Port forward instead of toward tailgate?

[Pioneerchuck]

The question is, has anyone ever done port forward towards the cabin instead of port towards the tailgate in a non-walled SUV? I have a suburban and the tailgate caught absolute hell on just the 2 18s and now that Im upgrading to 4 Im looking at other options. I refuse to wall it off (anyone can get loud off of a wall). I will be swapping over to the 00-06 2nd row captain chairs and the port will be basically in the "tunnel" area. I assume the tailgate acts as a loading wall, so if I flip the box around Ill lose pressure with no loading wall? Idk, someone help.

I've tried it before in my old explorer. Low power, 1200w, it didn't sound louder or quieter, but it sounded different. I didn't care for it.

Port back will be louder. Port forward will have some cancellation with the wave that reflects off the back wall.

The goal is to have the port firing near the perimeter of the vehicle, the farther from the perimeter it is the more likely you are to get reflections that will cause cancellation a certain frequencies. If you aren't going to fire the port back, I'd suggest firing it up and have the port at the very back of the box.

Damn...That kinda kills me a little bit. Lol any ideas on how to tighten up the tailgates on box body chevys??

Maybe you could adjust the latch?

I had a thread about this not very long ago, someone suggested adjusting the latch but I took out my hook and loop thing and there is no adjustment. My hatch rattles also and it fucking sucks, I have shit tons of sound deadener but it doesn't prevent the hatch rattle. I dont wanna wall but it's the only way to get rid of hatch rattle.

I am trying to figure out a way to anchor the hatch to the vehicle but still be able to open it when need be, until then it's ratchet strap, LOL!

I feel your pain........

Maybe a loading wall could be built onto the back of the box where the port is? Three sides and a bottom with the top open like an extension to the box. The wall part could be made as tall as you want maybe 2x box height. Maybe this would give it something solid to reflect off of and take the load off the gate.

you could do that but the hatch is going to rattle either way. think about how everything else vibrates that is not a loading wall for the port. it's just inevitable for it to vibrate and rattle due to the shared air space. making your own loading wall in between the port and the hatch may soften the blow some, but it won't eliminate it, nor do i think it will be very effective at all.

Yeah its the shared air space that is the problem. That's why walls work.

I have seen people modify the weather stripping on their side doors to eliminate wind noise maybe it would help tighten up the back gate. What they would do is remove the weather strip and slide a 1/2 inch or whatever size foam cord into the open end of the weather strip and work it down the whole length. Then reinstall and have a tight door.
