Vid of my Atomic APX 18

So I just picked up an 8cf box the other day. Unlike my previous box, this is double baffled on the sub-face, and internally braced. My other box was also >4cf, so it is a pretty big difference. Since it holds together better, it hits cleaner (despite being larger), and really enjoys the low notes now. My current box is tuned @ 28hz. It is hooked up to a Rockford Fosgate T1001bd @ 1 ohm, for a potential of 1600wrms. I doubt I'm getting anywhere near that much power, since I don't have Big 3, I'm running 4ga power and ground, I have a stock 90a alternator, and I only have one battery (700cca Autolite 84 or something like that). By one battery, I mean it's the battery that is starting my engine as well, not one extra battery. Luckily, the Rockford is pretty efficient, so I can run it at full power without my lights fully dimming, but I still know its not getting enough power going to it (and from it, obviously). Also, everything is hooked up pretty ghetto and probably will stay that way, solely because I'm about to sell my car so I don't want to spend hours cleaning it up for nothing. And some of the "slapping" noise is coming from the wire leads in the sub, which are not woven. A new speaker amp is on its way, as the RCAs are being annoying and usually produce the alternator whine that you are hearing in the video.

To the point of the thread, which I'm hoping is placed in the right section. I took a few videos of it, finally. My car is VERY solid, so it doesn't flex as much as you'd think it would. You put the same amount of power in my buddy's Mazda 626, and it just falls apart. All I get is a little roof flex and trunk hop. I was a little jumpy in taking the video, because I was trying to catch all the flex I could, so I'm sorry if you get motion sickness //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

First video, a bass tester that sweeps down to what I would guess is 10 or 15hz



Can't wait for my next car (SUV, actually)! It's gunna be done well...1/0 big 3 and Power and Ground, Batcap (or something similar), bigger stock alternator, and probably a MB Quart Discus 2000. Heh heh //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

That thing makes a lot of noise.

The alternator whine? The rattling? Or the sub?

sounds like alt whine

Sure is. RCA input is loose on the speaker amp. I'm swapping it when it quits raining.

sounds like you need more power ...

Quite right you are...I need more power going to my amp, and more going to my sub. It's still insane...likely because it's so efficient

oooooooh ok. The camera exaggerated the rattling a ton. The rattling from the sub itself is almost unnoticeable. The rattling from the interior panels of the car is noticeable, though. I need a little more PhatMat lol

No love for my work, buddy? Let people know that you are proud to run my enclosures! Give me enough business, and I will design and build your next one for free, if you provide the parts. How is that for an incentive!

atomic sub with an RE dustcap maybe?

 

[s_carter 10+ year member]

yes it is a reconed apx18, and I heard this thing in person, it is a very good, sub, although it could definitely use an atomic recone to get some better sq out of it. my guess from hearing it in person, it sounds like tinsel slap to me. I doubt that it would handle a 30kw burp with the current VC that has been retrofitted, but it is still a beast!

Course I love your work! 'bout time you got an account here. Anyone local to Portland should give S_carter a try for boxes, they are cheap and well built.
