david.hanagan 0 Posted April 14, 2011 Report Share Posted April 14, 2011 Hi allJust wondering if there are any ICE guru's out there that can help me out. Went to football in the VR tonight, first time it has been used in a few days and for some reason my sub has stopped working. I have checked the amp and there is power going to it and it turns on with the stereo, checked the RCA leads on the amp and back of the headunit and all seem fine. Does this mean the amp is likely to be knackered? Seems strange as it has gone from working to using the car again and it not working.Can anyone suggest what might have happened or something to check? I dont have another amp to test the cables, and ideally dont want to buy new RCA's etc if they are not at fault.Any suggestions welcome.ThanksDavid Link to post Share on other sites
spadam 7 Posted April 14, 2011 Report Share Posted April 14, 2011 Have u checked the earth for the amp. This can cause all sorts of problems worth a check. Link to post Share on other sites
david.hanagan 0 Posted April 14, 2011 Author Report Share Posted April 14, 2011 Checked the earth and all seems to be ok :-s Link to post Share on other sites
spadam 7 Posted April 14, 2011 Report Share Posted April 14, 2011 What about the remote lead. As if this has come lose the headunit won't power on and off the amp when required. Link to post Share on other sites
spadam 7 Posted April 14, 2011 Report Share Posted April 14, 2011 Have you checked the remote lead from amp to headunit. Link to post Share on other sites
david.hanagan 0 Posted April 14, 2011 Author Report Share Posted April 14, 2011 That's the thing, the amp does power on so the power lead and remote must be ok but the sub doesn't work. Link to post Share on other sites
spadam 7 Posted April 15, 2011 Report Share Posted April 15, 2011 The amp can power on without the remote lead. It hard to explain what the remote lead does but without it you wont get any noise coming from the sub. Link to post Share on other sites
david.hanagan 0 Posted April 15, 2011 Author Report Share Posted April 15, 2011 Ah right i see. I was under the impression that if the remote wire wasnt connected the amp wouldnt power up at all, i thought thats what powered the amp when the stereo came on and the live was just a perm live? :-s On that note, can i use any piece of wire to act as a remote wire to test it?

Daverse 175 Posted April 15, 2011 Report Share Posted April 15, 2011 yup prety much any cable mate, its only a 12v supply with negligable current. just make sure the cable is stranded, other then that it will do. speaker wire is a good example. oh check the rem cable at the headunit first, it can come loose.. cheers Link to post Share on other sites
jimmyb 2 Posted April 15, 2011 Report Share Posted April 15, 2011 hi mate, check the wiring inside the sub its self its only two wires but if there not on it wont work! worth a try in my opinion, good luck! Link to post Share on other sites
david.hanagan 0 Posted April 15, 2011 Author Report Share Posted April 15, 2011 Hi all.I went and took another look tonight. Seems it was the remote lead after all as i cut the join behind the stereo and re-wired it and hey presto, it worked.Really appreciate your help as i figured if it powered then it couldnt have been the remote wire so i would have been hunting all night for the problem.David Link to post Share on other sites
david.hanagan 0 Posted April 17, 2011 Author Report Share Posted April 17, 2011 Hi again.Just as i solved this problem it seems to have broken again. Went out earlier and all was ok, got back into the car and the sub stopped working again, checked the amp and it doesnt appear to be powering up, well the light isnt illuminated anyway. I have checked the fuse on the amp and in line fuse and they all seem to be ok. Anything else that it could be that is stopping it powering?Kinda getting on my tits now!ThanksDavid Link to post Share on other sites

Rustyman 0 Posted April 17, 2011 Report Share Posted April 17, 2011 if you have to grind to bare metal to get a good earth ,,, & hopefully you are using the appropriate gauge size of cable to take the current Link to post Share on other sites
