That amp will work. You just have to be smart with it (which I hope you learned how to be after blowing the first sub). The truth is that a more powerful amp should just make it easier to blow a sub, since, well, it has more power. Just stay away from overdriving that amp to try and make up for the slightly less power and there shouldn't be a problem. If you're worried about output with that amp you could build the box a little larger to get a little more efficiency or go with a higher tuning frequency to get a little larger bump in response.

I live 30 miles from #9 Overland Park. I suppose it's ok, but it breeds yuppies and spoiled rich kids. Ick. My hometown/area was on one of those lists, like #2 best rural place to live in the US, haha.

Why the side-firing port?

Both up will be fine. There isn't a huge enough difference that you'd notice much, and since you have only 1" of clearance on the back side port up would be a much better solution.

is this for ported? What's the tuning frequency?

Is it really? haha. I've always thought I have an overactive mind. I get sleepy a lot and easily if I'm not doing anything actively. It's like my brain is either in hyperdrive or no drive, haha.

Oh, and the crossover is a Behringer CX2310. Nothing too fancy.

haha. it's not much. I had a Dayton Refernce 8" mid get damaged by a roommate one night when he was throwing a party and decided to crank my stereo. It's not totally ruined, there's just a few midbass notes that it kinda makes a tinny scratching sound on. Very few, and I really only heard it while playing tiger woods golf, haha. but enough to make me want to replace it. So it got relegated to sub duty on my fairly weak computer 2.1 system (Optimus receiver two optimus speakers which I think each have a 4" and tweet in them). While at college I didn't have access to wood box building equipment, and just felt like trying something different besides. So I chose legos. Went and got a box of them. It didn't really build as big of a box as I'd like (1.5 baffled it all the way around, haha. aka 3 little pegs/holes.), but it works. Well, a little. haha. It doesn't get super loud but definitely better than free air or anything. I have since inverted it to save some space inside there, haha. And here's what it looks like now: As is imagined, the box is the limiting factor. haha. It doesn't have a bottom as I decided that further saving bricks and using the carpeted floor as the bottom "sealant" would be all right. It doesn't sound bad at the low-moderate volume levels I normally play it at up here in my room and adds a nice lowend to the Optimus', which have basically nothing below 300 hz. But if I try to push it you get to hearing the banging resonance from the box as well as the air leaking. just starts sounding all farty. It has scotch tape all the way around on all the sides to help stop leaks through the cracks in the bricks. And has athletic tape sealing it to the top . It was just a fun little project to try. Wasn't ever expecting great results, but it's not worthless either.

I have some vanilla ice cream stuff, don't remember the brand (used it last summer). But it was so awful with water that I thought I was going to throw it back up a couple times. Then I decided to try milk and holy crap it was 100,000,000 times better. Actually tasted like vanilla ice cream that way. It became so easy to drink, I almost would drink it just for the heck of it whenever I felt like it.

dang those engine graphics are crazy. Rearranged my room today. No small feat apparently, even with the gf helping. It's been over 5 hours and I still have a few things to put away and hook up. Made sure to get the 2.1 stereo w. the lego box sub hooked up first though, ha. that way I can have some tunage for the rest of the time. But then I just kinda wandered onto this site as I was listening and setting up the Behringer crossover, ha. Now I'm stuck and not getting any work done.

with a big box and that much power, that sub should be blowing itself on that song because the last notes go down to 20 hz or lower I think. I'd check the amp. Is there a subsonic on the amp? Is it turned up too high? Is the regular low pass crossover set correctly?

That thing probably doesn't have more than an 90 amp alternator. I'd change that before the battery. That will have a bigger influence on your overall system voltage during bass hits than a battery.

man, looks like it's just going to rain all day. Oh well, wasn't going to do anything except be a couch potato anwyays. Does anybody know how much that mortgage insurance is for if you don't put 20% down on a home? I figure it depends on amount borrowed, let's just say 100,000 for roundness example.

I like bottom-mounting. Seems to give less in-room troubles as far as hot spots. As for a sealed box, 5.5 cubes will give you a QTC of .717, -3db point of about 31 hz.

just fyi, the mag uses xbl^2 too. Atlas is a respectable woofer though.

You'll always get a spark at the fuse. That happens whenever you put a positive charge to something metal. However, it's always better to have that spark be at the fuse than at the amp.

right

I'd do Stereo Integrity.

I think it's ok to quote the price since he listed it in a thread on the SI forum. Didn't he say (or at least estimate) that it would be 250 shipped?

You REALLY wouldn't like the ass end then. I was going to say, I think the front looks good but I bet the back looks awful. Just kinda get a hint of it in that picture. I hate those scrunched looking asses.

I'd try out the new mag. But that may just be me.

Man I got demolished by KU's middle linebacker today while playing basketball. Dude is like 6'2", 250 lbs of pure muscle. I'm not small, 6'3", but only 180 lbs. I wish I was shorter today, though, so that the two elbows he spun into me with would have landed in my chest instead of my stomach. Got the wind knocked out of me twice and I couldn't even run for about 5 minutes. It's still tender to even the slightest touch. Dude is a monster though. I'll be watching him next year for sure.

you just admitted abusing them and you want them covered under warranty?

humans are the best adaptive organism in the world, besides maybe bacteria. We can live in any climate and are smart enough to find or make life's basic essentials pretty much anywhere. Almost everything that can happen to earth has already been done, and some kind of animal survived. I'm not too worried about the continuance of the human species. Probably the only things that could do us in is an asteroid that completely demolishes the earth or the sun engulfs us. Somebody would survive a nuclear winter.

I believe that's what I've heard. I used a red top as my starting (and only) battery in my last car, and as soon as the battery in my Explorer goes, I'm replacing it with a red top as well. It's been a couple years since I've last discussed this, but the consensus was that red top is good for primary battery and yellow is better as a secondary. That's not to say the yellow top couldn't be your primary. It may also depend on if you play your stereo a lot with the car off. In that case it might get a little blurry as to which one you'd want. However I will say that when I was taking my stereo out of my last car with the red top, my vehicle lights were on for probably 8 hours because I didn't disconnect the battery. and when I went to start it, it was as if it didn't even know it had been discharging. started right up without so much as a half-hiccup.
