I'd also say save your money if you're happy enough. No reason to change arbitrarily.

infrasonic is the same thing as subsonic. So you'll want to set it to 25 hz or so.

Kinda strange that they don't double output when linked. Where does the other 500 watts go? But if they give about 1k per sub, that'll work. Also, I merged your threads.

dump that hoe and get with the blond. for sure. End.

I wasn't very hungry after I got home from my 3 hours of basketball playing so all I ate for supper was a salad, an apple, and yogurt. I think this may have been the first time in my life that I didn't have any meat for supper.

haha that parking job was funny peng. I coulda parked my Explorer in there without any problems.

You seem like a nice guy that keeps getting stepped on. You gotta stand up and say screw it. Change the locks on your house if you have to, seriously call the police if she tries getting in or whatever. If she has stuff at your house, tell her to move it or else you're putting it on the lawn. Then do it. Drop that girl, man. That's not love.

I agree, this girl sounds like poison. I know it sucks to seem to have wasted all that time, but you can't let that decide for you. If you think about it, what are your options? You only have two, and that is accept the loss of 5-6 years, or else have a loss of 80 years, aka the rest of your life if you keep trying to put up with this. It seems as if you have made a valiant effort to help her, and you really, really don't want her dragging you down with her financial problems, especially in this economy. Unfortunately it seems as though she's one of those people who really has to fail in order to learn the lesson, and you really don't want to be there when it happens because it'll most likely ruin your credit as well when you try to help her out.

Sounds like clipping. How are your settings on your amp and H/U set? And where is your volume on you H/U when bumping? Friend of mine is putting 2,900rms to each of his DD 9515"s. And he doesn't get a smell till the end of the second or third song depending on the notes. And it is 2,900 after imp. raise and voltage drop. It doesn't have to be clipping since he's giving the sub twice what it's rated for. Also, if you get a smell every time you play, that's damaging the sub. If you think about it, what is that smell from? It's from the glue getting hot and evaporating a little. If you keep taking a little at a time, eventually there won't be any glue left.

I take it that 1.88 cubes is before port displacement? Is sub displacement factored into that already?

he said the pioneer sub didn't do it, though. I'd agree with bkolfo, sounds like something got into the pole vent and is now rattling around inside. and as he also said, scratching sounds when pushing down on the cone doesn't always mean anything since it can scrape with just a touch of off-center pushing on some subs. Plus since you say it doesn't scrape sometimes, I'd imagine those are the times when you push it straight.

I meant the speaker outputs, did you test those with a DMM? If so, did it read anything or just a 0? Also, not sure what head unit you have or if you had an amp hooked up before this, but some head units have a subwoofer output on/off switch. That would obviously need to be on. Or if it's like my home theater receiver, settings (crossovers, etc.) for other speakers turns on/off the sub output by itself. That's annoying, ha.

wow I said though like 14 times in that post. haha

That's a pretty decent calculator. I think it is a bit conservative, though. I entered a sub I've used and it recommended 78 sq. inches but I had 50 on my box and it was ok. You can also download winISD, which will graph port velocity vs. frequency, and I think you just want to keep the velocity under .15 mach or so over the frequencies you'll be using, which is normally 25 hz and up or so. You need less port when using aero ports, though I've never seen or heard any exact exchanges. I think you can get away with about 2/3 of the port area of non-flared round ports, though. The flared end does add to the length a bit I believe. I got a sheet with the aero ports I ordered from partsexpress that explained this and the equations to figure tuning, but I don't have it anymore. You may be able to find one with a google search, though.

Not to insult your intelligence, but make sure you're putting the RCAs into the right hookups, some amps have RCA outputs as well. Have you measured the output voltage from the terminals with a DMM?

weather.com says tonight we may get large hail and tornadoes. I've never heard them actually predict tornadoes. But yikes.

I must have missed the beginning, what are you building there Tom? A Mars rover?

What makes them a bitch? Do they have the bolts instead of lug nuts? The holes seem small, but that's what thin-wall sockets are for . I thought directional tread + different sizes + big rims would make them a bitch but as Sean pointed out no rotation is necessary, so I'm not even going to worry about it... ah I guess I didn't look close enough to notice they were different sizes and directional tread when I looked through your thread. But if they're directional and different sizes in the front and back, you can't rotate them anyways (regardless of life span)! I think it's hilarious when I see a parked car with backwards-facing directional tread.

I think the main problem is just that your score was from such a low note. 36 hz is really low for an SPL competition, most guys are in the 50's or 60's. It's more difficult for subs to create higher pressures with lower notes. I can't see your signature because I have them turned off, but I think you should try a higher tune and/or a different box size to try and get your peak frequency up. 145 at 36 hz is really good though, don't kid yourself about that. I'd bet that if you tuned to 45 hz you'd see a 150.

ah damn the weekend is over.

What size tank do you have? small one, like 6 gallons. The otocinclus only grows to maybe 1.5", and other than that I just have two red tetras that I've had in there for like 8 months. They're also only about 1.5". I just have a small algae problem (have to scrape the glass about every month) because the only place in my townhouse for my tank is in my room and it gets quite a bit of light. Plus I don't have any live plants in there, though a few of those like mini lili pads were in the bag with the oto, so if they multiply then that'll help cut down the nitrogen. But I got the oto because I was bored with the same two fish and thought maybe he'd help my algae. I have some small snails in there, too, but they don't really do anything to it. That is how I started out and worked up to a 300gal reef tank. Couple of years ago I down sized to a 150gal. This was a bad habbit for me for many years. I still have a brand new 400gal sitting empty. wow that's huge. Would be pretty awesome to have a saltwater tank though, especially with living reefs. Just a lot of maintenance I imagine. And I've come to realize that fish are ok pets, great because you don't have to take them outside or watch them all day, but they aren't very interactive, obviously, haha. So it's not too much more than just owning a plant as far as companionship.

That kind of a tear gets there from being played and moving. So whether it started with the "rubbed" part or whatever when you first opened the box, or if it happened after you installed it, that's the cause. So I suggest not being defensive when asked questions about how it started and if the scratch it had when you got it caused it. It appears that the "big scratch" is at the end of the crease, right? If so, that's where it started from and it just promulgated out from there, around the sub.

I'd actually go with a dual 2 so that you can wire in parallel for a 1 ohm load. There are a lot more options for a Class D 1000 watt at 1 ohm amp than at 2 ohms. Plus if you chose a class A/B amp, most of those are 2 channel amps that are stable at 4 ohms bridged, which is what you'd get wiring a dual 2 sub in series. So you would win with either amp class you wanted, generally. Edit: Ah, you beat me.

I guess I've never heard of a blowthrough in a car.
