Default Front Firing or Side Firing port (Pictures inside)

Its a Sundown E10v3 on 600 watts. Box is 1.28 cubes net @ 30hz with a 4 inch precision port. The car is a 99 civic.

My goal is to get low. I plan to have the sub firing into the cabin with the seats up most of the time.

I was wondering if I should take the time to get custom work done to incorporate a 90 degree elbow and have the port also firing into the cabin which is location B in the picture or if it would be sufficient if I side fired with either port position A or C.

Of course I'd like to have the most SPL out of this application too. I'm just wondering if I should take the time and effort to fab a front firing port or just go the easy route and do a side firing port and either location A or C

In trunk cars I've played with forward works good if u seal it off 100% or rear firing to get better lows.

I guess I should clarify that by no means am I trying to get loud outside the car. This system is 100% for me and my passengers. I'm trying to keep all the bass contained within the car.

I do understand firing rear is best but I am trying to eliminate trunk rattle, and I'm sure this system will already be plenty loud enough for me even just facing into the cabin.

I might flip the box sideways so I can get the best of both worlds but in the end I still need to figure out port placement.

How about firing the port to the side and doing a trim panel on the back of the box sealing it from the trunk to avoid trunk rattle?

Damn thats not a bad idea actually...I might entertain it

Would you still do a side port even without the sealing back trim piece?

I've had 2 trunk cars and I liked the way they sounded when firing towards the trunk versus firing forward. One was sub and port on the same baffle and the other was port to the side. The 2 builds were like 4 years apart and different cone area so I can't really compare them to eachother as far as port location

Rear firing usually plays lower because the woofers load off the trunk and the wavelength is longer to the front of the car. You didn't say anything about eliminated trunk rattle in your first post. And you have a single 10" woofer... Your trunk should be fine

This system has yet to be built. I only have the sub at the moment. I'm in the process of getting the box built but I wanted to sort this last detail out.

I would just like to avoid rattle at all costs is all.

Deadener and spray foam to fill holes.
