trust us man. that's all im going to say. you should trust us on this.

$20 he doesnt listen to us lol.

chat used to work perfectly for my when the forum changed but then after a month or something it went back to this problem. and when i launch in a new window, i cant go into private chat, open emoticons, or really click on anything. does this on any computer i have used. hmm... seems to be a problem with the carbon redgrey theme. blood looks like its working for chat.

3" ports always cause noise in the systems i've heard with them. go with a 4" if you can.

yep, costs more but its the least resistance possible.

run the ground all the way up to the front battery or to the engine. grounding to the engine is grounding it to your alternator.

in the old days, it was always 2x resistance = 1/2 power. today you have companies underrating their amps at 1ohm. BUT they tell you an accurate number at 2ohm. thats the best explanation I have in my arsenal to answer your question. and ive talked to guys that have been doing this a lot longer than i have that said the same thing. you can make an amp to do full power at 2ohm and it'll actually do less power at 1ohm. i believe thats from heat loss but im not sure.

first off, if you need bracing on a joint, then you suck at building boxes. plain and simple. go ahead and argue with me if you want to.second, read the thread.

the website is still there but it looks like they are finally updating it.

the amp isnt even on their website still, right? been well over a year and they didnt update it for some damn reason.

think you're going to notice the difference at all?

sorry, i forget who it is but there is a vendor for crescendo on this forum. but im curious why you care what the roll off is?

you going to put a wine refrigerator in there too?

that barrel is going inside your trunk? lol this will be interesting. take lots of pics for a build log.

hahahaha, your making a barrel into a speaker enclosure? thats pretty funny. i wonder how well the side of the barrel will hold its seal when its being vibrated. how do you put the bottom on once your done?

i dont think you understand where some items are strong and where they are weak. a metal band wont do anything over the long spans across the box. it will only put pressure on the edges. try making a 3 layer strip of fiberglass as long as the longest panel in your box. see how much it bends. i had the same idea when i was starting to get into audio. ive been there, i know. keep it simple and just put in a brace. a simple dowel will do as much if not more than all that fiberglass. it doesnt have to be as complex as you think.

heres is a little bit of dynamat. look how its clearly been pressed over the entire thing. his looks nothing like it.

look at the foil in the first pic. there is hardly any evidence of pressure being applied to the SS. looks like he slapped it on and scratched the middle of the tile. and later you can see where he did put pressure it stuck because the black part clearly looks different in the middle.

except this isnt a fiberglass box he is talking about. he's talking about adding fiberglass to a wood box for structural integrity. good job reading the question boss.

fiberglass is fairly flexible over one large flat area. thats why you always see it in tube or round shapes or with ridges to create more strength. it'll be a lot cheaper to just put another layer of wood on there or brace with a dowel or something. you're just going to throw money away on fiberglass.

you could wire one relay to make the fans run parallel then another replay to run two in series. so one switch position would be 12v and the other would be 6v to the fans. when i had fans i just ran them in series because they were loud and they were on every time the amps were on. or you might be able to put a resistor on one end of a switch and no resistor on the other end. find out how to do the math on the size of resistor you need to pull the voltage down to what you want. that would be the easiest way.

ya, that little guy was definitely unloading. i wouldnt push it that hard in that box until he gets a buddy. no reason to rip a spider or crinkle a former before its all together.

so that box is made for two subs and you had one playing in it on a 3000w amp at 1ohm? thats brave lol

you should go straight batt to batt.

so the subs that are not having this problem, will have the problem if you unhook the problem side? if thats the case its definitely an unloading issue inside the box, i would say.
