I have purchased a Diamond D9 12 inch dual voice coil sub. This will be a single sub in a sealed box in a SUV. Its RMS is 800 with a peak of 1600. I was questioning how much wattage I need to run this sub? I want to ensure I purchase an amp powerful enough to run it without clipping issues. I am more interested in sound quality than SPL. I plan to purchase a class 'D' type mono amplifier. There are many out there, but quite frankly I don't know what would be best suited for this sub. Any input would be appreciated! //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
