Oh yeah forgot to mention, amp doesn't get hot
Got a serious problem thats a bit strange. I am currently installing the audio half of my carpc system and recently installed my jbl gto6000 amp. I used power cables and rcas that were already installed in the car when I bought it, and know that they were working with the previous install. Never one to dive blindly into something, I checked all wires especially ground etc and found no problems whatsoever.
Then I wired up my sub (to test amp, didn't want to hook up my focals at test stage ). I ran the sub in car for about a week with no problems, not pushing it at all. I thought everything was ok until suddenly after about 3 mins of listening my amp cuts out, then cuts back in and out every 3 or 4 seconds (I took this to be the protection circuit kicking in?). Now, rather than happening after 3 mins or so the amp starts cutting in and out from the second the music starts.
I removed the rcas and speakers so that only the power wires are connected. The problem still occured. I multi metered the remote line and that stays steady through whole process, re-checked all earths etc and now I am at a loss.
Anyone have any ideas as to the root of my problem, or know any jbl specific problems that have occured in past?
Cheers for any help you can give
no, I just held a voltmeter on it during operation and it showed a clean 12v throughout the amp shutting on and off, so I basicly ruled out the remote lead.
Okay, well do what I suggested and post your findings. Voltage doesn't necessarily indicate current.
i didn't realise the remote switch was dependant on current, thought it just detected a p.d. of 12v
It's gotta have enough current to trip a relay.
ah, i'll try it, but i don't have any heavy gauge wire, can i get away with using thin speaker wire for a jumper?
cheers shadow, i think you've pointed me in the right direction, I didn't think about the current aspect because I figured i was only turning on one device. Forgot that my car has a factory standard electric aerial so 250ma remote current split between amp and aerial isn't much, will try jumper 2morro as i'm in the uk and it's now very dark!
also forgot to say sorry for not reading the thread about mostly the same thing (m1-atx amp turn on), did search but only found it after googling my problem.
Speaker wire's fine. It'll only pull about a half amp. You need to use a relay. The info is in that other thread.
