slugdub Posted March 26, 2009 Report Share Posted March 26, 2009 I thought it was the new amp at first (even though is substantially bigger than any I had before) because i first tested it with the new 4 gauge wire, but now that its running lightly off 8 gauge (until tonight when I redo it) the lights are dimming again. So it appears even with the 8 gauge ground, that just running 4 gauge knu cca is stopping dimming? Is this probably the case? Quote Link to comment Share on other sites More sharing options...
E-Train Posted March 26, 2009 Report Share Posted March 26, 2009 what? are you trying to say when u had 8ga power n ground it didnt dim, n when u upgraded to a 4 ga power it started dimming?

Is this probably the case? I'm surprised that the amp isn't cutting out if it's a larger one. Larger wire with a higher strand count will allow more current to pass up until a certain point. Check your fuse rating and compare it to an ampacity table for wire to determine the minimum that you should have. I suggest just upgrading to 1/0 all around though. Quote Need an install?

Sorry if I explained it bad. I'm saying the opposite. 4 gauge no dim, but 8 has dim I'm surprised that the amp isn't cutting out if it's a larger one.

Check your fuse rating and compare it to an ampacity table for wire to determine the minimum that you should have.I suggest just upgrading to 1/0 all around though. Sorry, my 'large' is different than other people's large. Its only running at 656w rms (2 ohms) so I'm covered. 80 amp fuse. The specs say min 6 gauge wire, so I'm going already above and beyond. I'm just wondering if I'm crazy or the difference in wire stops dimming somehow. Quote Link to comment Share on other sites More sharing options...
lanman31337 Posted March 26, 2009 Report Share Posted March 26, 2009 Are you feeding the wire ham sammiches? That would make me dim too. Back to the wire, yes, your 4 gauge wire will let more current pass through than your 8 gauge. Try to put the same current through your 8 gauge and some of the amperage comes out as heat. How warm does the 8 gauge ground get?

slugdub Posted March 26, 2009 Author Report Share Posted March 26, 2009 I suppose I should give it the heat test. I haven't noticed it warm at the end going into the amp, but I haven't really grabbed it. I'll do that today @ lunch. Also, it seems the 8 gauge is letting more engine noise into the amp too, but I again, I can't tell if thats me or what. I really want to get rid of that noise.

It's also possible that your ground point sucks. Try to find a spot on the chassis to ground to if the noise is bad. EDIT:spelling Edited March 26, 2009 by Neo_frog Quote Need an install?

finkster Posted March 26, 2009 Report Share Posted March 26, 2009 I stopped using 8 gauge when i got above 400 rms...youre running more than that... And 80 amps is too much for 8 gauge IMO... x2 on finding a better ground....
