You can have sub up port back in a trunk but it tends to vibrate the trunk lid alot.

If you have fold down seats, then sub front port to the side tends to a be louder combination.

Sub front, port front works well, with very little vibration in the trunk as long the seats are folded down.

Box carpet go here Crutchfield Canada

i can see how it tends to vibrate the trunk lid haha. But my main question is that will it have issues unloading at the port? been reading up alot on this

and for crutchfield, i cant really order online only 1 and dont have a credit card yet. But thanks for the suggestion!

Should'nt have unloading issues at the port. If you have a sketch, can post it so I can see the box?

Dont know anyone locally that sells box carpet mann, some one else may chime in on that.

Go to the flea market( ones that have car audio vendors) they usually have the carpet for around 5$/meter

That sketch is fine you wont have unloading issues, also, sub front, port front will be better, with sub as close to the port, that way you will be firing into the cabin.
