DC Level XL 15" Running on Kicker ZX2500.1 Box Help

[CleanSierra]

Run your current equipment for 4-6 months then. Don't waste money on a box now and use a design that crams your car as tight as it would. The reason I'm stuck on 12s for your car is cabin space. 15s don't hit any lower, so if that what you think, let's just correct that now. In a proper box built and tuned properly, 12s, 10s a d 8s can hit just as low. Will the 12s move as much air, not if both the 15s would be in an ideal setup, and 12s in an ideal setup. Here's the thing, you HAVE the right environment for 2 badass 12s to do EXACTLY what you want. Your cabin doesn't require 15s to pressurize it properly.

So, if you want to change up things, run ONE of your 15s in a badass simple ported box. I don't care for your design because of the port design, placement, or bends. A single 15 ported will show you frequencies you've been missing over your sealed setup, I truly believe that.

And as far as the offense, none taken. You're a good dude, I love your car and your install is VERY nice. I like how you've been really true to one brand regardless of anyone else's opinions. My suggestion, since you definitely wanna change up the current configuration, 1 15"(the CVX obviously) tune it low, feed it port and power and let er rip.

Thanks man well hmmm, I agree with that box I designed, it crams it tight, and I don't even know if it would fit with the port, so perhaps I should design the box for the 12's and build it, get it ready and then try to sell these cvx's cause seems like a waste to build a box then to tear it out again next spring, and 1 cvx is a waste for that huge amp imo, I agree I want the 12's, I know they would be nuts, well I guess thats what ill do, im gonna work on that box design, it would give me more of a trunk, what you think for direction to face them? subs up, port back? or subs up, port up? subs up port up would the best for building since one side has a slanted back, I am gonna get these subs listed on craigslist too I guess :Pyou think 3.5 cubes total, 31hz tune would be good?

Alright, so I designed a box for the 2 12's, it will work out way better, and I can mount the amp to the amp rack above the battery, and still have somewhat of trunk left, this is port up sub up, let me know what you think, cj18 recommened 3.5 cubes for these 2 subs, with around a 32hz tunning

doing 2 baffles, the subs will be counter sunk into the baffle so they are flat across

let me know what you think, I sketched a pic of what it would look like too

sick Mazda bro hopefully my Mazda will be up there one day

question for you guys, I was thinking of maybe just doing a single 15" sub now for a few reasons, I can run 1 of my cvx's till I can afford it, I can design a good box for it, price, since I will only have to buy one sub, and I was looking into box rise and impedence load, and was thinking of getting Dual .7 ohm coils to wire it to 1.4 ohms, my zx2500.1 is 2 ohm stable, but I have read many running it at 1 ohm, and this would be a comprimise, plus with box rise the amp will rarely if ever see 2 ohms or lower, even with the 1.4 ohm coils

So, if I did this I could do a level XL or Level 5, which offer the D.7 coils, what do you think this would be like compared to 2 level 4 with a final load of 2ohms, the 1 15" would get more power, I know its less cone area, but its just a thought, im just kinda disappointed of not having any subs for the next 3 months plus like I said this would save some money when I do go and get the 1 sub

[dereileak]

what do you guys think of 1 DC level XL 15" instead of 2 DC level 4 12"? I would just get the final ohm load to 2 ohms on either, mainly for price and it should still be more then enough I think, my amp will push 2845 @14.4v, what kind of power is the xl safe up to daily? it says 2200 rms, so its pretty close

A XL 15 will take 3k easy man Blake Hunt ran 12 XL 15's on 4 9k's at 16 volts a piece iirc. Clamped around 40kw. So a tad above 3k per sub.

what do you think of doing a ported box with my cvx for now, then putting a DC Level XL on that ZX2500.1 rated @2845rms, you think that is to much power for that sub? from what I have read is it can take the power, but gains are very low when you start going up above like 2500rms or so, its cheaper to buy on XL 15 then 2 Level 4 12's, a little less cone area but still with that much power

Ok So I think i am pretty set on doing 1 15", which should be plenty for this vehicle. I will run my CVX until I can afford the Level XL 15", so now it comes to the box, let me know how this box is, from what I have read between 3.5-4cubes is good, 50+ inches of port space is recommend I am running it on a kicker ZX 2500.1, which does [email protected], so the sub will be getting more power then its designed for, and from what I have read if you are overpowering you want to stay on the smaller size of the box designs (less power = bigger box, more power = smaller box)

Let me know what you guys thinks, I have enough room to design a perfect box for this 15", I am flat mounting the amp above the battery so I need to keep the box no more then 14 inches long at the top, 21 at the bottom about, I think I picked a good tuning and box size, port is pretty big, I designed the port like I did because it most effectively uses the box space, and since there is a slanted back I need to keep the port away from that
