sound the best when I took them out. These subs are an amazing value! With a 3000 watt max and 1700 watt rms these definitely pound. People told me they could be heard inside nearly a block away! (I had them under powered too) If interested call or text (preferably text) anytime after 4 during the week, or anytime during the weekend. I am located in Auburn NE.
