I was comparing the p300-12T to the same one listed on Crutchfield and the dimensions are different. Has this been redesigned?

I think it is the same sub. Crutchfield has the wrong dimensions listed for the P300-12T. It is 25.8" wide. Amazon has the correct dimensions. I received mine the other day, and I was glad to see that Amazon had the correct dimensions. Amazon also has a much better price.

So this is my first time getting a sub and it’s all in one which is nice what do i need exactly i got the wiring kit 8 gauge and rca adapter

You need to run a solid copper ground wire, at least as thick AWG as the power wire (sounds like you’re using 8 AWG), from the sub’s ground input to your vehicle chassis. Make sure the ground point is good (use a multimeter to test). You may need to grind some paint off a metal surface to create a solid ground to the chassis. Run your power cable from the battery to the sub. Use a 75amp fuse on this run. Connect the fuse closer to the battery than the sub. Run an additional, very thin gauge wire (such as 18) to the amp turn on of the sub input. This wire controls power to the sub , so you don’t want it always on because that would drain your battery. You can hook up your car’s antenna 12v to this sub turn on, for example, since the car automatically turns off power to the antenna. The RCA you can either run from some existing speakers using a LOC or run the RCA connected directly to your head unit (stereo). In my Mustang, I used a LOC to connect the sub directly to my rear speakers in the trunk. I also wired the sub turn on wire directly to my antenna turn on wire because that is also conveniently in my trunk.
