Default 04 Altima sealing off trunk with 2 15s

this is my first build log, the car currently has the following; and installed kind of sloppy.
275 amp DC power HO Alt, KHC1400 under hood.
C&D UPS12-475-FR in back. with 1/0 to the back.
JVC Arsenal KD AHD59 Head unit.
AQ2200d running
2 AQ SDC2.5-12 in ported box tuned to 40hz
MB Quart DSC4125 powering
RF T1652-S in front, RF T1652 in rear door.
Crunch P1800.4 powering
RF T1692


For now I will be keeping the amps, I will be adding another run of 1/0 to the back for when I upgrade the sub amp and add another battery.

The new equpiment will be

2 Lanzar Opti1535Ds ( http://docs.google.com/viewer?a=v&q=...kSLS_3n322vZXw ) being run by the AQ2200d will try both 0.3ohm and 1.2ohm set up, depending on how the amp likes the 0.3ohm with box rise, probably stick with the 1.2ohm until I can get either a second AQ2200 or upgrade to a 3500.





peerless sls 8" midbass replacing the RF 6x9s in the rear deck, they will be seeing 125 watts each on a bandpass of 60-250hz at 12db/oct slope (using fmod inline filters, we'll see how they work)

Lanzar Opti65, midbass/midrange in rear doors, they will be seeing 200 watts each on a band pass of 100-1500hzat 12db/oct slope

1 set of Alpine type R comps in the front doors, seeing 125 watts each set with a HP set to 100hz.

I have 100 sq ft of deadener for the doors and rear deck, more so worried about getting rid of rattles and vibration then anything else.

I just finished up the box, it is 8 cubic ft net, 115 sq in of port, tuned to 30hz. Was designed to take up the entire opening between the cabin and the trunk for minimal foam and deadener to seal off the trunk. The box is 3/4 mdf, but the outer baffle is 3/4 birch ply. the subs weigh 63lbs a piece so thought that might be better. We'll see not like I can't pull it back out and redo it.






I will be stripping out the backseat and rear deck, then cutting the sheet metal to get the box in place between tonight and tomorrow.

my plan is to get the box in and rear deck speaker adapters and speakers in first, seal the rear deck and wire everything in the back up, then deaden and seal the door speakers. and once the wires are as they need to be seal the trunk off then either add a beauty panel or cover with a speaker grill fabric to hide everything.

some quick phone pics attached, I was just wondering how to post them in the body of the post using a link from photobucket . I will get pics of gutting and cutting as well as current and new equipment up tonight or tomorrow depending on how soon I can get them uploaded.

any suggestions welcome.

I got majority of the ideas from mistrass's build log for his altima.

I already have the equipment, time to work on it is more my rate limiting factor. Work about 60hrs a week, have a wife 2 daughters and a son due in september, so get what I can done as I can fit it in.

thanks

If interested here are some more pics of the subs,







these are the door speakers,




Last night I pulled wires, gutted the back seat and deck area and measured everything out.





I have aviator snips, a ferrous metal cutting blade for a skil saw, and metal grinders for a right angle grinder to get the sheet metal out, any other suggestions welcome but I will be doing it right when I get home. As you can see taking quite a bit out. Box dimensions are 40" wide, 18" tall and 31" deep.

put 8 gauge binding posts in the box, all 8 gauge wiring.



Also measured the usable space for making ring adapters for the peerless SLS 8" midbass in the rear deck, less room then I originally thought so the adapters will need some triming,

I rewired everything so it works, this is the car I use to drive to work and I have a 45 min drive so I need music. So here is the sloppy music.



Also have a question, can get a really good deal on #1 welding cable (Flex-elene sepcs say recommended for 300amp at 25'), can get enough to do 3+ and 3- runs for less than adding another run of 1/0 form front to back. Anyone see an issue with doing that instead?

I added lines in the pic below to show where I am cutting, it was drawn on the metal with a sharpie, but the picture is dark.




What size subs, you should be able to keep so it latch closed still. I am removing the rod latch and the string to open it since I want the trunk sealed and don't want have to pop the trunk to put the back seats down.

I should have the metal completely cut tonight and will put up pics, last night was my birthday so I didn't get to do much, still in about 15-20 min made more than half way through the cuts with aviator snips, I will use those to make all the cuts and then the angle grinder to clean them all up.


I am a copy cat though, basically stole alot of the ideas from mistrass altima build, you can see his here.

http://www.caraudio.com/forum/genera...uild-pics.html

I really like the idea of the speaker grill fabric too, you can put your seats own and no one even see the set up there, I am lazy and thinking once everything is sealed off and read to put the back seat rack back in gonna staple it right to back of the seat set up to hide everything rather than making a beauty panel and adding the speaker fabric.

another really good thing witht he altima, when you take off the rear deck there is already real sound barrier antivibration mat on the back deck, at least i had it with the bose system. And the deck holes are pretty much sealed with some vinyl stickers. Makes it easy to deaden and seal.

So I just looked at you build log, if you were putting the spy box for the 2 x12s forward facing you you wouldn't need to cut anything. Just makes some MDF or ply to frame it, then seal it butyl flash tape and deadener, rather getting foam all over.
