car amplifier into PC

post #1 of 13
Thread Starter 
I have an amp and sub that was given too me, and the previous user could not get it to work (my girlfriend, her exs bro had installed the amp into her car) and i looked and noticed it didnt have the rem wire plugged in, but girls being girls said i wasnt allowed to touch it lol. anywho few months later its been given to me and i dont have a car yet, but i tried to plug it into my computer to see if i could get it to work. I want to know if i went the right way about plugging it in or if i did something wrong, as it still does not run.

I got the molex connector, snipped a black wire and a yellow wire, screwed the yellow wire into the positive terminal of the amplifier and the black one into the negative terminal. i got a spare piece of wire and screwed that from the positive terminal in the same plug as the yellow wire into the REM terminal. so as far as i am aware as the power supply is turned on, there will be a 12v power supply into the amplifier and into the REM so it should turn on.

Problem is there is the protection light turns on. the amp does not turn on. am i doing it wrong, or would the amplifier be buggered? i am using a 750w seasonic m12d which i THINK has 2 12v rails, both of them can handle 36 amps. im using a fusion fe402 amp which should require roughly 33 amps to run.

what am i doing wrong? or any info on how to diagnose the problem would be rep +

That should work, you are correct in putting the Yellow(+12v) on the Power Terminal, and the Black on the Ground terminal. Then you should run(which you did) a wire from the power terminal to the Remote terminal. I keep a PSU on my bench in the garage for testing audio equipment and lights like that. you should go ahead and take an mp3 player or something like that and hook it up to the two RCA's. sometimes the amp will cut off when it is not receiving a signal.

what kind of amp is it? And the amp will only draw what it needs to run, it might be capable of drawing 60 amps, but it won't ever draw that unless you turn it up loud.

Do you have to be aware of impedance level of the amp or is it just applicable for speakers and subs?

ok thanks for confirming i have it set up correctly. Im using a fusion fe402 amp with a fusion encounter sub or something, the sub and box is huge but when i power up, nothing happens with the amp except the red protection light comes on. as far as im aware this could mean anything from the amp already being fried (its 2nd hand and ive never actually seen it run before) or the ground isnt working or anything.

Im beginning to think the amp is buggered, but i will wait to try it in what its designed for first - a car lol, before i jump to any conclusions.

does anyone have any methods of diagonising the protection lights cause, or to find out if the amp is buggered?

Open it up, its a few screws and you can see all the circuits of the amp. If something is blown, it will be quite noticeable. Also, do you have the speakers hooked up to it when you are powering it on? And I found this on their site, I know its not much, but here ya go:
Quote:
Protection LED On
- If the red protection LED is on it may be that the amp has gone into Thermal protection (overheating).
- Let the amp cool down for 15-30 minutes and try again.
- If the amp still goes into protection it could be the result of a speaker/sub problem, disconnect the speaker/sub from the amp and turn the amp on.
If the power indicator comes on and stays on that would indicate that you have a problem with your speaker/sub.
- If the protection LED comes on you may have an intenal problem with your amp.
- There could be a fault that needs professional diagnosing and servicing.
- If the problem persists please consult the authorized dealer at your place of purchase.

can you please take out its fuses and give me their ratings. That will tell you the power of the amp. Its normally 2 per channel.

or just all the fuses on the amp, I have a mono amp that uses three fuses. They have colors and stick out of the side.
