Yes, but just because they have doesn't mean you will.

Every vehicle and install is different.

This box does 142,6db on TL meter on seat. I dont mind sealing off so that air does not enter the trunk and putting the sub on the back seat for the spl competition to try do a 150db.

Paseos aren't a very loud car. Been there, done that.

1) moonroof
2) windshield slant
3) large bpillar to a pillar 52 inches if I recall correctly
4) extremely small trunk opening

looks to me like your port is too small and its not positioned properly in the box.

With that setup, with the box facing in from the trunk the port should definately be on the front with the sub.. That design would have been better in a hatchback.

You said:

Your picture is not acording to this. You should have the port at a 90 degree angle to the sub. This means you have to place it on the side of the box, not to the back, behind the sub. And yes, this type of box (sub back, port to the side) can give pretty nice results.

More like this... -
