No, wire is based purely on size. That is why they suggest buying a larger gauge if you go with CCA rather than OFC. OP please just buy welding cable. You will will be much happier

I'm with you on wanting that logo. On the warden I don't have one because it fell off but the magnet does enough justice... To be honest, if you're like me you will eventually upgrade anyways. Why not get what you really want the first time? Just my .02 Get the DP and be happy. If that amp does what it says it does ( idk much about Helix ) you could put too much stress on the DR. The DP will love it in the proper enclose and you will be very satisfied.

I started my IA journey with an 18 DR and upgraded to a 21 DP. Though the DP may be more SPL oriented it performs very well musically IMO. You will not be dissapointed. I now have a 21 Warden and could not be more pleased with IA in general. Really just depends on how much you are willing to spend if you ask me

Yea it depends on how much material needs to come off. If it's quite a bit, I would suggest a sander or as previously suggested a router. Hand sanding may take a while

I have a 98 Cherokee Limited with a 21" IA Warden. And if i were to give any advice I would suggest doing sub up, port up instead of the traditional sub up port back that most SUV's use. This will help get rid of the vibration of the rear hatch and lock mechanism which is inevitable and incredibly annoying. Sound deadening is highly suggested as well considering the whole truck is made of sheet metal and is prone to vibration. Good luck with your build

Mine was all wrinkly in the middle. I will try a "heat gun and elbow grease" to flatten it out

The more information the better. I would love to help, but I don't know anything about this setup, and your description is pretty vague. Try to be a little more descriptive and you will probably receive better answers. Good luck!

Doing the big three is always a good thing. It helps keep components that are part of your vehicle and aftermarket more safe by helping with voltage drop thus decreasing current draw. I would do it. It is a very affordable upgrade. Since you already have to wire up the amps, just buy a little extra wire and some terminals and take the extra time to make the improvement right away. You will be happy you did later on

Expanding foam between trunk layers maybe?

100% correct. Every part inside the amp has a tolerance. If you measure the resistance of a 20k Ohm resistor, it generally won't be exactly 20k Ohm. The nominal impedance is 20k Ohm, but the measured may be 19.87k Ohm. These tolerances add up when you have many parts. Theres where your differences come into play.

Here is the model you will need I believe: http://www.suspensionconnection.com/cgi-bin/suscon/scan/fi=products/st=db/co=1/sf=category/se=Air%20Spring%20Kits/op=eq/nu=0/sf=veh_make/se=Ford/op=eq/nu=0/sf=model/se=Mustang/op=eq/nu=0/ml=25/tf=category/to=x/tf=veh_make/to=x/tf=model/to=x/tf=description/to=r.html Lifetime warranty also

I have air lift ride control on my Jeep and it's awesome. They don't leak at all, and deflate rate is super fast. Does make your ride a little more "spongey" though. At least it did on the Jeep. I would highly suggest it as a suspension upgrade. http://www.suspensionconnection.com/cgi-bin/suscon/air_lift_suspension.html?gclid=CKn63oehma8CFSQCQAodj0i61g This is the cheapest site I found.

I'm trying to buy the other warden from Mr. Bojangles and I have a Jeep Cherokee which has very similar dimensions to your Trailblazer (43 X 22 X 22). I am tuned in

For the price and durability, you can't beat welding cable
