2 JL Audio 12W3d4's, or 1 15W3d2? Assuming the same power. I have an MTX 2300 bridged on my 2 JL 12's right now, but I am considering selling them to my friend and getting 1 15W3. I used to have a pair of 15W1's, but they were stolen. I don't have the money or room for two 15's, but I love the way they sound, my car is a 2002 Honda Civic EX. Unfortunately they aren't in a hatch like my previous cars, so what size sealed box would be best for this application?
