Assuming 3/4" mdf is used' date=' 0.615 cubic feet or 0.0174 cubic meters, or 0.0000000174 cubic kilometers[/quote']

if the INSIDE dimensions of a box are 24" x 12" x 6".then what is the INTERIOR airspace....

answer is 1ft^3....

to get .615ft^3..the INSIDE dimensions would be 22.5" x 10.5" x 4.5 "

sorry, inside=interior..hehe..he musta thrown in a trick question..hehe

Kids, there's a prime example of what extreme SPL does to you over the course of a few years.

all the stuff I think I know...

7. On a bosch type relay commonly used on an alarm system what are the coil numbers?

85, 86

8. On a relay commonly used on an alarm system what are two closed contact numbers?

87, 87a

10. To block low frequency sound from a speaker would you us a coil or capacitor?

cap

11. What is a common use for a diode in a car alarm system?

to rectify voltage? or make current flow one way and not the other

12. Should amplifiers fuse be at car battery or Amp or trunk or radio?

battery & amp?

13. To tune a CB antenna to a higher frequency should antenna be longer or shorter?

shorter

15. What is FM multi-path and how does it affect the sound?

interference caused from the reflections of large structures

17. What are the electronic symbols for Voltage, Amps, Resistance, and Watts .

E, I, R, P?

20. What does a crossover do in a speaker system?

filter out frequencies and direct them to corresponding drivers

23. Where does the remote wire on a car amp. go?

to the radio's remote lead

24. Explain brifly how police radar and laser speed detection equipment works.

a radio wave is sent out, and based on the time of reflections, an instantaneous speed can be deduced

28. How many octaves are in the normal human hearing range?

about 10? 20 * 2^10?

31. Two 4 ohm resistors wired in series will equal ohms.

8

32. Two 4 ohm resistors wired in parallel will equal ohms.

2

33. A 4 ohm and an 8 ohm resistor wired in series will equal ohms.

12

34. What purpose is a gain control knob on an amplifier?

control input sensitivity

36. Explain HF, VHF and UHF

high, very high, and ultra high frequency. tv channels use vhf for channels 2-13 and uhf up to about 60 or 70?

38. How many audio tracks are there on a normal cassette audio tape?

4. stereo signal for 2 sides

49. If you powered an audio amplifier into a 4ohm dummy load with a test signal and measured 10volts output into the dummy load, what would the power in watts be?

P = E^2 * R so 25 watts

50. If the inside dimensions of a box are 24in and 12in and 6in then what is the interior airspace of the box?

24 * 12 * 6 or 1ft^3

and don't forget ? #52

52. Do you really care about all the previous questions?

36. Explain HF, VHF and UHFhigh, very high, and ultra high frequency. tv channels use vhf for channels 2-13 and uhf up to about 60 or 70?

tv channels start on the low-band VHF channels...they're 6 MHz each in bandwidth, for the audio and video carriers. Channel 1 (or what used to be 1) is around 54 MHz, now the 6 meter amateur radio band. There's a station in Alaska (KEND, I believe) uses the Channel 6 audio carrier frequency to broadcast...technically illegal, but the FCC doesn't care as long as they broadcast a webcam of their studio on 6.

UHF television is much higher up in frequency, and if you have an older UHF television, you can receive cell phone towers, only a few MHz higher in frequency...

and what does this have to do with car audio or installing...absolutely nothing!! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

why are people wasting their time with this? most of it is straight out the MECP test. and we all know how much difference being MECP certified makes..........

it might not be a huge accomplishment in your eyes, but 10 to 1 says you couldn't pass it. the MECP test covers the basics of 12v knowledge and represents the absolute minnimum knowledge you should have before ripping into other people's cars and getting paid for it. just having an MECP cert doesn't mean you're a good installer. it simply means that you have learned enough to be able to lean more //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

BTW

There's not just one MECP test. The standard "silver" test is available to anyone. The higher level tests require proof of experience (ie working as an installer) and is MUCH more difficult and encompassing. The good folks who dreamed up the MECP certification program realize that it takes real world experience, not just book-smarts to be a top-notch installer.

PS: If you can't answer at least 30 of those 50 questions, you need to check out the ol BCAE website and start reading up. You really can't consider yourself a hobbyist if you don't know the basics of 12v electrical systems //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i think the www.12volt.com test is way harder than this one.

 

[sumone 10+ year member]

I don't plan on being mecp-certed anytime soon, but it's nice to test yourself. and don is right.

I remember some years back (I was 13 or 14) I found this list mapping out radio frequencies and who leased what and which were reserved for stuff and such.I remember I thought I was so cool walking around with a 100 page report of numbers...lol

 

[sumone 10+ year member]

isn't it the same...
