240sx box help.

[KTMrida4life 10+ year member]

Heres what I have decided so far. Im going to have someone on here help me with box design(s). Dunno who as Im new here. I am going ported. Not sure what kind of ported box, but I want to keep as much accuracy as possible. I listen to mainly rock/metal with the occasional rap here and there, but I want a box that does everything good all around. If thats possible.

I have decided on a Audiopipe AP15001 amp. 1500W rms @ 1 ohm. Cheap but the reviews for it look good. Better than the Kenwood I currently have..

Heres what I need help with. I have a tiny 2 door sports car. It is a 95 Nissan 240sx (S14). My trunk is small. I dont want to construct a box outside my trunk that will not fit, that would ****. lol

My amp is 1500W RMS. Ive looked for a single 12 (actually considered a 15) that can handle that, but I think Im leaning towards two 12s.

Theres 2 pictures of my trunk that I found online. It is a funny shape with the spare tire at the bottom, which Im removing to save weight. There is a hump at the back which is for the gas tank which my amps are sitting on right now. I will take a pic of my trunk soon and get some dimensions, but for now, search s14 trunk online and you may find more.

Im open to suggestions on how to fit 2 ported boxes big enough for 2 12s in the trunk.

You can easily fit 2 12s, 3 10s or a 15 in there. The opening is a pretty decent size too, so you won't have to build the box in there. Can your back seats fold down?

 

[KTMrida4life 10+ year member]

Yes. But like I said, theres a very large hump that only gives you about a foot of clearance between the hump in question and the bottom of the rear deck. Im taking my rear speakers out so that should vent my trunk to the cabin of the car pretty well.

I guess I'll still consider two 10s. Boxes would be a bit smaller and I would probably gain a little punch. Opinions? Im all over the place, cant make up my mind. lol

I had that same car (my wife drove it) anyway it is a weird trunk, I do not see how you would get 2 - 12's ported without using glass.

I had 4 - 8's in a sealed box and had no room left in the trunk for anything.

Yes it is a very strange trunk, thats for sure. Lots of space thats just not usable. Think one 12 in a ported box is doable?

yes 1 - 12 should fit fine. That would be around a 2.5 cube (b4 port and disp) box and that was around how big mine was.

Heres a really crappy picture of some dimensions I took in my trunk. I forgot to measure how deep it is. If I had to guess, its probably around 22-23"?

do a nice single 12. the IA flatlyne or death row would be a killer option.

 

[KTMrida4life 10+ year member]

Never heard of either of those.. I was looking at a Sundown Sa-12.

I may be able to fit two 10s.. Im cool with that too. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

both the flatlyne and death row will walk on an sa-12. especially with the power you have, unlees you plan on running the amp at 2 ohm on the sa.

i personally would not recommend someone who is getting started with the 12v industry to be running ~1500rms to a 600rms sub, the sa can take it but it has to be done right. and the few builds ive done with the ap1500 its been on a pair of sa woofers. (one was in a cavalier doing a 143 on music with a pair of 12's)

granted the incriminatiors are a little more expensive. they are also much more sub.

The Flatlyne

The Death Row

both are very well built subs. the flatlyne is a bit more sq oriented than the DR but both will perform very well.

I thought the SA 12 was closer to 1000w RMS sub? Thats what I saw on another forum anyway.

Those are expensive.. I cant do that new. Im sure you get what you pay for but its just way over budget. If I can find one used Ill consider it depending on price, but new thats a no go. I got about 150$ for a sub and I plan to hook it up at 1 ohm (full 1500W) so I want whatever is going to work the best for that price. Thanks for the suggestions, keep em coming

They are rated at 600 rms, but people put 1000 to them no problems. Running 1500 is a different story though, I would look into a different 12 if you plan on running a full 1500 watts to it.

 

[KTMrida4life 10+ year member]

I found a FI Q 15 on here, going to run it ported. Think I can make it fit? :]

 

[Phoenix Risen 10+ year member]

its going to be very tight, and may be next to impossible with out doing some glass work

just a side note, im going back to a 12 after running a few different 15s in way too many boxes. i just couldnt get the low tuning that i really wanted out of the 15 and still keep enough port area to not have any noise.

just something to think about.
