HI everyone,
I am planning to buy a sub for my Car. I think I am going with the Pioneer TS-W311D4. I am also going with the Pioneer GM-D8601 for the Amp set to 400W RMS. I am building my own box I need help designing it. In my vehicle I am willing to give this dimension which is 18"*15"*13" W*H*D. The sub needs around 1.5 cu.ft I will also use a Slot for the port. Now my concerns are what tuning frequency should I tune it to and what size should the port be. I attached a picture with the subs specifications.
