Which way to face subs in trunk


Recommended Posts

Sub and port rear. I heard sub up in a trunk isnt good but personally, I've never done it like that.

Sub up in a trunk work great.

there is no such thing as the perfect way to face subs in a trunk car, because every car is different. some cars like sub and port back others like them to the front. while others like subs up port back or port to the side. you just have to test your car.

True, I agree with that. However, I how to say something when someone said subs up isn't good.

Yea I really liked how my sub up port back sounded with an 18. May have to do subs up port back again because I can only go 36" wide and I will have 2 15" plus 2 6" round ports so I dont think that they will fit all goin towards the back. If I could make it look like I0:0I, then I would but I dont think there is enough room. Might have to either try some 4" pvc or face the subs up. any ideas as to how this could work better?

if ur worried about the room width wise u could do a slot port across the rear bottom of the box.

maybe 45 the top rear of the box above the port to help air flow. (i mean 45ing the actual box, not an internal brace)

You could always go subs back, and ports up through the holes where your rear deck speakers are. Then you have it ported through the rear deck without cutting it up.

The port along the bottom is a pretty good idea but I only have 18" high so the port would be pretty skinny. Porting it through the rear deck speakers is a good idea tho. If I did this idea wouldn't it be better to face them forward rather than towards the back? keep the options comin =)

On my car I have the subs toward the cabin sealed off from the trunk, it is about 4 inches from the seat at the top and about 7 at the bottom, and even when I put the seats up it still pounds maybe only about .5 to 1 db loss on the ear-o-meter. Though it would probably be a bitch to seal it off from the trunk since your seats dont fold down, also I have ran subs up port up, and subs back port back, with the same box before I sealed it from the trunk, and I couldnt tell much if any difference in my car, but I did notice an increase once I sealed it from the trunk.
