    Speaker help please

    Ok I installed the above tweeters and it made a hell of a difference.  I'll have to figure out how to get a 10" sub installed in my truck without taking too much space now. Thanks AudioGuru for your input.

    Hi audioguru Yes its here's the link for the specs. It does say 4 x 50 W S-MOSFET power output but its probably peak watts. http://www.sonystyle.ca/commerce/servlet/ProductDetailDisplay?storeId=10001&langId=-1&catalogId=10001&productId=1003305&navigationPath=n32150n32153 At...

    I have a sony CDX-GT310 in my toyota pickup. It puts out 4x55w in 4 ohms.  I have just have cheap 2-way speakers installed in the front and back. I got 6"round 120W in the back and 4" round 2-way 90W in the front under the dash almost. I know its a cheap system but it sounds ok except I find...

    Can someone suggest a good 50 to 75Ohm impedance matching transformer?

    Ok I was told the the impedance of the stereo antenna in my truck was 75 Ohms, so I thought maybe I should match the impedances because initially I thought the signal loss would be roughly 2/3 of full power but I read up on the net while awaiting your response and I guess the signal loss from...

    Can someone suggest a good 50 to 75Ohm impedance matching transformer?

    I use a FM transmitter in my truck and would like to use a normal FM antenna to transmit the signal. I think I will need a RF impedance matching transformer that will match the 50ohm impedance of my transmitter to the 75ohm impedance of the FM antenna. Can someone please suggest a good one that...

    fm transmitter scematic required

    I researched the Ramsey model but they are about $60 more for a kit and about $100+ assembled. Second is the fact that EDM is also microprocessor controlled and has digital LED readout. If I can quote from their site I found all the feedback I read on all the independant website was all...

    fm transmitter scematic required

    using the stock whip antenna I did some preliminary range tests. The Tx was installed in the cab of my truck with the antenna running up and down the mirror which isn't the best placement for it but nevertheless I was very happy with the range I received.  using a fairly good quality FM headset...

    fm transmitter scematic required

    I recieved my EDM transmitter last Wednesday.  It is an awesome little unit. I am so impressed with the sound quality. It really sounds awesome especially when I connect my cd player to it. Sirius Sat Radio sounds alot better too. Seems to have a really great pre-emphasis stage in the input. The...

    Cold Heat Soldering Tool

    I have oneand you wouldnt want to use it on sensitive electronic equipment as it circulates a relatively high current through at the point where you are soldering. While it is good for welding small wires together and such I wouldnt recommend it on electronic circuitry.

    Got a couple questions regarding this fm transmitter

    hehe geez your fast I re-posted my last post after re-reading your post. I thought because you said that Canada/US had to much pre-emphasis that maybe I should go with the 50uS. Now I understand that I have to go with 75uS so that the sound won't be muffled in my canadian reciever. Sorry I am...

    Got a couple questions regarding this fm transmitter

    Ok so if I understand correctly I have no choice but to go with a pre-emphasis of 75uS otherwise if they set it to 50uS I will be getting muffled treble and thats certainly not what I want. correct?

    what FM pre-emphasis setting should I ask for? I have the choice of 50uS or 75uS.

    fm transmitter scematic required

    ok you are probably right , I was only going by what I read on the diy site.  They said it would put out 20mW but I read somewhere else someone posted that there must have been a typo and at most it would be 10mW.    In any case I think I will be happy with the EDM-TX-110EP I ordered Have you...

    fm transmitter scematic required

    yeah but I was thinking that because the 1W amp needed 100mW to drive 1W out that with the 10mW or so that the micromitter has (without the attenuator) that I might be able to drive 100-200mW. Anyway i decided to return the micromitter kit and bought the EDM kit the is switchable between 10mW...
