Yeap. You read it. I got 3 PowerBass Xtreme 15s in a large vented box. They are all dual 1 ohm, and I have them series parallel wired to 1.5 ohms. They slam. They take up more room than necessary. They shake the dirt off my truck, and causes severe roof flexing. If you want to purchase, it's gonna cost. Crazy Ralph (local dealer, and best prices) sold these subs for $349 each. The box was $400. So, add it up. Thats over $1400 worth of BANG. If sold, I want $700, obo. As for trade, I want a downfire box with 2-12s. I want 2 good quality subs. This would be a cheaper route in most cases, I'll trade, straight up. Let me know.
