I recently purchased 2 Q15's and I'm going to have them in a custom made sealed box in the back of my car. I don't know what a good amp would be for them, so I'm looking for suggestions. Thanks. Specs from my order: - 2x Q15s - Dual 2 Ohm - Cooling: Yes - P Chamfer: Yes - High QTS: Yes - Spider: Yes - I Heat Ring: Yes - Internal Lead: Yes - Rms: 1500W
