Posted November 1, 201113 yr So I am starting a new build and really cant make up my mind on the subs. Its not as much a "which sub problem" as much as it is the enclosure, I dont have experience with either so that is why Im asking for advice. Please keep in mind I have a 2003 maxima.So the dp would have to be sub up port forward with the rest of the trunk space walled off. While the 12's can be sub and port forward with the trunk walled off. My goal is spl, and I have the electrical to back either design.I know cone area is usually a good thing to go by for spl, but I really dont know how much of a difference the enclosures will make to spl or sq. Also keep in mind my current set up is 3 10's sub up port back, and I'm happy with it but want to move to 12's since 10's lower sub selection(ie no btl's).Please let me know what you think and why.

November 1, 201113 yr SPL..2 15"s subs forward. Huge aero port in the middle, also forward. Set back about 6" into the trunk. Not sealed. Tuned to around 45-55Hz.
November 1, 201113 yr Can you really fit the 21" and enclosure in your trunk?Was wondering the same...
November 1, 201113 yr Author Can you really fit the 21" and enclosure in your trunk?Its a squeeze but yes. Maximas have large trunks with a lot of weird angles, but I cut most of them out. This is why the sub would have to be up though.I believe the trunk is 15.1 cuft so I could easily make a box 9 to 10 gross. I would to utilize the spare tire well if necessary as well.

Tuned to around 45-55Hz.This is a good idea, and could be another option. The only problem I could think of is my strut towers stick out about 6"-8" from each side leaving 36" in between, though i could move the box a little farther back.

I planned on porting the box, but if you meant the trunk is there any reason why?
November 1, 201113 yr Author He means the trunkI Figured, whats the reason to not wall off the trunk? I was under the impression not walling with subs forward will add cancellation from the sound going into the trunk then back out.Also poll has been updated to add 2 15's
November 1, 201113 yr Drew knows his shit. I wouldn't be hesitant to take his advice. I have no experience with Maxima's and there trunk layout. But I would take two 15's in a optimal enclosure over a 21" thats squeezed in there. Do you have an amplifier already?
November 1, 201113 yr The setup I recommended is for SPL only. No music. Here is an example. A local friend of mine.

Do you have an amplifier already?When I said squeeze I meant to get the box into the trunk, I can make the box to recommended specs(2 15's is more cone area so im looking at that more than the 21 any way). And I'm asking for knowledge not out of hesitation, to clarify I dont think hes wrong, but I'd like to know why hes right. Also I do have an amp, aq 2200 and id be adding another for the 2 speaker set up. Edited November 1, 201113 yr by k1llj0y
November 1, 201113 yr I just want to make sure your on the same page as what Drew is suggesting.This setup is not geared for playing music, just tones, correct?
November 3, 201113 yr two 15" drivers = 353.25 sq in one 21" driver = 346.185 sq inthis is generic of course since you're going to have varying cones/surrounds on different brands, sizes, etc. but is recognized by MECA and possibly other sanctioning bodies
November 3, 201113 yr Author I just want to make sure your on the same page as what Drew is suggesting.This setup is not geared for playing music, just tones, correct?Yeah I plan to do a removable areo port so I can drop tuning for daily.two 15" drivers = 353.25 sq in one 21" driver = 346.185 sq inthis is generic of course since you're going to have varying cones/surrounds on different brands, sizes, etc. but is recognized by MECA and possibly other sanctioning bodies Its good enough for me Edited November 3, 201113 yr by k1llj0y
