Tuning question

[DBz]

Going to put 2 Audioque HDC3 15's , my back seats in my civic are removed, so i'll be putting the box in the back seat (level with the entrance of the trunk), I was just putting some thoughts together, and was wondering if a setup like this would work. Having three 6" aeroports going into the trunk from the back seat cabin where the box is. This is daily driver, not trying for spl or anything, I just want really low lows, I listen mostly to C&S and slowed down stuff. My question is, what should the length of the ports be? I had em on google sketchup at like 16 inches, I've never tuned a box before so i'm new to all this, does the length of the port change the tuning frequency I want? Any advice would be great, thanks.

In a trunk you will lose a ton of sound by doing that. For that setup you want subs and port forward if possible space wise, I think it is? Or subs forward port up or port forward subs up would also work better then what you have there atleast. As for port length we would need exact box dimensions to help. yes port length and how many ports are what create your tuning.

Yeah I just wanted to throw it out there, lol. Ok I have another question, would it hit harder if I had the 2 15s in the trunk, slot port down the middle, and sealed around the edges (seal trunk from cabin), OR, seal the trunk and have the box (subs up, port up) sit in my backseat?

idk if u wanna face the ports into the trunk. id face them at the back window maybe and seal the trunk off from the cabin. and as far as tuning download this. box calculator put in specs and play with port size and length till your happy. jusy make sure u have the correct port area. it will tell u what u need in the program. and for C&S music id say tune to about 29hz

Two 15's are "doable" in a trunk but not easy to actually do right space wise. If you're still new to the big boy audio world I would say do two 12's or 10's in the trunk. And just my opinion from others. I wouldn't recommend the HDCs if all you plan on listening to is chopped and screwed. They do hit lows ok but they don't really do well tuned low.

I mean I want to be able to play all kinds of music, but I want low lows, so I figure i'll have to tune it kinda low. I have 2 L5 12's in right now, and they hit nice. But I wanna move on up to something louder and powerful.

Even the 12 inch XL's?

If you wanna play lots of C&S run 2 or even 1 6" aeroport.

My friend was doing some ridiculous numbers at like 28hz fooling around with 2x DD 9515 in a 6 cube box with 1 6" aero.

That design looks like he one fritos is using in his trunk car with a sngle 18" and 2 8" aeroports, he has sub up/ports to the back and he scores and sound very loud, check him out...
