some types of caulk create vapors that in a sealed enclosure can weaken the foam surround. I forgot which kind it was. use google.

Well it is a commercial grade switching power supply, and the voltage is adjustable. normally i have it set at 13v, for normal use.

I'd love to make it, but 500 miles and i only get paid $700 a month, idn, i gotta save maybe u can move it a lil later, if not thats ok.

I was just curious, but my 1610d hifonics amp gets warm at idle, its hooked up to a 14 volts 58 amp power supply, and if its not doing anything it gets warm, but if i turn the music up about a 1/3rd the way it stays cool, is it a wasted energy thing or what??

well this guy just wants output, i like my sq, but he doesn't car, just as long as its loud, and doesnt sound like its a sub from the 80's

I got the box today/monday, yay I will get pics up in a day or two, the sub and neons are installed Its not in a car yet but it looks awesome and sounds pretty good for just sitting in my living room.

This is for a friend of mine, he doesn't care about SQ that much, he just wants an ok sound that is extremely loud, so i'm basically looking for a cheap 12" spl subwoofer. He would like to keep it under $150 per sub. He wants it really loud, i'm talking 140db loud if possible, th cheapest sub that you guys think can hit that, he wants two 12" subs.

i figure that to. we can just wait for a real pro to pitch in and see what he says.

ya, I got the carpet because I think it looks nicer with the light and all, but I have thought about it and wondered if it would improve sound at all?? as in how some people put padding in there box's to make the sound not reflect around the inside of the box. hopefully it does help, then that would be sweet.

ok, i can't wait to get it , plus i get my license back on the 19th, so i can have my new box with my somewhat new sub, and I can get to hear it at full power for the first time

Well if you read through this topic i think it says a xcon, not sure, but ya i'm putting a "15 ssa xcon in there with a neon.

Yay, hopefully my new sub enclosure is gonna arrive monday. I will update you guys with pics once its all together.

I agree, just sell it and go buy a second battery or a better alternator, caps just strain your alternator.

Also i'd like to add, that this thing is gonna be great for testing various things, because the voltage is variable between 1volt and 18volts at 58amps continuous. Its very accurate to, its really easy to adjust voltage by only 0.1v at a time.

I got this power supply off of surplus, I looked it up it had a msrp of $850 and I could find it new for cheapest at $350 in new condition from only one place since this thing is 10 years old, I got mine used, but it seems to be barely used, no scratches and barely a spec of dust on it. I have a multimeter hooked up and under a heavy load it only dips down 0.5v and the power supply isn't even warm. Ive been looking on ebay for a long long time waiting for a good deal on a power supply and i saw this one, I got it for $75 and so far its working great. it all looks like overkill duty parts it weighs a ton. here is a link to the power supply I bought. LH RESEARCH 18VDC @ 58 AMPS SWITCHING POWER SUPPLY - eBay (item 220539515037 end time Mar-25-10 15:56:49 PDT) Either way its only gonna power this sub for 3 weeks, and then from then on it will be used for a testing power supply only.

well I have the power supply running at about 15v and it works and sounds fine, I haven't been able to turn it up since its dark outside right now, but I will let you guys know how it sounds tomorrow.

i was thinking of that but they don't have a uniform light i want this to be perfect because once i put this in the box i plan to never take it out.

huh, I am but what would a neon have anything to do with sound quality, it won't affect the way anything sounds. if your referring to the rca jacks, I would hook it up to the output jacks on my subs amp. so it won't affect anything.

well i knew that the wattage will increase, that stuff is stated all over google, and car battery's go dead when u use them, this isn't a setup to test my stereo, this is my home theater sub woofer. I use it for hours on end, and currently I am using a 12v 16 amp power supply and ive used it for weeks now and it gets pretty damn loud for how under powered it is. so with this new power supply of a similar type it should get a lot louder than it currently does. so if you where talking about that i didnt know the wattage increases with a voltage increase i did know that, i was asking if there where any benefits besides the increased wattage...

someone will go to jail lol, idn.

well they have already tried shattering a car window with a sub, but the said it was busted, which we know a window can break from bass.

uhhh, if you think this then why don't you correct me and tell me what your talking about. because i am clueless at this point.

If your box is the one in your display pics its a pretty nice box, only real difference is mine has windows. Now me trying to get the turquoise neon in there so you can't see the neon itself from the outside is gonna be tricky.

ok thank you I will do so in a few hours.

at 18v, yes i understand?? what are you getting at? i may not be that experienced with car audio and I am still learning but I do know my electricity very well. The only thing that I can see that you might be getting at is the the amperage is so high that the wiring can't hand it, but doesn't cars alternator but out 85-300 amps depending on what alternator you have. Otherwise I don't know what you getting at. And then why do they make 14.2v 150amp switching power supply just specifically for car amps for the house.
