   Making your own amps
  Hey, I am getting a car soon and was wonderring if anyone else here had made thier own amplifiers for either thier car/home sterio/sound system.  It seems that all of the places around here overprice thier stuff and only carry subwoofer amps.  They have plenty of sub amps, but none for the entire frequency range(I kinda like to hear all of my music when I crank the volume... not just the bass)  I was kind of hoping that thier might be something like a standard diy amplifier that does what I want so I don''t have to do a ton of research... I don''t want to get caught up in yet another diy niche...  I found the site: diyaudio which has some very knowledgeable people, but seem to be way for into it than I would like to get.  Just hoping there is a simple standard... also would be nice so I don''t have to make my own circuit board, which wouldn''t be necessary on a standard circuit.ThanxDwiel   For all in need of free hosting for pics/etc:upload to ftp location: dwiel.no-ip.com user/pass = FreeHostedPics/gamedevYour files will be available on the inet immediately at http://dwiel.no-ip.com/~FreeHostedPics/Feel Free to create a folder there for your self!
  Even if you found an amplifier that covered the range of frequencies you want, your speakers wouldn''t be able to handle them. You''ll need a crossover and at least three pairs of speakers - tweeters, woofers and sub-woofers, one each for L and R channels - to get the whole audiophile experience. For really high frequencies (unlikely you''ll need those), you''ll also want a pair of squawkers.Dynamic response is characteristically uneven, which is why speakers are specialized to relatively small frequency ranges. The same holds for amps. ;  I was thinking about doing the same thing when the cassette deck on my car died, and I just wanted to set up a line in, but it''s easier just to get a really cheap amp -- I got a pretty decent one for $10 off ebay.  You could build one yourself, but it''s probably going to cost a lot in parts anyway. I''d just recommend buying one.   ----------------------------------------"Before criticizing someone, walk a mile in their shoes.Then, when you do criticize them, you will be a mile away and have their shoes." -- Deep Thoughts"If you have any trouble sounding condescending, find a Unix user to show you how it''s done." - Scott AdamsFaceHat Software -- Wear the hat. ;  Besides, if you want to do something really geeky, put a computer in your dash. MP3s, FM tuner, DivX, games, word processor... ;  Tazzel3D - you should save your signiture jpg without compression and then you won''t get those artifacts around your letters. ;  Also, the currents going through some parts of the amp can be quite dangerous if you don''t know what you''re doing(ie not an electrical engineer) ;  Just get a few transistors and a variable resistor and you''re laughing. ;  Yeah, I guess the ''just buy one'' (off ebay) is what I''ll do.  I was already planning on putting an old computer in there   But the sound output isn''t amplified enough.Tahnx for the suggestions.  BTW, what kinds of things should I look for in an amp?  most people don''t give frequency response curves do they?Thanx for the helpDwiel   For all in need of free hosting for pics/etc:upload to ftp location: dwiel.no-ip.com user/pass = FreeHostedPics/gamedevYour files will be available on the inet immediately at http://dwiel.no-ip.com/~FreeHostedPics/Feel Free to create a folder there for your self!
