So I m building a battery powered speaker enclosure. I have a 100w 2 chan amp (50watt rms per chan) and 2 6.5in speakers.?
I m trying to determine the
capacity of the battery I need to get to last me a good 5 hours. By my
calculations the amp will pull 8.33A which I m assuming is under full load.
But my that calculation, ive found that I would need roughly a 100Ah battery
to last me 5hours. Please let me know if this does or does not sound right.
Thanks
4 AnswersEngineering6 years agoWeak erections. Especially when sitting or lying down?
I'm 28yrs old. In shape, exercise regularly. I drink occasionally. I don't do drugs.
It started about the beginning of this year. It seems my erections are not as strong as they used to be. I remember my erections being so hard to the point it almost hurt. When I sat down or laid down they were still strong. My erections would point up.
Now it seems as if the blood isn't being trapped as well, making my erections weak, especially when sitting or laying.
When I masturbate, I have to hold it at the base and tilt it slightly towards my legs to keep the blood trapped.
I'm not sure if it's a psychological thing or if maybe there is something wrong.
Anyone with similar situations and have been able to overcome this?
3 AnswersMen's Health7 years agoPenis not as hard as it used to be?
I'm nearing 28yrs of age. I'm in pretty good shape 6'4 215lbs. I workout on almost a daily basis. If I dont go to the gym i usually run about a mile. I don't smoke. I drink maybe once or twice a week. I take multivitamins. I masturbate maybe 2 times or so a week.
I just noticed earlier this year that I can't get super hard like I used to. I used to get hard to the point it almost hurt.
Now when I have sex and the girl is on top, sometimes I find myself fighting to keep my erection at 80%. When I'm on top it isn't a big issue, but it's still not 100%.
I have noticed that I don't get aroused as easily. Could it be that subconsciously I'm not excited?
7 AnswersMen's Health8 years agoCondom slipped off after ejaculation.?
My condom slipped off after I ejaculated. I don't believe it went too deep and it was only in her vagina for 2 seconds. I want to say all of the sperm was still in the condom, however there may have been leakage. Between the spermicidal lubrication on the condom and her peeing immediately after pulling the condom out, how likely is it that she can become pregnant? Should I purchase Plan B?
3 AnswersPregnancy8 years agoJava recursion question?
So I'm trying to get a better understanding of how recursion work. I understand it's function calling on itself, however the only examples I can find are of factorials and fibonacci. Anyway, here is one problem that I'm stuck on. She tells us the answer is 4 but I don't understand why.
public int mystery(int n){
if (n == 1)
return 0;
else
return (1 + mystery(n/2));
}
What would be the output if n = 16. If it is infact 4, could you explain why. Thanks in advance.
2 AnswersProgramming & Design8 years agoWhat kind of lawyer do I need?
My previous employer has sent me numerous letters stating I owe them money for some strange reason. The letters were vague and stated "possible reasons" why this may have happened. All of which were tied to full time employees i.e. PTO. I was part time and had no access to PTO. I basically got paid for what hours I worked. I would think if there was any mix up, that should fall on payroll department not the employee. Anyway, it has been exactly one year since I worked there. Any help would be awesome.
3 AnswersLaw & Legal9 years ago2005 GLI RPM drop in 3rd gear?
I have a 2005 MKIV GLI 1.8t. Anyway, lately I have noticed (while using tiptronic) that while in 3rd gear the rpm drops at around 3300 for like a quick second. This only happens in 3rd gear at around 3300rpm.
The only mods I have on the car is an upgraded diverter valve. I've check the hoses attached to the DV and theyre all secure.
2 AnswersMaintenance & Repairs10 years agoChipping 1.8T tiptronic.?
So I bought an automatic 2004.5 GLI 1.8T w/ tiptronic from my buddy a few months back.
Anyway, I'm looking into getting a unitronic stage 1+ performance software. I plan on purchasing an aftermarket air intake and diverter valve as well.
The only issue I have is that my car is an automatic, so I'm not sure how this ECU flash will affect the tiptronic. I've read there is a GIAC tip chip which I found on awetuning.com, but I'm not sure what I need. On the page I linked below, there are 6 different options varying in price. I think I need the race gas performance software, but I could be wrong. That's why I'm asking.
So to sum up my question...;
Is the tip chip needed in addition to the ECU mod from unitronic?
If so which of these do I need.

1 AnswerOther - Computers1 decade agoStrange square symbol in my friend's process list...?
I was cleaning up my friend's computer when I came across a weird square symbol in the process list. The symbol is this ☐ I think the alt code is 2610. Anyway, I've scanned the computer with numerous antimalware programs including malwarebytes superantispyware and adaware. Nothing unusual is happening with the computer, but I'm afraid it could be a trojan. Anyway, if you have any idea what this is let me know thanks. BTW I have killed the process, so it doesnt start when windows boots.

2 AnswersChemistry1 decade agoOverclock problem on windows 7 64bit..?
I just installed windows 7 64bit on my computer. I originally had windows 7 32bit, but I decided I want to install more memory. Anyway, I managed to keep my OC stable on windows 7 32bit, but for some reason I keep getting the BSOD in 64bit version indicating instability in my OC. I know for a fact it's the OC that is giving me the BSOD, because when I run my CPU at stock settings I can run 64bit all day long.
Any idea why this is? Is it different OCing on a 64bit install of windows? BTW this is my first 64bit OS.
4 AnswersAdd-ons1 decade agoFSB:DRAM ratio question.?
Does a 1:1 or 1:2 ratio make a bigger difference in speed compared to 3:8 ratio?
Right now my FSB is at 200 and my DRAM is 533. I have 2 x1GB sticks of DDR2 1066 running dual channel obviously. Well theoretically, to get my ratio down to 1:2 with my DRAM at 533, I would need to set my FSB to around 260. But if I keep my FSB at 200, all I need to do is "downclock" my DRAM freq to 400.
So my question is, is it better to run my FSB at 200 and my DRAM at 533 with a ratio of 3:8 or FSB at 200 and my DRAM 400 with a ratio of 1:2?
Any input would be great. TIA

1 AnswerOther - Education1 decade agoEngine temperature gauge and A/C problem?
I have a 2001 Chevy Impala with around 60K miles. Anyway, just the other day the temperature gauge in the dash stopped working and the A/C stopped blowing cold all at the same time. I'm not too sure if these issues are related, but I can't seem to find what is wrong. I think it could be the water pump, but I don't know for sure. I've tried recharging my A/C, but that didn't work at all. I also checked the fuses thinking maybe a fuse had blown, but they are all good.
Any ideas?

1 AnswerHobbies & Crafts1 decade agoAnyone else have problems with piratebay?
I've never had a problem with TPB before, but lately I get this pop up window asking me something like "do you wish to continue on?". Before I get a chance to do anything it will start a fake scan.
After closing Firefox, I scan with superantispyware and malwarebytes to find malware.
Anyway, I have zone alarm, AVG, adaware, malwarebytes, and superantispyware and do regular scans so I know my computer is clean before I visit the site, but as soon as I start navigating within the site I get hit with the malware. I don't even download anything.
Any ideas?
