I far prefer the DD2500's sound to the Kicker CVX, and yes in the right install you will get better performance out of the DD2515.
As far as price. Like you said, you can get the DD2515 new for ~$300...compare that to the CVX15's 'in-shop' price of around $425.
Better sub, better performance, better price, USA built, reconeable.
Just my $0.02, bu try a DD2515 on the new DD CM1 Yes, I may be alittle bias...I'm a DD Dealer. But here at the shop we do both new and used audio. I build as many boxes for Kicker subs as I do DD, hands down my customers prefer the 2500's sound to the CVX's. Unless they are on Kickers nutz, then there is just on helping them.
Depending on the sound you want, that DD2515 will sound good in either a ported or 4th-order. The 4th-order would be amazingly tight and punchy w/ great range (when designed properly).
Get rid of that amp kit right away and get a brand name one.... almost all of those off brand kits lie about the actual size of the wire and there is no way to know, and believe me you DO NOT want to run a wire that is not the proper gauge.
lol i think that wire kit is crap i got some cheap wire one time.... when it came in the mail and i looked and it i didn't even waste my time to put it in
Those CVR's will be very loud in that blazer. It really doesn't take too much to get good levels in an SUV. I have thrown some single 10" boxes (ID, AA, Fi) in my Pathfinder just to test and I am always surprised by the output. It helps to think of it as a real small room, with the added advantage (and disadvantage) of acting as a cabinet. The 15's won't have much SQ but if what you are looking for is some thump, you got that.
but on that amp kit i just bought it cause i just would have though it would be good, being the kx1200 reqires name brand 4guage, so i just bought cheap brand 0 guage, but if thats really not enough ill by better, i dont want amp problems
