Amp not working

[TFFantasy44]

I just received a 12' O Series (dual 4) from eD, hooked it up to my amp, and it won't play. I checked & rechecked all wiring from the amp to the sub, and everything, but it still does not play...only, when I turn the car on, it plays for a split second, then the status light immidiatly goes red, and it will not play at all afterwords, so I know that the sub is okay. Even without anything hooked up, the amp still has a red status light (is supposed to be blue). I figure the ground is bad, but I did have a sub with the same amp and wiring before this, and it played fine. Any ideas?

btw, I have an Audiobahn HQ4125 amp (2x500W RMS @ 2Ohms/1000x2 @ 1Ohm) and am giving the sub 500 watts.

try turning the gain down, like all the way down, then turn it up slowly
and recheck your wiring, fuses, that happen to my friend, but i found out that he had a really cheap amp (DHD amp) and he got a new amp, everything worked good

[TFFantasy44]

Yes I tried that, too - turned all the gains completely down, sub controls on the head unit down, all bass on equalizer down, and still no go. I checked each fuse on the amp, all where good, and the in-line one is good as well, obviously as the amp turns on. But, the same thing happens reguardless of whether or not I have a sub or anything hooked up - the amp is okay for less than a second, and then immediatly goes into a protection mode.

Mine does that when the power and remote solder on the circuit board touches...because Ive had to fix it once and if they cross over thats all I get. Who knows, weird shit can happen to amps.

[VTcommo]

Is the amp still getting power, caus i thought i had the same problem once, the light still came on saying that it was getting power but the fuse ends solderrd themselves to the side so no power got through. So try changing fuses, probably not it but worth a try??

[TFFantasy44]

Yeah, I'll try replacing the fuses - got some extras lieing around. I doubt it is it, since the sub hits as soon as the car is on and stops, but hey, I waited a month and a half for this sub. It WILL work.


Hmm...I still have my old amp, maybe I should hook that one up and see if it works?

It sounds like you need to go get smaller fuses on your power wire. If your fuse is to big on the power wire then it sends to much power to the amp. The amp is programmed to turn off if it receives to much power. Could be your subs are trying to pull to much from the amp??

never heard that one before, don't know how much I would believe it. If the amp isn't powering on, unhook the subs and try again. also, do yourself a favor and buy a voltmeter.

hahahahahahahahahaha

thanks, I needed a good laugh

[TFFantasy44]

No, the fuses are fine - I've had a sub hooked up to this before (plus a smaller fuse would just blow) power draw from the amp is fine, 1 sub that needs about 500W is receiving 500.

[sr20de4evr]

Does that amp really put out 2x500W RMS @ 2Ohms and 2x1000 @ 1Ohm, or is it 1x500 and 1x1000?

[Haibane]

it is 1x500 and 1x1000, they screwed up the specs, I have talked to audiobahn about it before. It is a mono amp anyhow.

[TFFantasy44]

? The amp I have is here:
http://www.onlinecarstereo.com/CarAu...roductID=13511
If it is mono, then what channels would I use to get the 500x1/1000x1?
****er didn't come with a manual. Anyways, before I tear my car apart in fury, anyone else got any ideas on what the problem may be?

[sr20de4evr]

Hm

how do you have it wired to the sub and how is the sub wired?

[TFFantasy44]

I've tried it all - parallel, series, and wiring each voice coil to a seperate, unbridged channel
