keltik Posted May 26, 2006 Share Posted May 26, 2006 Whats the remote power hooked up to? Try just powering that - eliminate any head unit problems. KELTIK Quote Link to comment Share on other sites More sharing options...
7point62fmj Posted May 26, 2006 Share Posted May 26, 2006 I would say your amp is "motor boating" (floating ground) but if you ran a lead directly from the battery for both the postive and the ground and the remote turn on and it STILL is doing it try hooking the amp up with out the speakers. IF it works (power comes on) fine you may have a bad speaker which is grounding out causeing a short. On the other hand if you hook it up directly to the battery and it does it with no spearks (no load) on it you have a bad amp. Or you may have a load that is to small for the amp..Ie speakers are wired in a "bridged mode" .. Just a thought. Quote Link to comment Share on other sites More sharing options...

SuBrat84 Posted May 26, 2006 Share Posted May 26, 2006 I had the same exact problem in my 88 RX when I was running an amp and some subs w/ a blaupunkt deck.. cutting out.. like it was over heating or something... I installed it all in the honda wagon and it works like a champ never distorts or cuts out or anything. I am 99.99% sure it is the "remote" wire. Instead of trying to wire it to whatever.. try wiring your "remote" into the wire that runs 12vdc to the stereo when the key is turned on. (not the hot wire that is always on! you don't want your amp on if your car is off) I think it's the Yellow one? or maybe Red? if you have a multimeter you can test to see which one is the hot and which one is the ign. Hope this helps. Quote Link to comment Share on other sites More sharing options...
bgd73 Posted May 26, 2006 Share Posted May 26, 2006 I hope you have the channels run for your speakers and not using subaru speaker wire setup... The shared ground is bad news. Quote Link to comment Share on other sites More sharing options...
rllywgn Posted May 26, 2006 Share Posted May 26, 2006 check the heat of the amp when its shutting off. amps are pretty straight forward when it comes to hook up. power wire with a fuse (no more then 16" from battery), ground , remote turn on (use your switched on), and your audio input RCA's. if your just running subs, the cutting out may have something to do with how the subs are wired... series, parrallel, bridged, etc.. how is yours run? also is the amp new? used? are you sure the amp isnt toast? rllywgn Quote Link to comment Share on other sites More sharing options...
()__1337_CRAYOLA__()> Posted May 26, 2006 Share Posted May 26, 2006 i've had a problem like this on an amp actually try checking you rca plugins on your amp they may require soldering if they are loose, because of the loose connection on the rca's the amp wont function. try wiggling them and if it cuts on and off thats your problem. i have to pull the one outta my soob to fix the connections pretty soon :-\ Quote Link to comment Share on other sites More sharing options...
IrocRacer Posted May 27, 2006 Author Share Posted May 27, 2006 I had it working for like 5 minutes steady sounded great and then like the light would dimm out then come back on and dimm out and over and over....Yes the remote is hooked up Quote Link to comment Share on other sites More sharing options...
keltik Posted May 27, 2006 Share Posted May 27, 2006 If it will stay powered on with no speakers attached i think we can call it dodgy wiring, otherwise it looks like a bad amp. Will it even work in other vehicles? KELTIK Quote Link to comment Share on other sites More sharing options...
IrocRacer Posted May 27, 2006 Author Share Posted May 27, 2006 haven't tried that yet b/c i don't have another car to do it Quote Link to comment Share on other sites More sharing options...
7point62fmj Posted May 27, 2006 Share Posted May 27, 2006 You dont have it mounted to the body do you. It can also ground through the chassy of the amp. You can always hook up a rely to the remote out of the head unit or the acc wire if it is a bad remote. But it sounds like a bad amp. Whish I was there I could trouble shoot it for you.

rllywgn Posted May 28, 2006 Share Posted May 28, 2006 most amps have plastic or rubber feat.. if they dont the amp doesnt ground against the case. sounds like your amp is going into protection mode.. what make and model is it? how are the speaker wires run? rllywgn Quote Link to comment Share on other sites More sharing options...
