IDMAX 15D2V.4 enclosure

Hi, I am currently trying to build my first enclosure instead of buyinig a pre fab box. I am looking for more sq then spl and dont know rather to go with a sealed or ported box. The subwoofer is a IDMAX 15 d2 v4 and I am installing it in a 2017 accord sport. Ive watched videos on windsid and could not figure it out. I was wondering if anybody can help me out with this build or possibly provide me a with a blueprint. I am looking to put around 750 watts to the sub. Any help is appreciated. Thank you in advance.
