I'm going to go with a DC 2k for power I know nobody likes vs threads but I need to know lol I've had my heart set on the DD 3515 all winter now that I finally saved enough for the sub and amp I'm hesitating and thinking of going with the DC level 4 $380 off sonic probably a little cheaper from someone on the forum the DD is $719 and my local dealer seems to like the sticker price :/ unfortunately. I have family in Maine and I've read DD gives 20% off for factory direct so best I could do is $600 maybe? is the DD going to wow me that much more? The goal and SQL I will make whatever box is needed for either sub ~4 cubes
