Do L7's sound good sealed? I don't think I'll have enough room to run 2 15"s ported... Sealed though //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif I'm sure I can.

I think you could. i'm not exactly sure how the shape of your trunk will effect the air space but even if you don't meet the exact air space needed it will sound good. Just make sure you have enough power for the subs. Also make sure your car has enough power too, i don't think a big battery and a 2 farad cap will do the job.

I am going to upgrade the big 3 to 0 gauge, and getting a 200A alternator //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I picked it out myself //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Which would be louder 1 15" L7 ported, or 2 15" L7's sealed?

 

[pcnbaseball44 10+ year member]

Wouldnt you need to get 2 ohm subs to wire down into a 1 ohm load or would you still use the 4 ohm subs since its double the wiring since their DVC subs? Just helpin ya or making sure, im kinda confused on that.

 

[swoosh 10+ year member]

Nope, you can do it with 4 ohm DVCs. Hook up all the voice coils in parallel, subs in parellel with each other. Ends up at 1 ohm

I'm thinking of just doing 1 15" ported, giving it 4 cubes to its self, according to bassbox pro it will be louder than 2 sealed.

H: 14"

W: 22"

D: 25"

Will have the sub firing up and the port coming out the front into the cabin when the seats are folded down. Like this will have the back of the sub almost right up against the slot port which has these dimentions which should tune it to 34Hz.

Port:

H: 4"

W: 12"

L: 20"

That look okay?

This is the Bassbox 6 graph of it's response. Look good for a couple of comps and loud daily listening?

Thank you,

Anthony

No one has any comments on the box?

If you want designs for your box check out the other sites like caraudiomag.com

If your using an L7 I would sugest using a lot of plexi-glass just to show people the beauty of the sub or have it mounted on a custom built fiberglass box.

I plan on doing some glassing //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

swap the hifonics for something that actually does what its rated at.

 

[swoosh 10+ year member]

I've heard they put out decent power? I think that guy that got his tested had something wrong with it, I don't think they would manufacture them having 10% distortion @ 1 ohm rated power. If it does, I'll return it.

bump

 

[swoosh 10+ year member]

Well, I'm not sure that I want to get a 15" L7 anymore. Anyone that has seen the back of a 2nd gen AWD dsm knows that there isn't much room. let me draw you all a picture.

Those are just about the max dimentions without dipping into the spare tire well. Seems to me to be close to 4 cubes usable space. With the 14" heigth there is still a little room for air to move. I am thinking about using that box right there and having the sub(s) on the top firing upwards to the top of my trunk and my hatch glass the farther forward they are.

Where it makes the jump from 14" to 20" is the start of my rear glass, all the way up to 24" leaving me little room to see out the back window. I would like to not have it go above the rear window, it will put me in a higher class for comps. Making it hard to see also.

Where the box gets narrow going from 35" to 22" could be wider but I would have to build over a small bump because that is where my shock towers are and the plastic on them slopes down into the trunk/hatch.

Also, there is a little room on the back of the box as the back of my car curves, leaving space to have a port be back there having enough air to "breathe".

Money wise, I don't want to spend thousands and thousands of dollars. Probably not more than $1000 (just for the subs and amp possibly). I want to hit at least 150db in this car. A friend of mine hit 144.9db in a chevy malibu with 2 12" kicker comp vrs in a small ported box. If it was possible for them to do that, I want to beat that by quite a bit with my car. I'm hoping it won't be too hard considering that My car is tecnically a hatchback.

Thank you all very much,

Anthony

I won't have the money for a little while yet. Although, if someone decides to help me out through this, to where I can get the most out of this type of setup. I will be willing to make a small donation for helping me as soon as I get some money. The reason I am figuring this all out now, is so I have a plan and know what I have to watch for good deals on I also want it to be removable if I need to remove it.

Edit: Help me!!! So I can shut up about this already lol ****it! lol
